"Cornerstone" safety thumb ledge
I thought my Ruger Mark IV 22/45 lite was a fantastic, nearly perfect 22lr pistol for fun on the range, until I got it in my hands. Boy, was there a real problem with the pistol, the safety. It was clumsy and awkward, ill-conceived in design and took away a great deal of pleasure from an otherwise almost perfect firearm for me. But wait! Tandemkross comes to the rescue with the new "Cornerstone" safety thumb ledge. What a difference this has made to the ergonomics for this pistol! If you are an owner of a Ruger Mark IV 22/45 lite, this is a "must do" modification to your pistol in my opinion. Beleive me, this improves the feel and function of the pistol beyond any other simple mod that can be done to it. Ruger should take note of the Cornerstone safety thumb ledge in their next design change for the Ruger 22/45 line of pistols.

Good Could be better.
Great replacement if the factory safety switch got destroyed while trying to remove the ambi safety ,due to a stripped screw, only complaints is the edges are a little to fine ,imagine your thumb is a little kids head running into the corner of a table, my thumb has a little skin missing now from cycling the safety trying to get the ambi safety washer to the perfect tightness , is the washer supposed to be able to spin is it supposed to be tight but not to tight , like what does that mean, all I know is it’s great for what it is , ,

Super comfortable compared to stock safety. I have large hands and stock safety was annoying to me. Another great upgrade from TK!
