Description

This is a factory Glock 21 10-round magazine, chambered in .45 ACP.

Blocked at 10 rounds, this magazine is compliant with all local and State magazine capacity laws, such as California, New York, and others.

Featuring a steel-lined polymer construction, this magazine will endure and perform in the most extreme conditions. In addition, this Glock 21 10-round magazine features an anti-tilt polymer follower, precision-wound steel spring, and rear-facing witness holes. 

Some factory Glock magazine springs may be tight right out of the box. However, it helps to fully load the mag and let it sit for a few days.

Flawless Performance

I had the opportunity to fire my Glock .45 cal. with the new 10 round magazines which I purchased from the Magshack. I utilized all three magazines at full capacity and performance was flawless.

Exactly as expected

This magazine arrived as expected and in good condition.

This appears to be an OEM magazine & works well with the weapon. I haven't yet taken it to the range, but all other basic functions are fine: e.g. locks in securely, feeds ammo fine when manually cycling the weapon, follower engages the slide stop, drops easily from the mag release, etc.

I live in Illinois, which might soon pass a ban on so-called "high capacity" magazines (having capacity > 10 rounds). So, I'm getting (at least) one 10-rnd mag per weapon for temporary compliance until the law is challenged & struck down for being unconstitutional.
