ah I see, although the germans under the geneva convention are forbidden from using hollowpoint ammo plus the nato stuff is actually more powerful than the normal 9mm velocity wise, but even thats had reported failures to stop

but its jut hard to fathom that a 9mm would bounce off just like that, I mean its a pistol cartridge not a bb gun round and with a hollowpoint no less, although honestly even my father told me that back in the day he was shooting at one of those glass coke bottles with a .38 special sitting on a fence and it actually bounced off of it and came back at him, not hitting him but close.

I dont know I just like the 9mm round (and the .38 special) as its what I learned to shoot on so its just kinda hard to think of it as underpowered.
