Pistol compensator components, systems, and methods

A method of attaching a compensator to a threaded pistol barrel comprising the steps of:

• (a) acquiring a compensator comprising internal threads, a rod cavity having a vertical oval configuration, a pistol barrel comprising external threads, an elastomeric spacer, and an assortment of variously sized shims;
• (b) selecting the thickest of the variously sized shims;
• (c) engaging the compensator threads onto the barrel threads with the elastomeric spacer and the selected shim between the compensator and the barrel;
• (d) rotating the compensator about the barrel until the compensator is tight;
• (e) determining if the tightened compensator is oriented correctly on the barrel;
• (f) if the tightened compensator is incorrectly oriented on the barrel, selecting the next thickest of the variously sized shims;
• and
• (g) repeating steps (c), (d), (e), and (f) until the tightened compensator is oriented correctly on the barrel.

A pistol compensator system configured for deployment on a pistol that comprises a barrel having (i) a barrel tube with an unthreaded end terminating at a muzzle face and (ii) a threaded muzzle extension extending from the muzzle face and having a first diameter, the pistol compensator system comprising:

• a spring guide rod comprising a muzzle end;
• a spring plug comprising a latch extension;
• a compensator comprising a body configured with
• a barrel cavity sized to accept at least a portion of the unthreaded end of the barrel tube and having a second diameter,
• a threaded bore sized to accept the threaded muzzle extension,
• a rod cavity having a vertical oval configuration, and
• a plug cavity formed in an upper rear portion of the rod cavity and sized to accept the latch extension;
• an elastomeric spacer having an outer diameter greater than the second diameter and an inner diameter smaller than the first diameter;
• and
• a shim;
• the system having an assembled configuration on the pistol in which
• at least a portion of the unthreaded end of the barrel tube is disposed in the barrel cavity,
• at least a portion of the threaded muzzle extension is disposed in the threaded bore,
• the shim is disposed around the threaded muzzle extension with one side of shim disposed adjacent to the muzzle face and a second side of the shim disposed adjacent to the elastomeric spacer,
• the elastomeric spacer is disposed around the threaded muzzle extension with one side of the elastomeric spacer adjacent to an inside face of the barrel cavity and a second side of the elastomeric spacer adjacent to the shim,
• the elastomer space is compressed vertically between the barrel cavity and the threaded muzzle extension and horizontally between the barrel cavity and the shim, and
• the latch extension is disposed in the plug cavity when the pistol is in battery, and the muzzle end of the spring guide rod is disposed in the rod cavity when the pistol is out of battery.
