M9

beretta M9 9mm semi-auto pistol, a peice of shit,..
a peice of metal, useless for the most part, more deadly when thrown then when fired, (or when attemping to fire anyway,...)

i pulled te trigger, but nothing happened so i threw my M9 at the bad guy and dropped him in his tracks

M9

Beretta 92FS 9mm semiautomatic pistol as adopted by the armed forces of the United States. Probably the sexiest gun of any type ever made.

My M4 burped on a whole shitload of sand, so I whipped out my M9 and continued engaging the bad guys with it.

m9

When a newb tries to be a smart arse when calling you mate abbreviated as m9 instead of m8 just to piss you off. More commonly when playing an FPS such as Battlefield or CoD.

Newb: "Nah blow them up m9"

Veteran: "Nah f*ck off m8"
