Glock Factory Original Magazine For Glock 21 .45 ACP 13 rds is rated 5.0 out of 5 by 12.
Rated 5 out of 5 by from Glock 21 Mag. Had just bought a Glock 21SF for use in the concealed carry classes that I teach for the state of Oklahoma. Wanted to have on hand more than two mags, which came with the Glock. So, I began looking at local vendors with no luck. I began looking on line and ran across your site. I ordered two mags, expecting them to be aftermarket off brand stuff. I was surprised to find real Glock mags in the box when I opened it up. I will continue to order other items as needed from your site. Thanks for supplying real brand name products. Unlike other places that use a stock photo of real items, and then switch out aftermarket. Semper Fi. OUT!!!!! 'Nam Vet.

Rated 5 out of 5 by from Just the mags I needed for my Glock 45 21sf I'm very pleased with the Mags. They arrived a couple days after my purchase. The price was well below all the others I've looked at. I definitely will be ordering more products from the catalogue that was shipped with the Glock 45 21sf mags.
