About the Gun

In an effort to fulfill the need for 1911 pistols during World War II unconventional companies were contracted to produce the handguns. Union Switch & Signal was one of those countries. The company primarily made railroad signaling equipment but received a contract in 1942 to produce 200,000 1911's. Only 55,000 U.S.&S. pistols ended up being produced, making them the second rarest of the WWII era M1911A1 pistols.

About the Cartridge

This cartridge was developed by John Browning and was adopted by the United States Ordnance Department along with the Colt-Browning automatic pistol in 1911. It has also been made the official military handgun chambering by several other governments, notably Argentina, Mexico and Norway. The 45 Automatic is the most powerful military handgun cartridge in use today. This is a heavy and powerful sub-sonic round. Although its muzzle energy can exceed 400 ft-lbs, its velocity and bullet weight creates a steep trajectory curve that limits its effective range to self-defense distances.
