Our Assessment: The 1911 and 1911-A1 pistols served the military of the United States from 1911 to 1985, through two World Wars and the Korean and Vietnam wars. They gained a reputation as a reliable handgun with plenty of stopping power, and are held in high regard by those who have used them. Yet it could be expensive to train thousands of soldiers to use the 1911 while feeding it .45 ACP, moreso at the outset of WWII when the US Military would see the greatest expansion in its history. The Colt Ace had been introduced in 1931 as a .22 Long Rifle version of their Government Model, but it was dimensionally different and had significantly less recoil than the real thing. David “Carbine” Williams adapted his floating-chamber design to intentionally increase the recoil of the .22 LR cartridge to the point that it was similar to that of .45 ACP, even allowing the use of the same recoil spring. This became the Service Model Ace and allowed for drastically reduced practice costs when training GIs to use their 1911s. The model was discontinued at the close of WWII, but was reintroduced by Colt in 1977. It was chosen for the Colt Signature Series in 1981 to celebrate the man who gave his name to Colt’s Patent Fire Arms Manufacturing Company. Built by the Colt Custom Shop, this is a gorgeous specimen of a Service Model Ace, sure to take a prized place in a Colt collection. Please see our photos and good luck!
