This is one of the best Ruger® MKIV™ 22/45™ accessories for competition shooters. Get your "Cornerstone" today and lay the foundation for a better grip!
Please note: The "Cornerstone" installation utilizes a factory spacer included in your original box. This part is referenced on Page 23 of the original Ruger® manual. If you cannot located this spacer, please contact TANDEMKROSS or Ruger® and we can assist you with locating one.

Nice Safety Upgrade
I wish I was able to keep the ambidextrous safety on both sides but as a right hand shooter this is great. Finish looks great and resting on your thumbs on it lets you hug the frame real tight. I wish the angle was pitted down a little lower but overall very pleased with this product.

Great Upgrade
After purchasing the front thumb rest I just knew that I had to have this one as well, what a difference in control, especially on the Lite version of the Mark IV

Outstanding Item
I added this item to my Ruger 22/45 LITE. Such a great upgrade to the OEM thumb safety. Ruger SHOULD have used this as their stock safety. It was a bit of a bear to install however. It installs like the instructions show, but the internals move out of place just enough to stop you from pushing the new safety through easily. However, with a few colorful metaphors, I finally got it all to line up and installed. I love this item, and the company’s customer service is grrrrreat!!!!!
