Slide Velocity

The slide velocity of a semi-automatic handgun is an important metric as it is relative to the recoil felt by the shooter and the feed reliability of the firearm. Slow motion video analysis of the tested Remington R1 1911 is presented below.

Muzzle Flash

When a small arm is fired, three target signatures emerge at the muzzle: noise, flash and smoke. Reducing the muzzle flash of a defensive firearm is important because it reduces the likelihood of an opponent visually determining your firing position. While this is most relevant to the world of rifles, a small muzzle flash from a handgun is also important as a means to minimize your “night blindness” after shooting and secondarily important as a means to conceal your firing position from attackers located at some distance from your location.
