About the Gun

Armscor's TCM series of pistols are functionally a 1911 series-70 pistol design but chambered for their unique .22 TCM cartridge. Since the .22 TCM is essentially a stepped-down 9mm cartridge, the gun can fire 9mm rounds from the same magazine by simply replacing the barrel and recoil spring. Armscor ships both .22 TCM and 9mm barrels and springs with each TCM pistol. The TCM series includes both single-stack 10-round models and double-stack 17-round models.

Analysis

This .22 caliber pistol offers a compelling package for shooters seeking a unique blend of performance and design. Its accuracy is noteworthy, delivering tight groupings at moderate ranges, which makes it suitable for both casual plinking and competitive shooting. The ergonomics are well-thought-out, with a grip that accommodates a variety of hand sizes, ensuring comfort during extended sessions. Reliability is generally solid, with consistent feeding and ejection in most conditions. However, maintenance can be somewhat demanding, as the design requires meticulous cleaning to prevent malfunctions. Availability of replacement parts may also pose a challenge, potentially frustrating owners in need of repairs. The trigger pull is crisp, averaging around 4-5 pounds, which aids precision. Felt recoil is minimal, making it approachable for newer shooters, though some may find the high-velocity round’s report unexpectedly sharp. Overall, it’s a capable choice with specific considerations for upkeep.
