What's a 45X??
Or do you mean 43X?
Glock will never do a fifteen round mag because it will cannibalize G19 sales.

 

Yes.

No.

Maybe.

They didn’t make an extended mag for the 43, which clearly could benefit from it. So, I don’t believe Glock will ever do one for the 43x/48.

 

If Glock would have wanted a 15 round mag in the 43X they would have made one by now. I don’t see it happening.

 

From the OP, yes, I meant 43X instead of 45X my typo. Thanks for everyone’s thoughts.

 

Fixed it for you.

 

Will Glock ever make a 15 round magazine for the 45X? Shield Arms has a 15 round mag that appears to be a double stack that is exactly the same size and length as Glock’s 10 round magazine. I would much rather buy OEM instead of aftermarket.

Doubt it. The geometry just isn't there unless the grip is expanded upon and Glock won't change the design of their mag and lose the polymer overmold.

While Shield Arms has a 15 round mag it is more or less a waste of money as it isn't anywhere near as reliable as a factory Glock mag.

Is this from personal experience? Or are you parroting what you've heard on the internet. Because I have had zero (0) issues over the last three (3) years with Shield arms magazines in my G48. I do understand that there was some issues with the very first ones produced in some guns, but there are many others that have posted on various forums that, like me, have had no problems.

I can't say that I have put thousands of rounds through mine as I don't have an unlimited ammo budget, but I do shoot at least a couple of times a week at my backyard range and I always run a couple of mag loads through all of my SA mags in the course of a month. As I mentioned I have had zero (0) issues with mine. I have a bunch of other 9mm's that I shoot, so I do have to ration ammo somewhat. My suppressed MP5 and my Sig P210 seem to get most of my range ammo.

 

I don't see Glock doing it, because if they did, not only would it hurt the sales of the larger 9mm Glocks, but then they'd have to (at some point) redo every magazine for every model to get more ammo in them.

PSA has a 15rd for the G43X too, it's a better option (half metal, half polyme) in that you don't have to change out the magazine release whereas you do for the Shield Arms mags. Glock could go that route, but I just don't see them redesigning their magazines, but I could be wrong.

First hand other than a 48 that couldn't even get through a mag with the S15, people showing up at the range and choking with them, plus the numerous reports of failures and issues it really isn't a grandiose revelation they just aren't reliable. I put them on the same level as ProMag and ETS, actually lower as they wouldn't even make a good range mag option since they require a proprietary mag catch that is known to cause issues with factory mags.

I do understand that there was some issues with the very first ones produced in some guns, but there are many others that have posted on various forums that, like me, have had no problems.

And after three generations of S15 mags there are still numerous people having problems with them. One thing I have learned about the Shield Arms mags is they are one of those products that work better on the internet than in reality.

I can't say that I have put thousands of rounds through mine as I don't have an unlimited ammo budget

So how many rounds would you say you have put through them?

"And after three generations of S15 mags there are still numerous people having problems with them. One thing I have learned about the Shield Arms mags is they are one of those products that work better on the internet than in reality."

I respectfully disagree. By anecdote, even with the first generation of S15's there were only about 20% of the purchasers had various issues. As generations 2 and 3 came out fewer issues have been observed. The reason for the issues was not the magazines, but the disparity in each pistol's consistency of manufacture by Glock. One has to ask, why is every other manufacturer of poly frames having great success with metal mags? I digress.

I have S15's in all three generations and haven't had a single FTF over thousands of rounds. My good friend that has a 43x and later a 48 has had the same successful experience. In my case, when I acquired my 48 I kept the original poly mag catch primarily to use the OEM mags. But out of curiosity, I purchased two PSA micro dagger mags and they too work very well in my 48. The PSA mags, allowing me to keep the poly mag catch in my 48 significantly increased my 48's load out capacity, being able to continue to use the OEM mags from the 48 and 43x. I haven't put nearly as many rounds through the PSA mags as the S15's yet, but in both cases no FTF's (though initially there were some issues due to fraying front lips on the PSA mags which required filing smooth)..

So IMO, the statement about working better on the internet than in reality is exaggerated as there are many satisfied S15 users, which is supported that Shield Arms sells out their batches almost as quickly as they get them in stock. The initial G2 batch was sold out in minutes. And if you use this forum as the canary in the coal mine, only do S15's show up in the forum classifieds for sale every now and again. So again, there are many more successes with them than failures. However, with any piece of equipment used in self defense, even OEM, the user should be testing extensively before carrying. This goes double for 3rd party parts.

 

No. Adding 5 rounds to that design would probably result in an increase (and maybe just a statistically small one) in failures. Same reason they never tried to do so with the G36.

 

Glock does extensive and thorough testing of their mags when they are designed. This is why you frequently see people talking about aftermarket magazines not being reliable yet issues on factory Glock mags are extremely rare. You don't see all these problems with the factory Glock mags, and that's telling.


S15's get a lot of complaints. I think most people see "15 rounds" and then quickly lose sight of what's actually important. 10 rounds that consistently work reliably beats 15 rounds that are hit or miss or certain mags that work or don't work any day of the week.

The 43X is a great 10 round gun and, TBH, there isn't any real real need to shoehorn 15 in the mag.

 

I used a Shield Arms mag in my FFL's 43X that he let me shoot, and that damn thing was horribly unreliable. That seems to be the case for most experiences I've read online with that magazine. If Glock could come out with a better one of their own design, I think it would be a smash hit.

 

As I said, about 20% of the 43x's that tried S15's did not have good luck. But also understand that the 43x had somewhat of a secret update. When they switched from the silver slide to the back one I suspect there were other tweaks too.
Some time back I was shooting with a retired cop, about the time that the Gen 2 S15's came out. He had a silver 43x. Incredulously, his silver 43x shot the Gen 1 S15's flawlessly but had issues with the Gen 2 s15. If I hadn't seen it first hand I wouldn't have believed it. So, enter the S15 third generation mags. Different manufacturer, significantly updated design.

My point? There are so many variables with "failures" and perhaps successes as well that it is difficult to lump this altogether into a singular verdict. On the other side of the equation, over thousands of rounds I've had some failures with my OEM mags than I've had with the S15's or the PSA mags. The thing is that Glock, designing for Glock parts has a very wide window of QC acceptability. Some mag wells are too elongated and cause seating issues. Some mag wells form too wide and can cause inadvertant mag ejection of S15, even with the standard steel mag catch (though a longer catch is availalble to solve that issue. So between the longer mag catch and the rib on the back of the G3 S15 I suspect the failure rate initially seen with S15's has narrowed considerably. Not to make excuses for Shield Arms, but when the S15's came out initially, there weren't a lot of 43x's available for modeling. And as stated the wide spec of the Glock frames had Shield Arms almost spitballing the design. Unlike S/W and Springfield whose steel mags were designed in conjunction with poly frame designs I think SA did a pretty good job of getting close the first time and closer with each generation. Those who are afraid of the expense and possible failure or cannot commit to extensive testing should, of course, stay with OEM mags.

 

The appeal of the G43X to me is not only its thinness but also its lighter weight thanks to the ten round magazine. If I wanted fifteen rounds I would just carry one of my G19.5. I’m glad we have more choices in pistols than ever before. I love my Glocks and I really love my G43X. My opinion only!!! 🇺🇸🇺🇸🇺🇸

 

I think 10+1 rounds is the sweet spot for normal edc and that makes the 43X a great carry gun along with its other attributes.

 

“I think 10+1 rounds is the sweet spot for normal edc and that makes the 43X a great carry gun along with its other attributes.”

We agree. We grant this is subjective, but for our $$$, the G43X is the best combo of size/weight/capacity/shoot ability we have seen so far. Don’t feel any urgency to up the capacity for the G43X intended mission.

Having said this, we recently purchased two PSA 15-round mags; and in limited testing they are (so far) 100% reliable with the ordnance we have loaded in them.

We trudge on.

 

I've been trying to get a couple of the PSA 15 round magazines and when I see the email that they are back in stock and I try to order them, they are already out of stock! You all are way too fast ordering them!

 

I've had good luck with S15 mags. Both gen 2 and 3. Glock will never make one. You have 3 choices. SA, PSA and OEM.

Personally, I think most folks will make it home with 11 rounds in the gun and a spare 10 rounder.

 

Will they ever make them as originally asked? I think it's a very definite possible maybe that is highly unlikely.

 

Like others, I say unlikely as it would hinder full-size sales. Glock is in business to turn a profit and that move goes against the grain.

 

Anyone really serious about SD carries an extra round regardless of capacity. Not for more bullets...more reliability

 

My experience has been the opposite. Did you try them in your own 43X?

Well, let's think about this for a minute. If I have already had them go down in a 48, why would I need to continue to use them and put them in another gun?

Some, like me, have had excellent results while others have had horrendous experiences.

Sounds about par the course for aftermarket Glock magazines.

That's your own, rather flawed determination. They don't work in a 48 so therefore they won't work in a 43X? They work every bit reliable as the OEM mags in mine. Single sample but to me, my sample is the one that counts the most From your statements the answer to have you tried your own magazines in your own 43X is a no. Not sure but do you even own a 43X?

I have 3 gen 1 S15 mags and 3 Gen 2 S15 mags 2 of them w/plus 5 extensions. I would say at or about 1,000 rds. thru all 6 mags no issues or concerns or failures to report, but still in the back of my mind will it fail when needed. All so have the 2gen mag catch release. So I install from Glock store the plus 2 on my OME mags and that is what I carry.

Speaking of flawed determinations, they failed in a 48 that I personally used plus numerous people complain of them failing in the 43X. There's one or two in this thread that have reported failures. That pretty much establishes the benchmark they are NOT as reliable as the factory mags.

Having already established the fact they failed once, I don't need to continue using them any further. And certainly don't need to keep running them and damage the mag release in a completely different gun.

But do tell me more about my flawed determinations and bad reasonings. 👌

Not sure but do you even own a 43X?

I thought we already did this dance in the other thread?

Somehow, I'm not at all surprised.
