US12631411 - Pistol compensator components, systems, and methods

In a preferred embodiment, a pistol compensator system comprises a compensator, an elastomeric spacer, an assortment of variously sized shims, a spring guide rod, and a spring plug. The compensator of this system comprises a body, a barrel cavity, a threaded bore, an oval rod cavity, and a plug cavity. The spring plug of this system comprises a latch extension. The spring guide rod of this system comprises a muzzle end. When this preferred embodiment is installed on a pistol, if the pistol is in battery (slide closed) the latch extension is disposed in the plug cavity, and if the pistol is out of battery (slide back) the muzzle end of the guide rod is disposed in the rod cavity. In this preferred embodiment, the compensator is tensioned to the end of the barrel by the elastomeric spacer and a shim.
