    What a Improvement over the factory safety!

    Posted by Doug on 6th Aug 2024

    I struggled to manipulate the factory safety on my Mark IV 22/45 and did not need ambidextrous. Ordered the Cornerstone and what a difference. A solid rest for my right thumb and no doubt whether the safety was on or off! Great product and a breeze to install. Put a little VC3 on the screw to make sure it would not back out.

    Great Addition

    Posted by Ray Stroup on 5th Nov 2022

    Purchased and installed the Cornerstone safety. Video was succinct and easy to follow. (BTW, Bill is great in the videos.) Great replacement for factory safety. Functions as expected, as all Tandem Ruger parts. Gloss black finish is fine. Only wish is that would be available in flat or parkerized black.

    Cornerstone for 22/45

    Posted by Nicholas Brocato on 8th Jun 2022

    This is a must have addition to your Ruger 22/45. I had a problem with nudging the safety up with my thumb and the Cornerstone remedied this as well as providing a stable location for the thumb. if you shoot steel get one. Fit and finish is superb and installation is easy.
