SIG SAUER Suppressors: Surpassing All Expectations
By Todd Burgreen
SIG SAUER has become a true “one-stop shop” for military, law enforcement and civilian operators. The SIG SAUER Silencer Division was formally created in 2014 with its major introduction to the shooting public taking place at the 2015 SHOT Show. SIG SAUER had earlier entered the suppressor market, but decided a formal distinct division headed by industry veterans Kevin Brittingham, founder of AAC, and Ethan Lessard would be the better path. Suppressor use has never been as popular for military, law enforcement and civilians. The benefits of suppressor use are hard to argue against.
This article will convey SIG’s commitment to improving suppressors across the board in terms of sound reduction, muzzle flash, durability, accuracy, mounting method, accuracy etc. While sounding ambitious, this will be accomplished by highlighting multiple models such as the SRD22, SRD556-QD, SRD762-QD and SRD45. SIG SAUER did not seek to mimic other suppressor designs; instead they chose their own path backed by engineering, experience and science.
Each type of SIG SAUER suppressor, albeit rimfire, pistol, rifle, has unique characteristics distinguishing it from competitor cans. The SIG SAUER SRD22 22LR Silencer features an aluminum outer tube with stainless steel baffles. The SRD22 measures 6.2 inches long, 1.25 inches in diameter and weighs 7.7 ounces. SIG SAUER lists sound signature reduction down to 117 decibels (db) with the SRD22. For reference sake, the actions of many semiautomatic .22 caliber weapons produce 125-130 decibels when cycling out and into battery. An unsuppressed .22LR produces approximately 142 decibels when fired. Unsuppressed centerfire rifles and handguns produce approximately 165 decibels. The SRD22 comes with both ½”x 28 tpi and M9 x.75 adaptors to facilitate mounting to typical US and European thread patterns found on 22LR weapons.
The SRD22 suppressor is easily disassembled for cleaning. This is especially important with a 22LR suppressor versus other calibers due to the preponderance use of lead in 22LR ammunition. SIG SAUER provides a tool that matches the end cap notches of the SRD22 facilitating easy removal. After removing the end cap the stacked stainless steel baffles are...
