Is it always with the same 15rd mag? Do you have another g19 mag to test with?

Also, is this while firing, or when loading the first round? If it’s the first round, describe your loading/chambering process.

 

I’ve had the same issue with multiple mags. It is always when I am chambering the first round. When I’m firing it doesn’t occur. I’ve tried both slingshotting the slide and using the slide release to make certain I’m not riding the slide.

 

I strongly suggest Speer Lawman124 or 147 grain 9mm, or some NATO 9, especially for a new Glock pistol. A better quality ammo-American Eagle, Seller Belliot [sp]

'Winny' white box quality can be hit and miss. After a few hundred rounds [of better heavier ammo] it should eat anything

Also make sure your dominant shooting wrist is locked with a very firm grip.

What happens when you use the G26 mags?

 

I’ll try some different ammo. With G26 mags there is not an issue. This simply happens when I’m chambering a fresh mag while shooting. I’ve just been using what I’ve had on hand.

 

Are you using an Xgrip or similar with the G19 mag? I understand that using the longer mag body as a grip can force it out of position and cause feed issues. I have had no experience with these types of FTF, but it’s a possibility. And a XGrip is <$20, so a small investment to see if that’s what is going on.

For what it’s worth; I have fired many, many G19 mag loads through my G26 (Gen 4) without a grip sleeve (i.e. xgrip) without issue. Yes, the mag does wiggle a little, but it’s never caused a feeding issue. I’ve also run it with an xgrip but prefer not to as I also have a G19 and use the mags with it as well.

Also fun is the 33rd mags (aka the giggle stick). Stuck in the mag well of a 26 makes it look like it could pull double duty as a hammer.

 

Edit
Question previously asked

 

My guess is that if you got yourself a few snap caps and cycled it a few hundred times that would go away. You might want to try polishing the feed ramp and chamber very gently.

 

I am wondering about this as well. While I was at the range/gun store yesterday I asked one of the RSOs about it. They pulled out 15 dummy rounds and couldn’t duplicate the issue. When I got home I tried with the Hornaday and duplicated the issue.

 

Why are you switching brands?

Only when handloading the first round, and never with firing? Happens with FMJ?

I would suggest not using Glock 19 mags for another 500 rounds fired, then revisit after the gun has run for a little, softened up.
For safety, I would suggest not playing with live rounds at home.

 

For safety, I would suggest not playing with live rounds at home.

This is an important point.

Also, since it’s not been mentioned, but just for completeness (and I’m NOT saying the OP is doing this): don’t hand cycle ammo for “testing” purposes. As we’ve seen here, the gun in question is working while firing, which is an entirely different scenario and set of circumstances versus hand chambering the first (or any) round.

I also agree with shooting it with stock mags more and letting things settle in. My G26 Gen 4 has always ran well with any ammo and mag configuration, however I’ve heard the Gen 5 may have been manufactured a little “tighter” and perhaps that’s what’s going on here.

 

It looks like the the cartridge is only half way in the chamber due to the lack of the sufficient momentum of the slide… In other words, it seems it is almost like a really bad case of FTRTB instead of FTFeed (or “nose dive”)….

Q.1 When you chamber the first round from a fully loaded 15-rounder mag, are you releasing the slide with a sufficient force (and not riding the slide)?

*The top round in a fully loaded cartridge is usually more tightly held in the magazine, and thus requires more force for the slide to strip it from the magazine and chamber it.

Q2. When you chamber the first round from a fully loaded 15-rounder mag already in the gun, how are you holding the gun (the grip) in your strong hand? Is your pinky placed on the magazine body protruding from the grip?

*Using the protruding portion of the 15-rounder magazine as your “pinky rest” can change the angle of the long magazine held in the short grip of the G26 so the loading angle of the top round can become “flatter” (i.e., more toward “nose down”) just so slightly. Combined with “riding the slide” this can also increase the risk of feeding issues with the top round.

 

This. I can cause my G27 to malfunction if I put a noticeable amount of finger pressure on a G23/22 magazine inserted in the subcompact frame. It alters the angle in how the top round feeds causing a FTF. So I just don’t use the magazine as a pinky rest.

 

So if I understand the OP -

The issue is just when you chamber the round - not while shooting the gun?

Pull harder on the slide when you rack it - it is not going to break - it has a lot more force on it when you are shooting. SLING SHOT IT HARDER!!!

Try locking the slide back - inserting a mag - pull back on the slide and let it free - do not ride the slide forward with your hand - or after locking back the slide - insert a loaded mag then drop the slide stop lever and let the slide slam forward.

I bet this solves the problem - which is you are trying to not hurt your gun and in the process not using enough force so that it can function properly.

I also think after a few more trips to the range it will become easier to load.

 

Are these 15-round magazines actual Glock-manufactured magazines, not KCl or some other brand?

Did you disassemble the 15-rounders for cleaning or something? I'm wondering if the magazine springs are in backwards.

 

Yes the 15 rounders are all Glock. I have not had them long enough to consider cleaning yet. I just started to switch over to Glock over the summer.

 

My guess is that there's too much force pushing up on the column of rounds and the RSA can't overcome the force. As you mentioned the problem goes away once the magazine gets down to 12 rounds. You could get a extra power RSA.

 

It works fine with the 10-rounders, so I think the problem less likely to be with the pistol and more likely to lie with the 15-rounders. I wouldn't want to over-spring the pistol and probably make it unreliable with the 10-rounders.

It's blowing my mind that you have to download the 15-round magazines to 12 rounds for reliable first round feed.

 

Just to review...

I’ve been having a failure to feed issue with my 26 Gen 5 when using Glock 19 magazines. It happens with Winchester White Box 115 grain and Hornaday 115 grain Critical Defense. I’ve not had an issue with the 26 10 round magazines. Once I do get the round chambered it functions flawlessly.

I’ve had the same issue with multiple mags. It is always when I am chambering the first round. When I’m firing it doesn’t occur. I’ve tried both slingshotting the slide and using the slide release to make certain I’m not riding the slide.

I’ve been giving them a good tap to make sure they are fully seated.

I’ve checked with different amounts of rounds in the magazine. It has happened as I go through trying to chamber a first round. I’ll clear the Miss feed and leave the round out and continue to attempt to chamber a round. It’s been a few times back but I think I had to go down to 12 rounds to get it to chamber.

I asked one of the RSOs about it. They pulled out 15 dummy rounds and couldn’t duplicate the issue. When I got home I tried with the Hornaday and duplicated the issue.

the 15 rounders are all Glock. I have not had them long enough to consider cleaning yet.

Is the flange of the recoil spring assembly marked with a "0", an "8", and a "2"?

I assume the 15-round magazines have been problematic from the start...?

Can you take some photos of the 15-round magazines, to include the number on the top of the follower?

Yes the issue has been occurring with the 15 round magazines since I purchased the gun new.
I will get pictures of the magazines tomorrow and post them. They are Gen 5 magazines.

 

Interesting issue.

I have a G26 gen 3 that was my off-duty gun. Qualifications with it since 2006 was twice a year, 50 rounds each qualification. Magazine used was the OEM 10-rounder in the gun, with the remaining 40 rounds loaded in 3 G19 mags. Never had an issue.

Yes, I got that your G26 is a gen 5. What I'm getting at is, use of G19/G17 mags as reloads for the G26 is likely common among the current crop of LEOs who have gen 5 pistols. But AFAIK, that's not been a similar issue reported.

What makes it more interesting is that this issue should really not be too difficult to diagnose.

So when you experience a FTF like in your photo, can you hand push (gently) the slide/bullet into battery? Or is it jammed (improper angle of bullet in chamber, etc...) that you cannot?

 

I can’t push it forward which is what is baffling me. I have no problem clearing the mis feed. I am being very careful with this. I did it one time just to check if I was having the same issue with another brand, and shape of round.

 

Don't use the slide "release" (its a slide "lock") to chamber first round.

 

If we’re going to be nomenclature nazis, what you’re referring to is the slide STOP. The slide LOCK is what keeps the slide attached to the rest of the pistol.

 

For the hell of it I tried it today w/ my 26 Gen 5 and several G19 mags. The 26 has less than 200 rounds and is about 1 year old bought new., I used new and old OEM Glock 19 mags and ammo from different manufactures including Winchester WB. I couldn't duplicate the problem. I was at a private range when doing he test.

I suspect the problem has to do with the Gen 5 breechface cut, which is a shallow channel milled into the corner of the breechface opposite of the extractor.

The failure symptom is nearly identical to using Shield Arms 15 rd magazines in Gen 5 G48s. On some pistols, the Shield Arms magazine experiences excessive front to back wiggle when seated. The wiggle interferes with the case rim feeding into the breechface cut and the action jams exactly as depicted in your photos.

There may be enough front to back wiggle with the G19 magazines to cause this problem with your particular pistol. In addition, the G19 magazine's fully loaded spring pressure may contribute to the failure, which could explain why downloading the magazine clears the problem.

 

... Failure to feed is not uncommon with some new Glocks, especially the Gen 5 with tighter tolerances…. Your problem will go away once gun broken in.…

Does Glock customer service recognize this as a problem they’d fix? It might be worth a call.

If mag wiggle is contributing to the problem as DeltaFiveBravo suspects, using a x-grip sleeve should fix it. Once your G26 has been thoroughly broken-in, the x-grip might no longer be necessary for chambering that first round.

You could use a 10 round mag to load the “Barney round” in the chamber then remove that mag and insert the 15 rounder and be good to go even without an x-grip. Just don’t use a G19 mag without an x-grip as an emergency reload until after the issue has been resolved one way or another.

 

Like they say above, it could be the "Angle of the Dangle" eh?

 

Stop using g19 mags?

 

I suspect the problem is simply the extra pressure of the top round in the G19 mags being too much for the RSA in your pistol to handle. As others have suggested, put the G19 mags away for a while and just use the G26 10 (or 12) round mags. However, don't be too surprised if using the G26 12 round mags doesnt cause the same problem! Loading my G26.4 original 3 mags with 10 rounds was fairly easy but adding the +2 base made them very difficult to load (at first... they got easier as time and the number of loadings went up) especially the last 2 rounds. Of 6 mags (3 original with added extensions and 3 OEM 12 round mags purchased a bit later) 4 would only take 11 and 2 refused to go beyond 10, while loading even the 10 was much more difficult than without the extensions). After leaving them all loaded to capacity for a couple of weeks, they will now all take 12 rounds as long as the loading tool is handy!

I will also mention that I almost immediately put an increased power (heavier) RSA in my pistol, so that may have been a factor in the perfect functioning of my G26. I do not tend to shoot very many "standard" pressure rounds in any of my guns so increasing the RSA spring weight is SOP for me. +P and +P+ are the normal loads I shoot.

And as an old time 1911 guy, I have extended slide locks on all of my Glocks and often as not use them as slide releases. Old habits die hard!

There is nothing wrong with your gun. Or how your shoot it. Or what ammo you are using. Failure to feed is not uncommon with some new Glocks, especially the Gen 5 with tighter tolerances. Put 200 or 300 rounds through it and problem will go away. If failure to feed on first round bothers you, just change mags before last round and before slide locks back. Clean barrel feed ramp from carbon build up but don’t polish it. Add some extra slide rails lube while breaking gun in. Keep slide locked back in between range trips to loosen up the RSA while breathing in. Your problem will go away once gun broken in. And you can still train while breaking in (don’t just waste ammo breaking in).

 

If you decide to go this route here is a link to an extra power RSA for a Glock 26. It's only $35. Choose the 18 lbs. option as 16 lbs. is standard weight.

OP, how many rounds have you fired since the last time the gun was cleaned and properly lubed? Have you taken the slide off and checked the rails for cleanliness and lube?

 

I field strip and clean after each trip to the range. I typically fire between 50-100 rounds per session. I try to follow the instructions in most manuals on how I clean.

 

Two things:
My G26/3 does not like Winchester white box 115 grain. It is somewhat low powered and does not energetically cycle the slide. This may be a contributing factor.
My department had issues using G23 mags in G27s. Same problem you describe. We wondered if pressure on the toe of the mag rocked the mag and caused the feed angle of the feed lips to dip a little causing the cartridge to hit the feed ramp at a little steeper angle. This, is conjunction with the lower powered ammo, may be aggravating the problem. The grip sleeve may help but no guarantee.

If you’re putting 115g in a glock 23 that is a whole different problem. Just sayin’

 

Try using two or so wraps of electrical tape on the mag near where the bottom of the mag well lines up - this will help with the "wiggle". I've never had a problem with my G26, however, others have and this worked.

Actually, placing a couple of layers of Gorilla tape strips inside the mag well on the lower back side would probably work better for the same purpose. Gorilla tape sticks very well on a well-cleaned surface of polymer frame, especially when you apply heat with a hairdryer or heat gun.

I’ve done something similar to my Kahr PM9 and worked very well, and the Gorilla tape strips have not come off for about 8 years already.

 

Where did you get the g19 mags. Are the new and are they gen4 or 5 mags with mag catch slots on both sides? Is the mag release still on the left side (right handed)?

 

All mags are Gen 5 purchased either at a local gun store or through Brownells.
