I'm relatively new here, and I don't mean to offend anyone if they are a "stock only" sort, but I'd seen a good deal of threads here discussing just this. These threads actually lead me to the product itself, a .460 Rowland conversion for the Glock 21 found on 460rowland.com. I have been giving it a great deal of though, and tried to fish around to see what others thought of the idea, but I thought I'd pop in here, since I'd be more than willing to be you folks are more knowledgeable about glocks and their tolerances. So, the situation at current is this: I recently purchased a Glock 21, Gen 3. I decided to turn it into a project gun, of sorts. Its currently entirely stock, but I plan to order the aforementioned kit. Has anyone here tried it? Know someone who has tried it? Know if its a bad idea or a good idea? Thanks in advance, for anyone who took the time to read, and especially answer.
