Note: This is the Smart DryFireMag ONLY. This Smart DryFireMagA(R) requires the Smart Optic Laser (Red or IR) to function as intended. This Smart DryFireMag can be purchased to add to an existing Smart DryFireMag Training System. The Smart DryFireMagA(R) is only compatible with the Smart SureStrike(TM) Optic Laser Cartridge by Laser Ammo USA Inc. and is not compatible with any other laser cartridge. Some Smart DryFireMag models are non-weighted magazines. Unlock a new level of dry fire training with the Smart DryFireMag for GlockA(R) 10mm/45 Auto pistols. This innovative training tool combines realistic trigger-reset dry fire with Red or Infrared (Invisible) laser (sold separately-required) feedback, all without needing to rack the slide between shots. That means smooth, consistent reps that help you build real-world skills and solid muscle memory. This model simulates a factory Glock 5.5-6 lb trigger pull for realistic, responsive training. Want a custom feel? Add the optional spring kit to adjust your trigger weight to your liking. The blaze orange base plate provides clear visual identification, helping you stay safe and organized during practice sessions. Whether you&';re sharpening fundamentals or troubleshooting your live fire mechanics, the Smart DryFireMagA(R) makes training simple, seamless, and more effective. If you&';re running the Glock Performance Trigger or another custom setup that resets forward to the "cocked" position, we recommend removing the internal spring for a more natural trigger press experience.
