Glock 17, Staccato HD P4 or Staccato HD P4.5 9mm 20 Round Magazine Mec-Gar MGG172003A

These Magazines have worked great in my Glock 32 with 9mm conversion barrel, my Glock 17L, Glock 45 and Glock 49 (of course they stick out of the shorter frame pistols but no problems, great function) I'm ordering more right now and mainly sticking to Mec-Gar for my Glocks now, like everything else I can use them in!
