BTW, I actually like the Beretta M92 in 9MM. IMNVHO, it's the wimp NATO ammo issued by the military that could be the problem. Put some manly loads in the mag, and then we'll talk "lethality" ...whatever that is. Missed shots with the ole .45 (which I hear do happen) aren't very lethal, either.
Most people don’t shoot semi autos as well as they do revolvers...The more powerful the ammo, the bigger the difference. In my experience with Army shooters the M1911 should have had a bayonet lug.
