The Ruger® MKIV™  22/45™  has become a favorite rimfire pistol among competitive shooters, like the Ruger® MKIII 22/45™  and Ruger® MKII 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 Magazine Bumpers for Ruger® Mark IV™  22/45™ , Ruger® MKIII™  22/45™  and Ruger® MKII™  22/45™  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.
