Tandemkross
The Tandemkross Titan Extended Mag Release for Ruger Mark IV 22/45 addresses one of the most common complaints about this .22 pistol: a factory magazine release button that's cramped and difficult to operate, especially for shooters with smaller hands or younger competitors. Tandemkross solves this with a thoughtfully engineered upgrade that gives you two button options—a taller, wider checkered round button and a grooved paddle-style extension—so you can choose the ergonomic solution that works best for your hand size and shooting style. The paddle can even be angled up or down for a custom fit that feels natural to your grip.
Built from robust steel and anodized aluminum, the Titan is made to withstand years of regular shooting without wear. Both button designs feature deeply textured surfaces that grip your finger securely, eliminating the fumbling that slows down reloads. Installation is straightforward—if you can field-strip a Ruger Mark IV, you can swap in the Titan using the included instructions. The black finish integrates seamlessly with most Mark IV configurations, though the hardware is designed to pair well with any color of frame.
Whether you're introducing a younger shooter to the platform, competing in .22 rifle or pistol competitions that also use the Mark IV, or simply tired of adjusting your grip to reach the factory release, the Titan delivers the kind of practical ergonomic upgrade that makes every range session and hunting trip smoother. It's one of those small changes that remove friction from your routine and let you focus on shooting.
