DPM Glock 19/23/25/32/38 All Gen Magnetic Standoff/Glass Breaker. The DPM Mechanical Recoil Reduction System is not included in the package. The DPM Magnetomechanical Recoil System uses the Mechanical Recoil Reduction System and a separate ?agnetic base which mounts to the firearms forward tactical rail. This system works due to the contained multi springs within the rod in cooperation with the magnetic base which holds the slide in its battery position with increased resistance and momentarily delays rearward movement of the slide. This action will achieve the maximization of gases escaping from the barrels muzzle consequently causing the slide to move back more gently and transmit less kinetic energy to the shooter. The installation requires no modification to the weapon.
