if you doin a drive by, at least a fully automatic with a magizine that takes alot of rounds....
if you packin for protection... then a hand pistol would be good enough, .380 , 9 or .40 cal
if you wanna plot out a murder get a revoler.. leaves no casing to pick up...
or a .25 at a close range... ( the bang won't be that loud )
if you goin 2 war or robbin a bank.. u better have a major heat like a ak 47, m16, ar-15 and all that big shit.
