Well made! watch the installation video. - TANDEMKROSS Cornerstone Safety Thumb Ledge for Ruger

I feel like I have more Tandemcroos on my Ruger then I do Ruger parts :). I highly recommend watching the video a couple times before the install. I messed up by tightening up the screw, that holds it in place, too tight. I rewatched the video and discovered my mistake. Works perfect now.
