Safety Thumb ledge
This "ledge" is quick to use especially drawing from a holster at Steel Challenge. My thumb naturally finds the safety and depresses as the gun comes to firing position. Very good design.

Safety Thumb Ledge
The Thumb Ledge works great, does the job, allows you to lock up and steady your hold on the 22/45. For me, it cut down on the shaking and wandering of the barrel. Well made and fine fit like all of the products I have gotten from TandemKross.

Must Have
No matter what shooting discipline I’m competing in I try to take as many variables as I can out of the equation so I can concentrate on the goal. For me the Ruger MK-IV 22/45 safety was too easy to accidentally engage with my right hand thumb joint as I brought the gun up. A helpful fellow competitor allowed me to try the Safety Thumb Ledge and I was instantly a fan. It eliminates any chance of an accidental safety engagement and it also provides solid feedback for engagement of the safety at the end of a string. 6-Stars!!!

Cornerstone Thumb Ledge
Great option for right handed users. This in conjunction with the Thumb Rest by Striplin Custom Guns gets you a great consistent grip for improved accuracy.

Safety thumb ledge
I paired this with their thumb rest and what a difference it made to my hand grip. Allows gun to be more stable in managing recoil and transitions. Installation is easy as per instructions. Great product.

Comfortable
This gives an actual comfortable place for your thumb to sit especially if you have larger hands. Now I don't feel like the safety is in the way of my grip. Had an issue with the first one I received but TK resolved the issue quickly and a replacement was sent.

Safety Thumb Ledge
This Cornerstone Safety Thumb Ledge is very comfortable as a thumb rest and feels like it provides added stability on the grip. It does not have an audible click when toggling the safety on & off and feels a bit mushy though. Flipping it up into safe mode with the thumb from the bottom side of the ledge is not as comfortable or easy as I expected. Also, gripping with the thumb under the safety is no longer an option, but then again it does precisely what it's designed to do which is for the thumb to comfortably ride the safety. Overall, I'm very glad to have this upgrade on my pistol!
