I've got a Llama 22 revolver with a pinned barrel(like a Smith), adjustable sights and a 6" barrel but would like to change grips. Do these share the same grip frame profile as a Smith & Wesson K22? If not, would any other Smith be the same? I was thinking about making an oversized pair of grips but would rather buy a set. Anyone have any information to share? The thing shoots just great and for $100, I couldn't go wrong. The finish is like new but those grips are just a little small.
