"Tomahawk" Hooked Magazine Bumper Installation Instructions


At a glance:

  • Oversized bumper improves the consistency of positive magazine seatings
  • Curved, hooked bumper offers ideal placement for pinky - great for shooters with large hands!
  • Improved hand placement boosts control and improves leverage for more accurate shooting


*Includes two base pads per order.*

The Ruger® Mark IV™  22/45™  has become a favorite rimfire pistol among competitive shooters, like the Ruger® Mark III 22/45™  and Ruger® Mark II 22/45™  before it. But the flush surface on the magazine base pads of these 22/45™ pistols can be challenging for competitors, making it harder to consistently seat the magazine properly and causing unnecessary delays.

The TANDEMKROSS Tomahawk Hooked Bumper for Ruger® Mark IV™ 22/45™ (2-Pack) offers an oversized, textured Zytel® grip, allowing the user to easily bump the magazine into place for positive, consistent magazine seatings. The curved, hooked Ruger® magazine bumper offers an ideal placement for the user's pinky, boosting control and leverage over the pistol - perfect for shooters with large hands and competition shooters looking for a better grip.

These drop-in Ruger® magazine bumpers attach to the bottom of the factory magazine without any glue or gunsmithing - installing in minutes! This simple Ruger® 22/45™  upgrade is ideal for competitive speed shooters or any Ruger® owner looking to improve the firearm’s reliability.

    Nice update to the 22/45

    Posted by Rick Jerothe on 19th Sep 2022

    Looking for items to trick out my recent 22/45 addition I ran across these bumpers. While the unique form of these caught my eye the function of them while firing the weapon really surprised me. The added hook of the bumper provides for a nice placement of your lower finger on the grip ensuring a consistent placement of your hand while upholstering.

    Great Look and Function

    Posted by Storm Shriver on 7th Jul 2022

    The final product looks awesome and also gives the pinky a place to rest while shooting. The only reason I took off a star is because this basically needs a second person to install correctly. There is a manufacturer small circle on it where the pin will lodge into before it hits the right spot. I had another person us a small flat head screwdriver to push the pin down while I slid on the bumper past that point and then had them remove the screwdriver. After that it went on perfectly. Instructions could be a little more clear in this instance. Otherwise great product!

    Tomahawk Hooked Mag Bumpers

    Posted by Mike on 9th Jan 2022

    I personally bought (6) of the 2 packs of Tomahawk Hooked Magazine Bumpers for Ruger s MKIV 22/45 Single Stack 10 round magazines, and I am % Happy with my purchase! These Tomahawk Hooked mag bumpers definitely Complete the Look of my Custom Ruger MKIV 22/45 Lite/ Volquartsen/ Tandemkross s The Kraken Pistol Build and they definitely help when using a 2 handed grip, as well as with making sure you ve positively seated your magazines on reloads, plus they also help when ejecting spent mags so reloads can be quicker and more efficient. I love Tandemkross s Tomahawk Hooked Mag Bumpers and truly believe that they were worth the money I invested on them. I will % be buying more as I acquire more RugerMKIV22/45 Single Stack 10 round 22lr magazines! P.S. Installation is super easy and quick to do, just use a vice to hold your mags firmly, which will allow you to use both hands to remove and replace the stock mag bumper for TK s Tomahawk Hooked mag bumpers. Use a small flathead screwdriver to depress the mag spring w one hand, and while keeping the mag spring compressed, (so tension/ pressure is off the stock mag bumper) you can slide the stock mag bumper off (careful not to lose the mag spring) and use other hand to slide TK s Tomahawk Hooked Mag Bumpers ON!! It really is that easy . I only wish Tandemkross would offer a bigger Discount for those that wish to Buy Multiple 2-Packs at a time!!

    tonahawk bumper

    The bumper needs a little mold modification,there's a dimple that should be omitted where the spring guide first makes contact during installation.It's a pain to get the guide past it.Other than that it accents the appearance beautifully and a real help for big hands

    Great addition

    We installed these on the magazines for my daughters gun she uses for steel challenge. They make magazine changes and manipulation way better than stock. They are well made and worth the investment

    Tomahwwk hooked magazine bumpers for Ruger Mark IV

    Posted by Gerald on 29th Mar 2021

    These are not totally necessary but work really nice for my "pinkie" finger when I am shooting with 2 hands. I need to commend Tyler Marcos the customer service representative. I was having some difficulty installing the bumpers and he walked me through step by step to get them installed. I was a light construction equipment salesman for 40+ years before I retired. We worked very hard to get people like Tyler and to train them to give service like he does. If anyone has any problems with the items they get from Tandemkross they should call and ask for Tyler, not that their other service reps aren't probably good. It is just that my experience with Tyler and this company are very pleasing and it is refreshing to know there is still a "service oriented" company out there. Thanks again, Tyler and Tandemkross.
