[ARCHIVED THREAD] - What's the lowdown on aftermarket, high capacity, Glock magazines?

Posted: 2/20/2017 1:29:29 PM EDT

I'd like to know if any of the Korean high capacity Glock magazines work reliably, or what problems they pose? I have a friend, overseas, who's looking to import an AR15 carbine in .40S&W that uses Glock mags, and he's asked me to do the research for him. It would be mostly a range gun, but he doesn't want to keep dealing with failure to feeds, etc.

So, what works, and where should I look for them?

Thanks in advance!

And you, in turn, ask others to do your research in a thread, rather than searching the internet for answers yourself ??

1st....go to google and bing.
2nd...when searching there, you can add ar15.com to the search, and you'll find threads here with info.

As far as aftermarket magazines go I've liked my ETS 22 rounders so far. My son's Korean 25 round .45 magazine has worked flawlessly.

Those ETS 22 rounders are actually 21 round magazines, so plan for that.

I hadn't even heard of the ETS...just looked them up. Do the KCIs have the metal liners like the factory Glock mags?

Thanks again!

ETS sucks with steel cased ammo or heavy brass rounds.

Same goes for Magpul.

I stick with OEM Glock mags for their steel inner lining.

Thanks. What's the problem, do they bulge and have problems going into the magwell, or is it feeding issues?

I'm a firm believer in factory mags, but in this case, it's solely a range gun, I believe he's looking at 31 rounds for the aftermarket (KCI?) vs. 22 rounds for factory. I guess if he doesn't mind an occasional hiccup he can always buy a few of each.

Thanks again for the feedback!

IIRC ETS was having friction issues with steel cased ammo. They seem to be gtg with brass though.

I ran a KCI 9mm hi cap in a G34, it ran fine BUT it bulged in the middle when full. Factory steel lined mags don't bulge.

You'll also find that some aftermarket mags that run fine in Glocks don't run as well in ARs that take Glock mags.

Personally I stick with the factory mags, except for an SGM .45cap hi cap mag since Glock doesn't make one. The SGMs seem to have stronger springs than KCIs.

I appreciate the continued feedback on this subject, guys.

A good weekend to all!

OEM Glock have been flawless.
