ABSTRACT:
A compensator for a handgun comprises a barrel bushing having a first end inserted into the forward end of a slide and slidably receiving the barrel, and a second end projecting away from the barrel and slidably receiving a compensator weight having an external shape which conforms to and forms an extension of the slide. A bias spring mounted in the chamber beneath the barrel has a spring rod extending therethrough, the forward end of which projects into an opening in the lower end of the compensator weight. A projection on the barrel bushing retains a spring plug, slidably mounted on the spring rod, in a position to preload the spring and normaly urge the compensator weight toward the barrel. At least one threaded member provided in the compensator weight secures the compensator weight to the spring rod to prevent the compensator weight from experiencing either axial of rotational movement relative to the spring rod. The compensator weight adds significant weight to the forward end of the handgun, and well in front of the barrel to significantly reduce recoil resulting from the firing of the handgun. The compensator weight, appearance and shape permits the handgun to be placed within and easily withdrawn from a standard hip-mounted holster. The barrel bushing increases the drag between the barrel and slide, futher contributing to a reduction in the recoil action. The mounting of the compensator weight assembly upon the handgun is simple and straight-forward and requires no modification of the handgun components and further may be easily and readily disassembled from the handgun enabling the handgun to be returned to its normal configuration. The weight compensator may also be provided with exhaust ports for enabling blast gas to exit upwardly through the bushing and compensator weight, which further serves to reduce recoil.
