M1911A1

The M1911A1 is a semi-automatic handgun used by Naked Snake during the Virtuous Mission and Operation Snake Eater. It was used extensively from World War I through the Vietnam War.

Being a relatively small gun, the M1911 can held in the right hand while used with a knife in the left to perform CQC, a form of close-quarters combat developed by Snake and The Boss that was imperative for Snake's missions.

Naked Snake had a M1911 during the Virtuous Mission, but it was disassembled and tossed off a bridge by the Boss. When Snake met EVA in Rassvet, she provided him with a similar gun. It was revealed that Snake used a custom grip in order to hold the knife and gun with both hands.
