Note: DryFireMag is not compatible with firing pin-activated laser cartridges. The DryFireMag for Ruger RXM pistols lets you train smarter by eliminating the need to rack the slide between trigger presses. This means you can build real muscle memory while keeping both hands on your pistol and your sights on target-exactly how you&';d respond in a real-life situation. Designed for the Ruger RXM, this DryFireMag simulates a factory 5-5.5 lb trigger pull, giving you realistic feedback with every press. Want a different feel? Upgrade with our optional spring kit to adjust your trigger weight to your preference. The base plate on the Ruger DryFireMag is RED for easy identification, so there&&';;s never any confusion with live mags during your practice sessions. Whether you&';re warming up at the range or honing your skills at home, the DryFireMag makes dry fire training effective, safe, and seamless. If you&&';;re using a custom trigger that resets to the forward "cocked" position, we recommend removing the DryFireMag spring for a smoother, more natural press.
