Abstract
Slide decelerator for a firearm has a cylindrical cavity formed in the metallic receiver of the firearm and a deformable mass of elastomeric material is disposed within the cavity. A piston is slidably fitted into the cavity and a rod extends outwardly from the piston for engagement with a depending portion of the slide. The elastomer consists of a cylindrical plug which has a diameter substantially smaller than the inner diameter of the cavity and an axial length approximately equal to that to the length of the cavity. Upon firing, the slide, being moved rearwardly by blow-back of combustion gases, will impact against the rod and elastomeric material will be deformed to thereby absorb the kinetic energy of the slide. As a result, the slide is stopped before impacting against the receiver of the firearm.
