Suppressor for a firearm

Abstract

The present invention describes a suppressor or silencer device for a pistol that does not interfere with a traditional pistol sight, yet is still able to suppress or silence the pistol in substantially equal to or greater efficacy than a traditional suppressor. This is accomplished by attaching an additional chamber on the bottom side of the tubular body (or “bore”) of the suppressor where the bullet is traveling; heated gas behind the bullet travels down into the chamber where its geometry slows the gas down before exiting the chamber.

What is claimed is: 
     
         1 . A suppressor for a firearm comprising:
 a. a tubular housing of cylindrical cross section having an interior cavity comprising a front end and a back end wherein the back end is attached to the end of a barrel of a firearm;   b. a supplemental housing having a front end with an opening and back end that extends longitudinally along the exterior surface of said tubular housing with an opening at the front end; and   c. at least one aperture in the shared surface between the supplemental housing and the tubular housing.   
     
     
         2 . The suppressor of  claim 1  wherein the interior cavity of the supplemental housing comprises a plurality of structures. 
     
     
         3 . The suppressor of  claim 1  wherein the supplemental housing is attached to the bottom surface of the tubular housing. 
     
     
         4 . The suppressor of  claim 1  wherein the supplemental housing is attached to a side surface of the tubular housing. 
     
     
         5 . The suppressor of  claim 1  wherein the tubular housing further comprises a plurality of baffles with a hollow tubular body of cylindrical cross section having sides that define a gas inlet and a gas outlet end, an interior and exterior surface, and are nested within each other in the interior cavity of the tubular housing. 
     
     
         6 . The suppressor of  claim 5  wherein the aperture in the shared surface between the chamber and the tubular housing is located between the back end of the tubular housing and the first baffle. 
     
     
         7 . The suppressor of  claim 5  wherein a plurality of apertures are located between the baffles along the shared surface between the supplemental housing and the tubular housing. 
     
     
         8 . A method for slowing the movement of propulsion gas behind a projectile traveling down the bore of a suppressor, comprising the steps of:
 a. removing gas from the original chamber containing the projectile;   b. channeling the removed gas through an auxiliary (or second) chamber having a geometric structure for suppressing noise; and   c. allowing the gas to exit out of the opposite end of the auxiliary chamber.   
     
     
         9 . The suppressor of  claim 8  wherein the structures within the auxiliary chamber comprise a plurality of walls arranged to force the gas to turn in different directions before exiting the auxiliary chamber.
