the 9MM(9x19) is a "pistol" round, you see there was this dude named Luger ...
it is also used in other guns that are not pistols ...
same round different guns, nobody calls it a 9mm SMG round when it comes out of a MP5 or an Uzi ...
fyi there are also other "9mm" rounds that range from 9x17ish to 9x30ish ...
mostly also called "pistol" rounds whatever they are fired out of ...
of course the OP could just clear this all up ...
No. The important noun is PISTOL...
9mm rounds from rifles are light years ahead of 9mm PISTOLS (as in the subject line) and the talk was of a person shooting a 9mm pistol round at planes....
which implies USING a pistol!
(*how's that for obvious, Strip? *)
