Aftermarket Glock magazines

I think “range only mag,” is code for “I made a bad purchase and I can’t admit it to myself.”

This 100%..

I have about 20 MagPul Glock 19 and 26 magazines. I've used them for several classes and all my range use for the last 4 years with no malfunctions. The only issue I've had is that the 26 magazines tend not to drop free.

For carry I use only OEM magazines

Does anyone actually see Glock OEM mags "wear out"? My oldest ones are a couple decades old now. Bought them when I bought one of my PCC's that use them. It has burned through untold cases of ammo by now to where I could not even count. I just do not ever see one of these mags actually stop working. Only time I have ever seen any mag from any maker "die" it was easy to see the spring was bad from the beginning. That is assuming no one stepped on the thing or ran it over and such.
Now I understand at times when there is panic shortage people grab what they can find but, am I the odd man out here that my Glock mags just do not stop working after time and hard use??

The only magazine of any kind that I've ever seen "wear out" was a USGI 1911 magazine that came with a used RIA 1911 I bought at a gun show. I have no idea how old the magazine was, I assume it was made before 1990 and it failed in 2007.

Factory or Magpul worked great for me and my 2 sons(total of 7 Glocks)..2 ProMag-piles of___..threw them away. Springs kept getting stuck down and no amount of takeapart and futzing would fix them..

I heard there were some issues with both Magpul and ETS mags early on. Both companies were responsive and product improved their mags.
This 20rd ETS has worked great. Nice size, too.

I just picked up 4 of the 40S&W 31rders from RWB to shoot in my G18. I'll be hitting the range with them this week so I'll post how they perform. For the price they were worth a shot.

Had a very good range experience with those RWB mags indicated above. They loaded properly, functioned flawlessly and overall I was very happy with them. They even kept up feeding a fully automatic G18 in 40 S&W. For $18 a piece you can’t go wrong.

I have a jagemag, worked flawless for me for the little bit i had it. Ended up selling it when i sold the 3rd gen 29 i had.

The only thing I'll do with any of my twenty or so GLOCK mags is recharge the ones in regular rotation with Wolff extra-power springs every few years. It may be overkill, but they work and work and work. I do mark every mag differently so I can ID any that may ever have an issue and rotate that one out.

I soured on P-mags when we had a few of their AR mags split at the seam in our M-4's. I know they've updated and brought out a lot of new stuff that folks seem to like, but for a GLOCK (And the AR) I just didn't see another reason to swap out from something that works as-is.

I did buy a couple of 33-round aftermarket GLOCK mags for the PC carbine, one has worked well and the other not so much. The two factory 33-rounders I also bought have been 100% so far.

If you want to experiment and then find stuff that works well for you, go ahead and give it a whorl. No original manufacturer has all the answers and there is some stuff out there that can be a great improvement.

Stay safe.

KCI and Magpul are good.

I've been using the same lot of around 20 17 round KCI mags as practice mags, every week, for a little over 10 years now, and would trust them enough to use them for carry. They work fine, and are half the cost of factory mags.

I did have trouble with their 33 round mags though and dont recommend them. I've also had troubles with the factory 33 rounders, and haven't been happy with them either.

I have a number of Magpul mags as well, and they seem to work as well as the KCI's. Their 27 round mags work flawlessly too, as do the 21 and 17 round mags.

Same here would add I have had one G 27 mag split is was a factory mag.

The Korean specials work just fine in my PCCs.

For extended mags, even the factory 33s arn't 100%. There's a reason purpose made subgun mags are double stack/double feed.

I've had problems with the KCI mags. I wasn't able to load them to capacity at first, and just loading and unloading mine, they don't feel like the real Glock mags. I have had double feeds with the KCI 33rd magazine.

It took a while for them to break in. I'm able to load them to capacity now and I haven't had a problem with them in a long while but they're range-use only.

I have two aftermarket brands in my Glock magazine rotation. One is an extended ETS mag for the G43. It's an invaluable training tool for when I want to practice clearing double feed malfunctions without having to manually induce them. The other two are Shield S15 mags for my G48/43x. No problems in 500 rounds.

The Shield mags have made my G48 my favorite carry gun.

I have about half a dozen KCI G17 mags and the same amount of KCI G19 and haven't had any problems out of them and they have been shot extensively over the last few years by myself and two others in my three Glocks and G17 and G19 style Poly 80's. I have two of the KCI 33 rounders that I use in my Micro Roni and it has been at least 98% reliable for the last two years.

I got a Korean 50 round drum magazine. No last round holdover, but thats fine.

So far it's fed 150 rounds without a failure. If it makes it to a thousand I'm applying more graphite and doing another 100 then using it for home defense. Im satisfied with it so far for sure.

Glock makes factory 33 rd Mags. Got one last week

Us Glock owners are lucky that there is at least 1 good aftermarket magazine choice (IMHO, Magpul) for the 17, 19, and 26.

I was offered a free ProMag for my Sig P6 (W.German police version of the original P225). This magazine actually worked fine when I tried it, but it wouldn’t drop free, but some magazines are designed that way.. The OEM’s all drop free. I declined the offer, and was able to scrounge 4 more OEM mags at a fair price, which is becoming really hard to do, I now have 7 OEM magazines for this gun

Friends don’t give friends ProMag magazines. A ProMag magazine is what you give someone that you want to de-friend.

Used the Magpul ones quite a bit and they have always worked fine.

Haven't used any of the others.

OEM and Magpul mags have both worked well in my Glocks

Beat me to it. I was going to say the same thing.

I don't have a dog in this fight since the only Glock I currently own is the G44 and I have yet to see any aftermarket magazines for it yet. Once I get a G19, I might try magazines from Magpul, KCI or ETS. I played the aftermarket magazine games with my 1911's and pretty much just stick with OEM, Colt or Mec-Gar magazines.

I have had excellent results from Kahn, KCI and ETS. I bought several PW 33 rd mags many years ago. Some worked well, but others did not. I would not hesitate to try Magpul based on the good results I have had with their AR mags. And yes, Glock OEM mags are excellent.

When I was downrange as a PSYOPer part of me thought it would be funny to airdrop ProMags for the Taliban to use. The malfunctions might have saved American lives.

OEM GLOCK, or go home.
