Patent ID: 8087338

Claim:
A suppressor device operatively configured to be attached to a firearm configured for shooting a projectile, the suppressor device comprising: a) a suppressor body defining a first primary expansion chamber and a second primary expansion chamber where the second primary expansion chamber is positioned longitudinally forward of the first primary expansion chamber, the first and second primary expansion chambers having a projectile passage positioned therebetween, b) a surface defining a passageway from the first primary expansion chamber to a slip chamber where the slip chamber provides communication to the longitudinally forwardly positioned second primary expansion chamber for expelling gas therein, the slip chamber in communication with an advance port in communication with the second primary expansion chamber, c) whereas the slip chamber provides for communication between the first and second primary expansion chambers to allow compressed gas to flow from the first expansion chamber to the second expansion chamber to preload the second expansion chamber with compressed gas prior to the entry of the projectile therein, where the second primary expansion chamber comprises a port providing communication to a capacitance chamber, and where the capacitance chamber is positioned at a substantially radially opposite location to the slip chamber.
