Cornerstone Safety Thumb Ledge RugeR MKIV 22/45
Watch the installation videos before attempting this super upgrade. This is a very well thought out ergonomic Engineering Design. The red color really accentuates my black Tactical 22/45 MKIV.

Looks Nice
I got this to add some color to my red and black MK4. I shoot steel matches that require a reload and honestly this gets in the way. My thumb pushes the "Cornerstone" up a little when I release the slide and puts it on safe before my follow up shots. It looks great but and would work for target/plinking but not competition.

Great Upgrade
Great upgrade to the undersized stock safety switch on the Ruger. Very easy to install and feels great when gripping the pistol. Comfortable ledge for your thumb. Easy to switch on and off (safety)

Really like this safety it removed the the one on the other side of the pistol, an gives you a place to rest your thumb.

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.
