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. This example was produced in 1942 and is in Fine condition with light operational and handling wear in its beautiful Colt blue finish. About 1,000 pistols later, the finish would be changed to a less appealing phosphate. This is a fantastic specimen of a Service Model Ace, especially with its box, tag and manual, sure to take a prized place in a Colt or US Military handgun collection.
