Marvel Precision Unit 1 .22 Conversion Unit
This was a much anticipated purchase and to say I'm happy would be an extreme understatement. This .22 Conversion Unit is an absolute tack driver. I opted for Marvel's steel slide lock-back, but they offer several variations with iron sights or a weaver rail (or both) and non lock-back versions. The included test target button shows the barrel shot a 5 shot 50 yard group of .567". I've tried the Marvel unit on several 1911 frames that I own and it works flawlessly on all. It's currently mounted on a Norinco M1911-A1 frame and I've added a Vortex Venom reflex red dot to the weaver rail. I've owned it for just over 2 months and have put about 1K rounds through it and it's a pleasure to use and extremely accurate.
