Have purchased several Tandemkross products and find them well made and good value. Had a bit of a problem with the cornerstone.. It happens.. Tandemkross quickly resolved the issue. Excellent products that they support with professionalism. I m a fan.

Very comfortable
Big upgrade from the stock safety lever which dug into my hand while shooting

Great Addition
Purchased and installed the Cornerstone safety. Video was succinct and easy to follow. (BTW, Bill is great in the videos.) Great replacement for factory safety. Functions as expected, as all Tandem Ruger parts. Gloss black finish is fine. Only wish is that would be available in flat or parkerized black.

Cornerstone for 22/45
This is a must have addition to your Ruger 22/45. I had a problem with nudging the safety up with my thumb and the Cornerstone remedied this as well as providing a stable location for the thumb. if you shoot steel get one. Fit and finish is superb and installation is easy.

Thumb safety
I very much like the concept (all my 1911s have larger thumb safeties). Even with my thumb riding the Cornerstone safety, it has a tendency to flip on in the middle of a course of fire. This seems to be some combination of where the safety contacts the base of my thumb and the recoil. I talked with another shooter who had the same problem but I m not sure how to fix it. Doesn t happen with the stock safety.
