I really like the 22TCM round and have come up with some pretty good hand loads for it! I'm more of 1911 guy so I'm NOT interested in the conversion kits for Glock (mainly because those are all geared toward the shorter 9R round). The gun I currently own is the full size .22TCM/9mm Tac Ultra w/rail and is all steel and weighs a ton! I want to make a "Commander" sized pistol like the one currently offered by Rock Island Arms but with a high quality aluminum frame to reduce weight. I've already got a slide and frame and just need the barrel. If someone out there has 4.25" 22 TCM barrel that uses a bushing (not the bull) I want it!
