Hmmmmmm. When the M16 was introduced into the army of my country in the 70s ( if I remember correctly ) the scepticism we held towards the tiddly little bullets ( we used .308 SLRs then, and they really did put people down ) was countered by “them” telling us they tumbled in the air and would rip up anyone they hit.
Not that I ever found out if it was true myself.
Whatever, hitting a moving target with a hand gun is not as easy as the movies would have us believe. I would certainly like as many bullets as possible in the magazine.
