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.

These drop-in Ruger magazine bumpers attach to the bottom of the factory magazine without any glue or gunsmithing - installing in minutes!
