    THUMB REST

    Posted by ARNE JOHNSON on 19th May 2025

    Nobody really needs a thumb rest on a 22 pistol but I got one anyway. Why? Because I use similar devices on my centerfire pistols. Why not train/plink with the same grip? Easy install thanks to video.

    Great Addition

    Posted by Nicky Michalares on 20th Apr 2025

    Really helped my shooting. I'm a newby after 40 year hiatus. Having a ball with 22's. When I was shooting as a kid, a box of 50 shells may last a year. This piece really helps my stabilization for keeping on target. This and the safety latch really add grip surface. Helped me increase my group size immediately. Not a bad install. If you've done the trigger, this'll be a snap.

    Perfect

    TK thumb ledge (gas pedal) was just the mod I was looking for and TK delivered a great product at a great price and bonus was the instructional video regarding install. My only wish… I wish they offered this in the good color.

    Gas Pedal

    i’m finishing up my Ruger 22/45 build and thought this would be a nice upgrade. I would highly suggest getting this thumb ledge along with the safety ledge for your pistol. This takes it to a high level of control for your pistol. It belongs on your pistol.
