Product Description The Volquartsen Extended Magazine Release for Ruger Mark IV 22/45-style pistols is designed to allow the magazine to sit higher in the frame to improve feeding reliability by helping prevent the bolt from sliding over the top round. Finished in black nitride and featuring a knurled surface for enhanced feel and control, this USA-made upgrade is built for performance-focused shooters. It will work with factory magazines; however, because the magazine is raised, Volquartsen highly recommends using this release with Volquartsen magazine base pads. When used with factory magazines and basepads, the magazine may sit slightly past flush at the bottom of the frame.
