Bryant Ridge's Analysis:
The Colt Ace began life in 1931 as a full-size .22 LR semi-automatic pistol modeled closely on the M1911, utilizing the same frame dimensions, grip shape, and general ergonomics. It was intended to provide shooters with a low-recoil, inexpensive trainer that retained the feel of a full-bore service pistol. Early production used a straight blowback action, and these “Pre-War Ace” pistols often suffered from unreliable cycling because the .22 LR cartridge sometimes lacked the power to move the heavy 1911-style slide reliably. Recognizing this limitation, around 1937, Colt, working with designer David Marshall Williams, introduced the “Service Model Ace,” which used Williams’ floating-chamber design. This internal moving chamber used gas pressure from the fired .22 LR round to impart additional rearward force on the slide, improving cycling reliability and giving a felt recoil closer to a .45. As a result, the Service Model Ace became far more practical for training — both for military and civilian shooters — and was reportedly used in some early U.S. military marksmanship programs. Production of the Ace line (original and Service Model) continued through World War II, with pre-war Service Model Ace serial numbers recorded up to approximately SM13803. While total output was modest, the pistol left a lasting legacy.

Decades later, in 1978, Colt revived the design as the Post-War Service Model Ace, which remained in production until 1982. These post-war Aces retained the same basic specifications as the pre-war models, were most commonly finished in blue with a rarer electroless-nickel Custom Shop option, and carried “SM” serial number prefixes. Some post-war examples may exhibit additional markings; however, verified documentation for variants such as a “B70” suffix is limited. Today, both the pre-war and post-war Service Model Ace are prized by collectors for their innovative floating-chamber design and their role as authentic 1911-pattern rimfire training pistols.
