Great addition to my shooter. Easy tofu d and activate. Only one con, if you don’t keep good hand placement and thumb on the ledge you can trip it into a half locked position. So easy to install even a teen age girl can do it :)

Underwhelming
The good: it feels better in the original safety and my thumb holds it down so it doesn’t come on by accident. The not so good: I don’t think think this is worth $60. I understand there’s design and machining involved but that seems really steep for what it adds. I’m super happy with my other TK stuff but this one misses the mark on value.

Works great!
Before installing the safety ledge, my thumb was kind of searching for a natural place to rest. Also, my thumb knuckle would sometimes bump the safety causing it to partially engage. With the safety thumb ledge installed, all of those issues are resolved; plus it looks cool!

GOOD TO GO
Does what it's supposed to. Much better control and feel. Will continue to buy from you. Also goes for other products on same order and previous orders.

Competition Shooter
This was one of the best add on to my Mark IV. It helps make sure the safety doesn't come on in the middle of a shoot and also gives a better grip on the gun. Shooting Steel Challenge, it's important to be able to take the safety off quickly for the first shot. I rest my thumb on the safety and it's just a quick flick to get it off and be on target. Add the thumb rest and you have a great combination

Great addon
I had no problem with stock safety.. but after shooting a gun with this mod of the safety... it was a no brainer. It makes the gun so much easier to shoot.

Comfortable and stylish
The Cornerstone thumb ledge is a great addition to my 22/45 Lite Ruger. It provides a Positive secure placement for the right thumb. Coupled with the "Hive" grip for the Ruger I feel you get and exceptional rock solid grip on the pistol with little or no effort. The ledge is a bit larger and feels so for a few rounds.. but the stability it offers in controlling the platform is outstanding. Good shooting to all. With different colors offered it really can set your pistol apart from the rest. Good shooting to all.Dave
