Some re[ease agent on the grip frame and some silicone caulk to fill the voids would give you a non moving grip with a precision fit. Do one grip at a time and let it set up. I like Pachmayers or Hogues on my guns as they work well for me. I look at my guns as tools and pretty is as pretty does and they look good to me. Just wish Pachmayer or Hogue made grips for a Bisley grip frame. I would buy the first one they made.
