“You can get ridiculous,mis-feed-waiting-to-happen capacity mags for both.”
Not limited to the ar15 or glock.....
the m1a1 would do the same thing.... on a cheapie 30-round mag that little lift inside would stick partway up :(
Seriously though, I'll stick with 30 round Magpuls PMAGs for the AR and factory 15 round Glock mags for the G19. Ok, I do have some KCI mags for the Glock on order, but due to mixed reviews I'm only figuring to use these at the range. The hollow point self defense rounds will stay in the factory mags.
