:cb2: Here's yet another endorcement for the EABCO Tri-Force mount. Brown put a scope mount on a Ruger Bisley for me years ago, and I couldn't be happier with their work. They used larger than normal screws for more contact area with a stronger, better hold. I sent them my scope along with the gun, and they mounted it for me. Fine people, excellent work, and well worth the price.
