Glock 10 round mags not as reliable. WTF

[matto]

I'm late to the party in learning that Glock 10-round 19/17/34 magazines are not as reliable as full capacity magazines.

WTF is the point of a Glock if you don't get it's full reliability? How can Glock let this continue to happen for multiple generations? Why are more people not giving them sh!t over this?

What I'm not understanding is - why the fcuk didn't they just put a spacer in the bottom of a normal magazine. It seems both a) simple and b) retains 100% of the functionality and reliability of the original magazine? Why on earth would they go and create whole new single stack design that is less reliable? And why did they continue with this broken design over many years and multiple generations? Seriously, I'm baffled here.

As you noted old news. Somewhere I have two G19 10 rounders. Have them marked as T1 & T2 (Training), use only for training on the range. Normally load less than 10 rounds, no malfunctions. So far only lived in free states (well CA, but my G17 and standard capacity mags were legal then).

If stuck in Mag limit state, no joy. Lobby PMag to make a quality 10 round or try switching out OEM followers if you can find any.

YMMV, good luck.

I was thinking a glock 26 with a +0 extension. But that's another way to go.


Just not getting why they passed on the obviously effective solution. I guess the best I can do is vote with my wallet and take my money elsewhere.

I suspect Glock believes they designed a new and reliable ten round magazine, but it fits the 43X and 48. The surest way for them to develop a reliable one for the 19/17/34 is for a Dem trifecta in November.

Even if there is a Dem trifecta, how are you going to get that many people who never shoot their guns enough to actually figure out their shite 10-rounders for their Glock Perfection aren’t worth the plastic and sheet metal they’re made from? Besides, like you said, Glock already gave everyone a solution. The G43x/G48. Why admit that you fucked up on making low cap mags for generations when you can just sell everyone new shiny things?

Yeppers.

I believe it's a simple business decision. Where is the market for a reliable 10 round Glock 19/17 magazine - at best, in magazine ban areas, no? The people buying new Glocks there, are they buying a Glock 19/17 "for protection", as a first pistol? I would say not.

As far as Glock goes, they are busy selling every G43X/G48 they can make - My guess is they would not invest resources into an R&D program to develop a different 10-round mag, when they don't see the profit. They put in a huge effort to transition to the 10 round 43X/48 mag, accepting mag incompatibility with legacy double stack products like the G19/17, as well as the G43 single stack, even. I think they saw the success of the P365 and wanted a piece of that - I don't blame Glock one bit.

Given that Gen4 pistols aren’t even on the list in California, what magazines are people feeding their Gen3 9mm Glocks that are buying new?

[matto]

I don't blame Glock one bit.

You don't blame glock for introducing a non-functional 10-round many years ago? Rather than simply pinning / blocking the existing mags, they spend the time and money to design a new magazine that doesn't work properly? And kept it on the market for what, 20+ years?

When all the other manufactures got it right?

You don't blame Glock for that?

The 43x/48 aren't relevant to that discussion.

Non functional is an exaggeration. For most people, a Glock 17/19 ten round magazine is not the weakest part of their system. People that were concerned, carried a 26 or 19 chopped to hold 26 mags. With the introduction of the 43X and 48, most of those folks have gone to the slim line pistols as they carry so well.

[Yute]

In my experience, Glock factory 10 rounders are reliable with FMJ ammo. The issue seems to be with HP ammo.

For my self defense pistols loaded with Hornady Critical Duty I use standard magazines blocked/riveted to 10 rounds without any issue. They are not range mags so cleaning is not an issue.

[exuberant]

There's several ways around this, if you cannot legally acquire standard capacity magazines in your state.

Easiest ways are to either buy blocked standard capacity mags from somewhere like Jestice Arms, or buy the Magpul 10 round mags.

Another way is to buy the 9mm6 or 9mm7 followers that are found in the normal Glock 19/17 standard capacity mags, and fit the follower to the magazine.

These aren't my pictures, but if you look at the top of the circled area on your 10 round magazine, there's a small tab that will prevent a 9mm6/9mm7 follower from rising all the way to the top. You can file this down until the follower clears it, or file the corresponding area on the follower until it does the same thing.

https://i.imgur.com/r2aBT0s.jpg

With the stock OEM 10 round Glock mags, people usually find that they feed FMJ training ammo fine, but that JHP ammo binds on the feed ramp. If you do this, the magazine should now feed just like a standard capacity magazine. I did this with 4 magazines, and shot a little over half a case of 9mm 147gr Federal HST through a Glock Gen 3 19 with no issues. The witness holes on the back of the magazines don't correspond with the position of the rounds anymore after this modification though, if that's important to you.

The 43X and 48 are indeed relavant, because they are a 10 round option Glock offers. The Glock 26 is another. You don't have to buy one. It's unfortunate that Glock corporate hasn't solved your particular problem, for your particular state, for your particular desire.

If you don't like magazine bans, you should blame the people who voted in the politicians who drafted and passed this legislation. If you don't like what Glock offers, I'm sure there are other legal options commercially available.

Good luck with your choice.

Doc I wasn't aware the OP had stated they were in Cali. I just assumed it was a generic mag ban state question. You are correct, G43x/G48 do not appear on the Cali handgun list.

That’s interesting and I’ve not seen or heard of that one before. I’ve got about 4 Glock OEM 10-rounders at home of various vintage. I might have to break them out as well as some sandpaper and see if I can make some things work.

That's an interesting observation. I must admit that while as I mentioned I've never had any operational issues with my G17/G19/G21 Glock 10 round OEM magazines, I've only used 'em to the best of my recollection with ball ammunition; I'll have to see how they do with duty hollowpoint cartridges-thanks for the insight.

Did you find out for yourself that the 10-RD mags having issues with SD ammo?

I'm from a restricted state so 10-RD is my only option, G-19 Gen-4, (6 mags) I've shot thousands of regular range ammo 115,124,147, also good few hundreds of SD ammo from different brands, Gold Dots, Hornady FTX & XTP. Remington Golden Saber Black Belt & later models.

I really don't recall any problems with the SD Ammo.

If it came to that, I have a better idea.. My HK45C LEM.. 8rd mags work just fine, as do the 10rnd elephant foot mags, and 10rnd HK45 mags also work. Accurate, reliable, and makes a little bigger hole, not much bigger than a G19. What’s not to like?

[Larry Sellers]

I’ve been down this road living in a capacity limited state. Tried all the follower/spring combinations that are recommended. Fmj is a non issue with the 10 round mags, you start getting issues with the JHP etc and there is no remedy. Armorers class does not recommended the 10s for duty carry. Guess who takes those classes?
Cops etc, who aren’t bound by the magazine capacity limits.

I tried the Magpul magazines and didn’t get the warm and fuzzys from the stoppages that I had. I carried a g43 with a reload until the g48 arrived and that’s what I have been carrying since it was vetted.

Again the issues were with the g19 sized mags and very much less so worth the 17/34 sized magazine.

Yes I agree other manufacturers have it figured out.

Yes it’s frustrating.

As others have said, glock designed the 43x and 48 to solve that “problem”.
Don’t like it? Carry Something else and focus your energy on moving weights or reading a book. It’s not going to be solved here unfortunately.

For LEOSA carry, bought three factory G17 mags, 10-rounders, thru Cabelas, in spring 2018. Report: They are 100% reliable with several brands of FMJ. So far, my Winchester 147 JHP has also been 100% reliable. The one thing I did deviate from is not topping off the mag after chambering a round. One in the pipe, nine in the mag. I figure why push my luck.

I pretty much do that with all of my Glock magazines for carry...

Yes, with the same caveats of the standard capacities.

It's the follower, replace the follower with the normal 9mm ones (I used 9mm3 when I lived in NY, there might be newer ones now), and all reliability problems go away. They redesigned the follower because it was maybe kinda sorta possible to sometimes fit an 11th round in some of the 10 round magazines with the normal followers.

This is 100% of the problem, I had no issues in thousands of rounds through 6 10 rounders once the proven follower was installed.

I swapped the followers in mine and I had mixed results. Some worked better, some still sucked.

I have two of them at home. I’ll check when I get home from work. I believe they came with the 9mm6 followers.

Don’t worry about it. I have some. I’m just wondering if the Co census is that they’ve fixed the issue.

Hahaha! Likely not the 48 but the 19 is possible.

Alright, so I’m completely full of crap. My Gen5 10-round mags have the 2184 followers in them. Looking at the top of the magazine opening, it looks like the nose end, right side of the opening needs some filing down.

I might be ordering a couple followers and grabbing some sandpaper here soon.
