I hate to be a "can I do this?, can I do that?" and divert the main subject but I guess I'll ask a "can I do?". I recently purchased a CR-45LC and I was wondering if barrels can be fitted to this frame as simply as any other SB2 frame. I'd like to get a 30-30 barrel for it. If I could find one that doesn't get snatched up quickly, I'd buy it but for some reason, I think it might be quicker to just send the thing in and have a new one fitted (if the factory fits one to this frame). The real question I'm asking however, is how much work is entailed with fitting a second barrel to a frame? Is it something an "average Joe" could do?
