TheColt Ace orColt Service Model Ace is a ColtModel 1911-derivedsemi-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-recoilsub-caliber training while maintaining the feel of the military Model 1911 pistol.
Thesub-caliber Colt Ace was derived from the powerful.45 ACP chamberedColt 1911 to allow military, police, or civilian shooters to train with the Ace without the recoil and expense of the 1911, but with similar ergonomics and sighting. Chambered for the far less powerful.22 LR cartridge, its barrel was constructed (on all but the earliest models) with a hingedfloating rear chamber that amplifies the recoil when cycling the heavy slide,[2] giving it more of the feel of the larger, heavier weapon.
