No Drill Grip Mount for a Ruger Mark I/II Pistol. It would also fit a Mark III. The advantage is that you can still use your open sights when installed. It is good if you would like to keep your open sights functional, and occasionally use a red-dot, and not have to drill into your Mark I/II receiver. With the light recoil of a 22, it functioned fine on my Mark II before I installed a Mark III type mount for Bullseye. It is black aluminum with 98% finish. $15; Adrian Kibler, Email kiblerae@cox.net, Phone: (757) 547-4017 (H); (757) 535-0111 (C); No calls after 8 pm please.
