It was May of 2017 when I published the review of the then new Ruger MK IV 22/45 Lite, you can read that review by following this link. A few weeks later I upgraded some of the factory parts with Tandemkross parts. You can read that full review by following this link.
The Cornerstone safety thumb ledge allows you to run a high grip on the 22/45 riding your thumb on the safety ledge for solid control.

The Hivegrips are textured wrap around rubber grips with finger grooves that aid in keeping a solid purchase on the pistol, especially when your hands get a bit sweaty after a long day at the range.

I have come to know a bit about Tandemkross and they make quality aftermarket parts for several platforms, so if you are looking to upgrade your match or range gun it would be worth checking out their website and looking over what they have to offer. https://www.tandemkross.com/
