On March 2, 2017, SIG filed a patent with the United States Patent and Trademark Office for an “Integral Eccentric Firearm Silencer.” That patent was approved on July 24, 2018.
The patent describes the Integral Eccentric Firearm Silencer thusly:
An eccentric firearm silencer includes an an elongate body having a projectile entry end, a projectile exit end opposite the projectile entry end, a bore extending through the projectile entry end and the projectile exit end for conducting a projectile therethrough, and a longitudinal axis passing through the bore.
The elongate body is configured to be coupled, rotatably about or slidably parallel to the longitudinal axis X, to a barrel of the firearm at or near the projectile entry end.
The elongate body includes a propellant gas expansion chamber disposed adjacent to, and in fluid communication with, the bore for receiving a propellant gas
Also, the elongate body includes a capsule container mounted eccentrically adjacent to, and in fluid communication with, the propellant gas expansion chamber.
The capsule container is configured to receive therein a capsule or ablative cartridge containing an amorphous solid or a liquid.
The Scoop on SIG’s Integral Eccentric Firearm Silencer
Essentially, this looks to be a wet suppressor that uses an ablative, rather than baffles, for sound reduction. Based on the drawings included with the patent, we’d hazard a guess that this suppressor will be paired with the Sig Sauer P320. We will keep you informed of any updates regarding the silencer.
