okay, what would you have liked to have used in the Second world war out of these or something else if this list is not statisfactory for you.More input needed, bump.
M1911. For close in work, it had the stopping power and was tremendously reliable.
A tie between the Browning Hi-Power and the Walther P38, both are rugged simple designs chambered in 9mm Luger and are still in use with military and police forces all over the world. The M1911 may have more stopping power, but in a warzone it's in your interests to wound the enemy rather than kill him because a wounded soldier takes up more of the enemy's time and resources than a dead one.
