Does anyone here have any experience with any of the 1911 conversions? Specifically the Tactical Solutions 2211 slide (all steel & adjustable sights)? Or the newly released Rock Island XT22 (a 1911 frame with fixed sights and a special cut steel .22 slide) Or the 85% size Browning 1911-22 (aluminum frame and slide, plastic grips, crappy sights, and plastic guide rod). Smaller one on bottom: I have my next .22 purchase down to one of these setups. I want a dedicated .22 in a 1911 setup. I've already had the Ruger 22/45 and that didn't satisfy me. I've read a lot of mixed reviews using google to search, but I am hungry for more! The Rock Island seems to answer all prayers at only $450, but it needs a 40gr bullet for the slide to work properly if I have read most reviews correctly. The Browning is $550 and aluminum, but eats any bullet I've read. Not to crazy about the aluminum and price though. And the Tactical Solutions will require me to spend $300 for a used one and another $300 for a complete lower 1911 frame (since I want it dedicated). I've kinda answered my own question, but I want to find a reason that spending more $$$ is better I guess lol.
