BudsGunShop.com - 10 Round vs 15 Round

Ken, yes sir, this will fit and function just fine in a 15 round Glock 19. This is the same size as the 15 round version magazine. It's just pinned for magazine capacity restricted states. Hope this helps.

Ken, yes Sir. Most manufacturers including Glock make 10rd magazine packages so their firearms can be sold in States with magazine capacity restrictions. The only difference is the magazine (10rd) compared to the standard model package 15rd magazines. The firearm will accept either capacity magazine. Cheers and stay safe!
