The Union Switch & Signal Co., manufactured 55,000 Model 1911A1 pistols during the single year of production, 1943. U.S. & S. pistols are very desirable in original condition.

Very fine. The pistol retains 85% plus of the original Du-Lite finish and has all of the original components. Most of the finish wear is concentrated on the grip strap, bottom of the trigger guard, mainspring housing and the edges of the receiver. The slide shows high point wear. The barrel retains 70% of the original blue finish. The stocks have moderate handling wear and are in very good condition. The magazine retains about 85% of the original blue finish. This is a very good example of an original condition Union Switch & Signal Model 1911A1 pistol.
