I just picked up a Glock 21 SF and I am looking to trade for some additional magazines. If you have 2 *NEW* Glock 21 magazines I can trade you two new Glock 17 magazines or 100 rounds of Federal .223 ammo. If you have two used Glock 21 magazines I can trade you two used Glock 17 magazines. If you happen to have some for sale at a decent price feel free to send me a PM. Thanks!

I know those magazines are hard to find now , I just bought a gen 3 21SF and my LGS Ultimate Arms LLC ordered me a spare . They said two weeks , everywhere I looked online was sold out with no backorder so there are some available try your local gun store or call mine maybe they will ship them or you could drive it's a little over an hour from orlando to Lakeland. good luck

I may be splitting hairs, and you may already be completely aware, but there is no difference between the regular and slim frame magazines.

I thought the slot for ambi magazine on the SF 21 gen 3 was slightly different than the gen 4 . I stand corrected but the 21 13 round magazine is very hard to find right now , I found 2 different part #'s one for SF and a different one for the 21 standard in my quest . good luck

As I go back and read the OP, I realize now I misunderstood what he was saying he was looking for. Sorry if I made this more confusing than it needed to be!

Earl, we are both correct - If you have an older G21SF with an ambidextrous mag release, the regular G21 mags will not work. Glock dropped the ambi mag release last year, and standard mags should work in the newest versions. It all depends on which mag release you have.

Speicher - sorry to have hijacked your classified! I only have standard G21 mags right now, but I am not particularly interested in selling them. I hope someone else will come along with what you need!
