a few of the old school 9mm pistols with problems
Egyptian HELWAN , the safety would engage while firing, mag release would work itself loose from recoil
WW2 German P38 , first time I test fired , it jammed, and sometime it would fire all rds with one pull of the trigger, had to take it back to gun store and they had it fixed
slide cracked all the way through, ruining an all matching pistol, using standard factory ammo. (yes I had new recoil springs)
a GLOCK is a much better choice if you plan to actually use it for HD or carry piece
