    ProMag Industries Glock 44 18-Round Magazine

    If you're looking for an off-the-shelf Glock 44 15+round magazine, you may want to consider the ProMag Industries Glock 44 18-round magazine,

    [​IMG]

    ProMag Industries has a horrendous reputation when it comes to magazines, however, the ProMag Industries Glock 44 18-round magazine has performed surprisingly well in preliminary tests with 15 rounds. And they only cost $13.

    Experimentation

    Warning: Don't attempt to pry apart the ProMag Industries Glock 44 18-round magazine load assist tabs!

    Unlike the OEM Glock 44 magazine load assist tabs (which can easily be pried apart with a standard screwdriver), the ProMag magazine follower and load assist tabs are a single, integrated part. And it's a B|TCH to get out! In a nutshell, you need to pinch both load assists at the same time in order to get the integrated follower / load assist tabs past the slots and out of the magazine. It's much easier to reinsert the integrated follower / load assist tabs into the magazine.

    Texas-Mark is experimenting with the use of an OEM Glock 44 magazine spring, cutting down the ProMag spring and a Taylor Tactical Supply Walther replacement spring in order to increase capacity, improve reliability and ease loading.

    Those interested in an even higher-capacity magazine may want to experiment with the ProMag magazine in conjunction with a +5 or +6 magazine extension (e.g., 2A3D, Mr. 380 EZ Products, foxalex, ...). The rather stout ProMag magazine spring may be well suited for this application.

    Magazine Extensions

    One way to increase the capacity of an OEM Glock 44 magazine is by using a magazine extension.

    With larger magazine extensions (e.g., +5, +6, ...), in order to take advantage of the increased capacity, you must remove the load assist tabs. You can separate the load assist tabs by getting up under one tab using a standard screwdriver and gently prying them apart. The load assist tabs won't be permanently damaged in the process.

    In significantly increasing the capacity of a magazine, you will typically need a longer spring. Refer to Replacement Springs.

    [​IMG]

    OEM Glock +2 Magazine Extension

    An OEM Glock +2 magazine extension (SP07151) and, optionally, an OEM Glock magazine extension insert (SP07165), can be used to increase the magazine capacity of an OEM Glock 44 magazine by three rounds (+3),

    [​IMG]
    (OEM Glock +2 Magazine Extension and Insert)

    Alternatively, you can use a $3 Chinese knock-off (AliExpress / Magorui) +2 magazine extension and insert. You can also purchase the insert on eBay for $2 (seller lxranes9).

    The OEM Glock +2 magazine extension is intended to be used with a Glock 9 mm, 40 S&W or 357 double-stack magazine. In order to be used with the smaller OEM Glock 44 magazine spring, the magazine extension must be "padded" (made more narrow) to keep the spring from twisting / contorting.

    Refer to the "Alex Alex" Glock 44 15-Round Magazine Conversion for more information.

    2A3D

    2A3D offers a 3D-printed +6 magazine extension for $25 (including shipping). The magazine extension is currently only sold through the Facebook, Instagram or E-mail.

    Observation: The 2A3D magazine extension doesn't have "slots" to accept the "tabs" on either side of the Glock 44 magazine. A set screw (that I've already managed to lose) is intended to secure the magazine extension. The set screw would normally protrude on the outside of the Glock 44 magazine,

    [​IMG](2A3D +6 Magazine Extension with Missing Set Screw)

    Mr. 380 EZ Products

    Mr. 380 EZ Products offers +1 and +5 magazine extensions. The +1 magazine extension is meant to be paired with the Mr. 380 EZ Products +4 cut-down follower.

    [​IMG]

    (Mr. 380 EZ Products +5 Magazine Extension)

    Observation: The Mr. 380 EZ Products magazine extensions have "slots" to accept the "tabs" on either side of the Glock 44 magazine.

    Alex Alex (foxalex)

    "Alex Alex" (foxalex) has posted a 3D-printed +5 magazine extension on Thingiverse (free) if you have access to a 3D printer,

    (foxalex +5 Magazine Extension)

    Observation: The foxalex magazine extension doesn't have "slots" to accept the "tabs" on either side of the Glock 44 magazine. The foxalex magazine extension is simply secured by friction.

    Experimentation

    You may want to experiment with pairing a +5 or +6 magazine extension (e.g., 2A3D, Mr. 380 EZ Products, foxalex, ...) with a ProMag Industries Glock 44 18-round magazine. The rather stout ProMag magazine spring may be well suited for this application.

    Magazine Loaders

    We all know a magazine loader can simplify the task of loading a magazine. This can be especially true with Glock 44 magazines.

    The OEM Glock 44 magazine has rather effective load assist tabs, however, the load assist tabs are oftened removed to increase the capacity (e.g., cut-down follower and/or magazine extension). A magazine loader can be very beneficial in this situation.

    The ProMag Industries Glock 44 18-round magazine has load assist tabs, however, they're small. This combined with the ProMag magazine's double-stack design and stout spring make a magazine loader even more beneficial.

    There are two basic styles of magazine loader ...

    One style wraps around the magazine (i.e., wrap-around style) and leverages the load assist tabs. This is very effective with the ProMag magazine. However, obviously, this style of magazine loader doesn't work with a magazine without load assist tabs.

    The "hood style" magazine loader slips over the magazine and a post in the top of the hood depresses the top-most round. Some GlockTalk community members have expressed concern with this style of magazine loader denting .22 LR rounds, especially with the ProMag magazine. The OEM Glock 44 magazine spring and Walther springs are less stout. This may ease concerns. The hood style magazine loaders have proven effective with the OEM Glock 44 magazine.

    The maglula UpLULA is a popular magazine loader, however, the UpLULA doesn't support the OEM Glock 44 magazine nor ProMag Industries Glock 44 18-round magazine at this time (September 2020).

    spectrumadvmfg (eBay) offers a 3D-printed Glock 44 magazine loader,

    Initial Evaluation

    OEM Glock 44 Magazine

    Note: The spectrumadvmfg magazine loader was designed to be used with the OEM Glock 44 magazine ... assumingly with its load assist tabs. This evaluation was conducted with the load assist tabs removed. Of course, a magazine loader is most beneficial in the absence of load assist tabs.

    The spectrumadvmfg is a "hood style" magazine loader (i.e., a hood slips over the magazine and a post in the top of the hood depresses the top-most round).

    There's a considerable amount of "slop" from side to side. This may be due to the absence of the load assist tabs. The post seems to catch on one side of the magazine "mouth" more so than the other. Of course, if the post is positioned directly over the last round, the magazine loader works fine. There is a little slop from front to back, however, the post doesn't seem to catch on the mouth of the magazine.

    ETA: This evaluation was conducted with an "Alex Alex" cut-down follower. In loading the first round, the post in the top of the hood presses down on the rear of the follower. This cants the front of the cut-down follower up and it catches on the front of the magazine. This issue is likely specific to the cut-down follower and is remedied my manually loading the first round.

    The spectrumadvmfg magazine loader was able to successfully load all 15 rounds in an "Alex Alex" Glock 44 magazine. In short, the magazine loader works as designed.

    ProMag Industries Glock 44 18-Round Magazine

    Note: The spectrumadvmfg magazine loader was not specifically designed to be used with the ProMag Industries Glock 44 18-round magazine.

    The spectrumadvmfg magazine loader with the ProMag Industries Glock 44 18-round magazine exhibits similar slop and challenges from side-to-side. However, unlike the OEM Glock 44 magazine, the slop from front to back seems more apt to catch on the (back of the) mouth of the magazine.

    The spectrumadvmfg magazine loader starts to struggle around round eight. The ProMag magazine spring is stout. The spectrumadvmfg magazine loader simply doesn't seem up to the task. This is likely not specific to the spectrumadvmfg magazine loader, but rather hood style magazine loaders in general.

    A magazine loader that takes advantage of the ProMag magazine load assist tabs may be a better choice. Alternatively, GlockTalk community members are evaluating the OEM Glock 44 magazine spring and Walther 15+1 spring in the ProMag magazine. This shorter and light-gauge spring may make the spectrumadvmfg magazine loader viable with the ProMag magazine, respectively.

    Mr. 380 EZ Products

    ProMag Industries Glock 44 18-Round Magazine Loader

    This is a wrap-around style magazine loader. More so than most other magazines (G44 or otherwise), the way in which the ProMag magazine is loaded is crucial. There's a fair amount of friction between the magazine loader and the magazine. The follower / load assist tabs don't relax between rounds as well as in the absence of a magazine loader. The key is to load rounds as if you didn't have a magazine loader (or load assist tabs) and use the magazine loader to assist in depressing the load assist tabs, rather than solely using the magazine loader to depress the load assist tabs to the point you can easily slip in the next round. At that point, you've likely depressed the load assist tabs too far. The magazine loader must allow the follower / load assist tabs to relax between rounds in order to maintain pressure on the previous round(s).

    ViperR (DIY)

    And make sure to check out the ViperR Glock 44 Magazine Loader (DIY modified OEM Glock 9 mm / .40 S&W magazine loader).

    [​IMG]

    Note: The author has found the ViperR Glock 44 magazine loader to be very effective with an OEM Glock 44 magazine (with and without the load assist tabs).

    Cut-Down Followers

    One way to increase the capacity of an OEM Glock 44 magazine is by using a cut-down follower. A cut-down follower will increase the capacity of an OEM magazine by up to five rounds (+5). In order to take advantage of the increased capacity, you must remove the load assist tabs.

    Alex Alex

    One option is to cut down the OEM follower,

    [​IMG]
    (DIY Cut-Down OEM Glock 44 Magazine Follower)

    Refer to the "Alex Alex" Glock 44 15-Round Magazine Conversion for more information.

    Mr. 380 EZ Products

    Mr. 380 EZ Products offers +4 and +5 3D-printed followers.

    [​IMG]
    (Left: OEM Follower; Center: Mr. 380 EZ Products +4 Follower; Right: Mr. 380 EZ Products +5 Follower)

    Initial Evaluation (September 2020)

    It's important to understand the Mr. 380 EZ Products business model. Mr. 380 EZ routinely develops 3D-printed parts and sends them out for evaluation, rather than conducting extensive "in-house" testing. Clearly, the +4 and +5 followers I received were prototypes.

    The 3D-print quality on the base of the Mr. 380 EZ +5 follower was much better than the +4 follower. Consequently, the +5 follower more securely attaches to the spring. The 3D-print quality of the +5 follower is very poor in general. Two of the four +4 followers (which weren't used) wouldn’t even slide smoothly into the magazine.

    The +4 follower is almost IDENTICAL (dimension-wise and with the exception of the poor 3D-print quality) to the "Alex Alex" OEM cut-down follower.

    Mr. 380 EZ Products +4 3D-printed Follower

    The Mr. 380 EZ Products +4 follower was tested with an “Alex Alex” magazine. The Mr. 380 EZ Products +4 follower was substituted for the "Alex Alex" cut-down OEM follower. One magazine failed to feed on round #3. The other magazine didn't exhibit any failures. Both magazines were reloaded with the exact same results. Given the 3D-print quality and fit of the Mr. 380 EZ +4 follower, the results didn't come as a surprise. The fact the failure occurred on round #3 twice was somewhat surprising.

    Mr. 380 EZ Products +5 3D-printed Follower

    The Mr. 380 EZ Products +5 follower was tested with an OEM Glock 44 magazine (with the OEM load assist tabs and insert removed). Both magazines failed to load the last round. By failed to load, I mean the round never left the magazine (i.e., never hit the feed ramp). The round was still in the magazine when I removed it. Initially, I thought the OEM spring wasn't up to the task with the +5 follower. This wouldn't have come as a surprise as the "Alex Alex" 15-round conversion requires a longer spring. However, the Mr. 380 EZ +5 follower was "advertised" to work with the OEM spring, so that's how I ran it. However, when I returned from the range, I swapped out the OEM spring for a Walther 15+1 spring and experienced similar results in manually cycling the slide. There's something about the +5 follower the Glock 44 doesn't like. Unfortunately, I'm not smart enough to figure out what it is.

    Summary

    I had high hopes for the Mr. 380 EZ Products 3D-printed followers. The +4 follower would've been a nice alternative to the "Alex Alex" OEM follower for those not interested in DIY. However, at a minimum, the 3D-print quality needs to be improved. And I'm not sure even with improved 3D-print quality, the dimensions of the follower are quite right. My goal has always been an OEM Glock 44 15-round magazine (without a magazine extension). The +5 follower could've met this goal. The print quality is good, but as you can imagine, a +5 follower is REALLY cut down. There's not much left. And, apparently, there's something missing. I'm not sure how much more time I'll spend on the 3D-printed followers going forward.

    Replacement Springs
    In significantly increasing the capacity of a magazine (either by cutting down the follower and/or adding a magazine extension), you will typically need a longer spring. There are two options. One option is to stretch the OEM Glock 44 magazine spring. However, there is a concern that the spring will return to its original length after repeated use. The other option involves using a replacement spring.

    Taylor Tactical Supply / Walther Magazine Springs

    Several community members are trialing the Walther PPQ 22 15+1 Replacement Magazine Spring from Taylor Tactical Supply,

    [​IMG]
    (Walther PPQ 22 15+1 Magazine Spring)

    The width and depth of the Walther 15+1 spring are approximately the same as the OEM spring, however, the OEM spring is a heavier gauge (1 mm vs 0.8 mm). The OEM spring has 16 coils. The Walther 15+1 spring has 19 coils.

    A few observations from G8V8 ...

    [​IMG]
    (Walther P22, P22Q, P22QD, PPK, PPKS, SP22 13+1 Magazine Spring)

    The smaller gauge wire of the Walther springs takes up less space compressed per coil as compared to the OEM Glock 44 10-round spring. The OEM spring and Walther 13+1 round spring are the same length with 16 and 14-1/2 coils, respectively.

    An OEM Glock 44 magazine combined with the Walther 13+1 round spring, OEM follower (not cut down) and padded OEM Glock +2 magazine extension holds 13 rounds.

    An OEM Glock 44 magazine combined with the Walther 13+1 round spring, cut-down follower and OEM Glock 44 baseplate / insert holds 14 rounds.

    OEM Glock 44 Magazine Spring

    If in increasing the capacity of your OEM Glock 44 magazine you replaced the OEM spring, don't throw it away! It may be possible to use the spring as a replacement spring in another magazine. For example, Texas-Mark is experimenting with the use of an OEM Glock 44 magazine spring in a ProMag Industries 18-round magazine in order to increase capacity, improve reliability and ease loading.

    Raiseek Magazine Disassembly Tool

    Anyone who’s tried to remove the baseplate from a Glock magazine knows it’s an absolute bear. Every Glock owner needs a magazine disassembly tool. This tool will also work with the ProMag Industries Glock 44 18-round magazine.

    A number of companies manufacture similar Glock magazine disassembly tools. This is a Raiseek magazine disassembly tool … $13.99 Amazon Prime including front sight installation hex tool and pin punch or $8.99 Amazon Prime stand-alone.

    $29.93 (+ $7.85 shipping)​

    The foam insert is expensive (2.5 times more expensive than the MTM AC-11 ammo can itself), however, the magazines fit perfectly and the layout of the foam insert optimizes the number of magazines.

    You're welcome. This is primarily just a "framework" at the moment. A lot more information will be added over the coming weeks (not only by me, but by the broader GlockTalk community).

    We started the "Alex Alex" Glock 44 15-Round Magazine Conversion thread over a month ago. However, that thread morphed into something much bigger and better with the introduction of 3D-printed parts (magazine extensions and followers), replacement springs, magazine loaders, ... and the ProMag Industries Glock 44 18-round magazine. There are now three GlockTalk threads dealing with the ProMag magazine. There will certainly be more ProMag magazine threads over the coming months.

    This is my attempt to reorganize all of the information under a single umbrella given the constraints of the GlockTalk forum (e.g., 10,000 characters per post). Don't get me wrong ... GlockTalk is one of the best industry forums in which to maintain this information. Facebook forums are worthless.

    I have a pet peeve in that I hate to have to read an entire thread with hundreds (or thousands) of posts in order to garner all of the relevant information. My goal is to work with the GlockTalk community in order to roll their contributions up into a "pinned" post that is directly accessible from the Table of Contents.

    Please check back from time to time.

    I've updated the Magazine Loaders post with an initial evaluation of the spectrumadvmfg (eBay) 3D-printed Glock 44 magazine loader with both the "Alex Alex" Glock 44 15-round magazine (pass) and the ProMag Industries Glock 44 18-round magazine (fail).

    At a same range session I ran more 22LR ammo thru the G44 and the G44/G19.5 hybrid. I ran SK Standard Plus thru 3 Promag 18 round G44 mags loaded to 18 rounds without any issues at all. This is the 3rd range session where the Promags have performed very well.

    I also shot 16+ mags worth of SK Standard Plus and Remington Standard Velocity 22LR thru 4 Glock 44 mags with WBN-style +2 extensions. 2 of the 4 used G44 mag springs (coded "G" in later discussions) and 2 used Walther PPQ 15+1 mag springs (coded "W"). Each mag held 15 rounds.
    Unless noted, each mag in the following report was loaded to 15 round capacity.

    a. Mag 1AW: 7 mags, 1 Failure to lock slide on last round on initial mag. No failures after first mag.
    b. Mag 2AG: 2 mags, 2 FTF caused by insufficient spring pressure caused by spring jamming with coils interleaved.
    c. Mag 3AG: 2 mags, Zero failures.
    d. Mag 7AW: 2 mags, Zero failures.

    Wanting to determine the cause of the FTF on mag 2AG, I swapped the +2 Extension bases and inserts with Mag 3AG.

    Mag 3AG experienced 3 FTF in each of 3 mag loads. Mag 2AG, now with base 3A, had zero failures over 4 mags.

    I did other base swaps and always the FTF followed the 2AG base extension. All the FTF were characterized by no or very light upward follow pressure to the point that inverting and shaking the mag would let the rounds fall out while the follower remained stationary.

    Comparing the 4 base inserts, I discovered that the base of the slot in 2AG was .03""-.05" wider than the base of the slots in the others. I padded the bottom .10" of the slot to a width of about .25", just slightly wider than the Glock spring coil width, and reassembled. This held the bottom coil very stationary and centered in the slot. This mag now has very smooth operation with no detected conflicts.

    Range time will tell if this is the solution but I am optimistic.

    Cool! I think I'm just gonna install some Pearce's and use the stock springs. Worked well on my G17 magazines.
    I'll try a Promag too. Eighteen rounds is what's up!

    Just be aware of the width of the OEM spring as compared to the width of the Pearce magazine extension. The OEM spring (and the lighter-gauge Walther springs) have a tendency to contort if given too much room. You may want to skim through the "Alex Alex" conversion thread if you haven't already.

    Glock 44 15-Round Magazine Conversion with +5 Follower

    OEM Glock 44 Magazine with:

    Load Assist Tabs Removed
    OEM Spring
    OEM Base Plate Insert Removed
    OEM Base Plate
    Mr. 380 EZ Products +5 Follower

    Range Report and more in-depth review to follow. All I can say at this point is 15 rounds fit into an OEM Glock 44 magazine with the OEM spring and base plate (i.e., no magazine extension). That's an accomplishment in and of itself. If it works with the OEM spring that further reduces the cost of the conversion.

    Warning: Don't attempt to pry apart the ProMag Industries Glock 44 18-round magazine load assist tabs!

    Unlike the OEM Glock 44 magazine load assist tabs (which can easily be pried apart with a standard screwdriver), the ProMag magazine follower and load assist tabs are a single, integrated part. And it's a B|TCH to get out! In a nutshell, you need to pinch both load assists at the same time in order to get the integrated follower / load assist tabs past the slots and out of the magazine. It's much easier to reinsert the integrated follower / load assist tabs into the magazine.

    More to come regarding my motivation for removing the follower.

    I'm trying to get a little more organized. As you can imagine, I have magazines and magazine parts laying all over the place. As you can see, I put together a nice chart to track today's results, however, I wasn't smart enough to label the individual magazines before I got to the range. I really need to track magazines from range trip to trip.

    All of the magazines were loaded with CCI Mini-mag high-velocity 40 grain copper-plated round nose ammunition (MPN 0030) the night before. In addition, magazines B1, B2, C1, C2 and D8 were re-loaded one or more times (as listed) at the range in order to re-verify certain results.

    I have over 700 rounds through my Glock 44 and I haven't performed any maintenance.

    The 3D-print quality on the base of the Mr. 380 EZ +5 follower is much better than the +4 follower. Consequently, the +5 follower is more securely attached to the OEM springs than the +4 follower is attached to the Walther 15+1 springs. The 3D-print quality of the +5 follower is very poor in general. Two of the four +4 followers (which weren't used) wouldn’t even slide smoothly into the magazine. The +4 follower is almost IDENTICAL (dimension-wise and with the exception of the poor 3D-print quality) to the “Alex Alex” OEM cut-down follower.

    ML1. spectrumadvmfg (eBay) 3D-Printed Glock 44 Magazine Loader. This magazine loader was used to load all of the OEM Glock 44 magazines. There's a detailed review under Magazine Loaders. Note the caveat in the review as it relates to cut-down followers.

    ML2. Mr. 380 EZ Products ProMag Magazine Loader (Prototype). This magazine loader was used to load all of the ProMag magazines. I have yet to update the review under "Magazine Loaders", however, it worked extremely well.

    A. This is an OEM Glock 44 magazine with the Mr. 380 EZ Products +5 follower (and the OEM load assist tabs and insert removed). Both magazines failed to load the last round. By failed to load, I mean the round never left the magazine (i.e., never hit the feed ramp). The round was still in the magazine when I removed it. Initially, I thought the OEM spring wasn't up to the task with the +5 follower. This wouldn't have come as a surprise as the "Alex Alex" 15-round conversion requires a longer spring. However, the Mr. 380 EZ +5 follower was "advertised" to work with the OEM spring, so that's how I ran it. However, when I returned from the range, I swapped out the OEM spring for a Walther 15+1 spring and experienced similar results in manually cycling the slide. There's something about the +5 follower the Glock 44 doesn't like. Unfortunately, I'm not smart enough to figure out what it is.

    B. This is an "Alex Alex" magazine with the Mr. 380 EZ Products +4 follower substituted for the "Alex Alex" OEM follower. One magazine failed to feed on round #3. The other magazine didn't exhibit any failures. Both magazines were reloaded with the exact same results. Given the 3D-print quality and fit of the Mr. 380 EZ +4 follower, the results didn't come as a surprise. The fact the failure occurred on round #3 twice was somewhat surprising.

    C. The "Alex Alex" magazines with the Walther 15+1 springs and my padded OEM +2 magazine insert didn't exhibit any failures. I've yet to have a failure with these magazines.

    D. These were the first failures I've encountered with the ProMag magazines. I have been introducing additional magazines and I tore apart (and reassembled) one of these magazines (not smart enough to label which one). The failure to feed with magazine D8 didn't come as a surprise as the first round literally fell out of the magazine as I went to insert it into the frame. I attempted to unload and reload the top few rounds, however, clearly ... this didn't resolve the issue. Subsequently, I re-loaded this magazine twice without a failure. Overall, I continue to be impressed with the ProMag magazines.

    I had high hopes for the Mr. 380 EZ Products 3D-printed followers. The +4 follower would've been a nice alternative to the "Alex Alex" OEM follower for those not interested in DIY. However, at a minimum, the 3D-print quality needs to be improved. And I'm not sure even with improved 3D-print quality, the dimensions of the follower are quite right. My goal has always been an OEM Glock 44 15-round magazine. The +5 follower could've met this goal. The print quality is good, but as you can imagine, a +5 follower is REALLY cut down. There's not much left. And, apparently, there's something missing. I'm not sure how much more time I'll spend on the 3D-printed followers going forward.

    I love my six "Alex Alex" magazines with the exception of the OEM +2 magazine extension (I just don't care for magazine extensions in general). I'm waiting on four more ProMag magazines. That'll bring my total to 12. I think I'll settle on these 18 15-round magazines for now while we wait for OEM Glock 44 15-round magazines or a "better" (?) aftermarket 15-round magazine.

    Good write-up. Well organized.
    I too have come to like the Promags and have had no problems with them over the last 3 range trips. The springs have softened with repeated use and problems have dropped off to zero. Part of it may be that I have gotten better at loading those mags and glancing thru the slots to make sure the rounds have stacked in their "normal" pattern. Depressing the assist tabs too far or not relaxing them between rounds can permit round to stack incorrectly. I have a Mr380 Promag loader inbound and hope that will make loading these mags a little easier and a bit more consistent.

    My extended base A-A/WBN mags are doing very well also with both the OE G44 springs and with the Walther 15+1 springs. The last problem I had was with one of the padded-up WBN extension inserts. I got the slot too wide and it permitted the spring to twist and bind. It is hard to get consistency when potting and sanding and grinding by hand. 3 out of 4 worked great. the 4th suffered for over-grinding but has been repaired and functions great. I feel the WBN insert concept works better than the A-A 3-D printed insert. The only significant difference between my insert and the WBN insert is that I padded mine up at the shallow end to bring the epoxy up flush with the extension's mounting groove so that there was no gap between it and the bottom of the mag body.

    Again, WBN, great job. Every cause needs a champion and you were the one this cause needed. Thank you.

    I noticed that the cut down OE followers are a little more prone to rocking, side-to-side. than the virgin ones. The unmodified followers extend deeper into the mag body and are better supported from rocking. When I saw photos of the very short, 3-D printed followers I had my doubts.
