it is very hard to shake of some of the rifle habbits. cocking in the M16 is much easier, and im use to applying a certain ammount of force in a very certain way. in 9mm pistol its very duffrent, so i had some stopages from being half-cocked. on the other hand my military training makes me automatically tap the magazine in and recock hard, so stopages in auto weapons are usually solved very quickly...
