I bought one for my Buckmark and haven't installed it yet. I put the Pac Lite 8 incher from TS on my Ruger MKII and love it. When I let a Bullseye shooter that competes with Rugers shoot it he was blown away by the light weight! I may buy a 22/45 just to get the lightweight grip frame for the Pac Lite barrel. I liked it so much I bought one for a Buckmark before I even had a Buckmark because I heard they were going to be discontinued.
