A fellow shooter let me try his Ruger MK IV 22 45 with the Accelerator Forward Thumb Ledge. I liked it so much I ordered one for my Ruger MK IV 22 45. It gives you a feeling of added stability and confidence in your ability to hit what you’re aiming at and my groupings improved. I will be shooting steel challenge with this pistol, I feel the addition of the accelerator forward thumb rest will help with the transition between the targets and lead to improved scores.

Easy installation. Just follow the video instructions. Works great.

Great aid for your gun grip. Made my grip more comfortable and steadied it further, IMO. Watch the video at least once to get familiar with the install. Note: Install Video is below Thumb Ledge Website description on TK's Website. The Video Title is a little misleading as it says: " Muzzle Rise " with small print at the top that starts " Install & OV ...." and is cutoff. The install is further along in the video. TK's other video for their " Titan Extended Magazine Release for Ruger Mark IV 22/45 " Does state: "Install Instructions" (with a red banner in the title).

This is a great addition to any MKIV 22/45! Incredibly easy install and makes the gun have a much better fit in your hands.

Another quality TK product ! Was a bit wary of the size of the thumb ledge as it looked a little large but I figured I could easily trim it to my taste. But after having installed the Accelerator it feels fantastic. Now I really wish I could checker the front of the trigger guard!!?? One note: I have a Victory trigger that I had adjusted for pre-travel. I found I had to readjust the pre-travel screw after the Accelerator installation; only about 1/8 of a turn as the trigger wasn’t resetting reliably. Otherwise, I love the fit/feel and it gives me a rock solid grip! Very highly recommend it and it’s well worth the price!

Well made! Installation was straightforward and the shooting grip is improved. Worth the price.

As with all the TANDEMKROSS stuff I’ve purchased this item is great. Only bad thing is it’s a little tricky to install keeping everything lined up. I will also add if you have the holster I purchased from TANDEMKROSS you will have to modify it to clear the thumb rest (gas peddle). It really does help give you the perfect grip and after a while of using it your brain should make you transfer that learned position to your other pistols that don’t have a gas peddle.

Great product. Easy to install. Works great on the range. This is a great way to train your hands positioning .

This product precisely meets my requirements for enhancing my Ruger Mark IV Lite. The installation process was remarkably swift and straightforward. The thumb ledge is aesthetically pleasing and performs as anticipated. I intend to incorporate this feature into other pistols as well. The shipping process was also expedient.
