The Tandemkross Ruger Mark IV extended magazine release gives you a faster, more ergonomic way to drop magazines on your rimfire pistol. Instead of hunting for a tiny factory button, you get two interchangeable button styles—a checkered round button and a grooved paddle—so you can choose what works best for your hand size and shooting style. Both are substantially larger than the stock release, making mag changes smoother whether you're running competition drills, training juniors, or just prefer a more accessible control layout.
The paddle-style button angles back toward your thumb, making it especially friendly for shooters with shorter thumbs or smaller hands who'd otherwise need to shift their grip. The round button sits taller and wider but stays low enough that larger hands won't bump it accidentally. You can even adjust the paddle's angle to dial in the exact position that feels natural to you. Installation is straightforward—if you can field-strip your Mark IV, you can swap this in without gunsmith work.
Built from robust steel and anodized aluminum with deeply textured surfaces, the Titan extended magazine release is built to last through years of range time and competition. The black finish complements most Mark IV setups and pairs well with the pistol's factory lines. This upgrade works on the Mark III, Mark IV, Mark IV Target, Mark IV Hunter, and Mark IV Competition.
