    Right Location

    Thumb rest position is exactly where my left thumb was. Now it gives me a more solid feel. Along with the TK extended safety they make my Ruger Mark IV 22/45 target feel like my CZShadow 2. Ideal for Steel Challenge.

    Striplin Thumb Rest

    This is a really neat accessory. When I shoot a Mark IV, I have a problem where the base of my left (suppport) hand thumb comes into contact with the bolt release lever. This device not only gives my thumb a natural resting point, it keeps the base of my thumb off the bolt release by moving it away from the gun itself.

    The thumb rest provides an excellent platform to aid in keeping the weapon on target for very fast repeat shots.

    When combined with the cornerstone ledge safety, this thumb rest greatly improved the stability and steadiness of my grip . My shooting improved immediately as it aids in consistency of grip and accuracy.

    Product is made great. Installation is easier then easy. Personally I just couldn’t get use to it, but that’s just me. Still will give it 5 stars
