Colt 22 Conversion Unit 22 LR

Read Gun Tests Rating and Recommendation

The Colt is a good conversion, but in this case, we feel there are self-loading 22s in the 1911 format that are a better choice. This conversion is pricey, and there are good alternatives. Finding spare magazines is tough.

The Colt conversion is well finished and proved accurate. The Colt conversion is mounted on a WWII GI frame.
What looks like a two-piece barrel is a floating chamber. This was developed to allow good function with a steel slide versus an aluminum slide.
Left is a Colt magazine, which we found to be unavailable at the time of the test. Instead, we bought a GSG M-1911 22 LR 10-round magazine, right, $31, which offered some functionality in our conversion. This magazine may or may not function with your 1911 Colt conversion.
