FROM WIKIPEDIA
The Colt Ace or Colt Service Model Ace is a Colt Model 1911-derived semi-automatic firearm chambered for the .22 Long Rifle cartridge instead of .45 ACP. It was created in 1931 and produced through 1947 to allow inexpensive and low-recoil sub-caliber training while maintaining the feel of the military Model 1911 pistol.
