ABSOLUTE CUSTOMIZATION
Sig Sauer's MODX-45 is the latest addition to Sig Sauer's pistol silencer line. The length is customizable, allowing the shooter to find the perfect level of suppression versus size. Even in the full length configuration, the MODX-45 is extremely light due to it's titanium construction. For even further customization, the piston features 21 different points of impact adjustment. This allows for fine tuning of the pistol and silencer combination.
The MODX-45 also ships with extra accessories not included with most competing products. It includes both .578 and M16LH pistons, as well as a fixed barrel spacer. With those three accessories, it can be used on nearly any 45acp firearm out of the box.
CAPITOL ARMORY'S OPINION
The MODX-45 excels at adapting to the shooters unique needs. It's not just a choice between a full length or K can anymore. Each baffle can be removed, allowing for fine tuning for dB versus length. Longer is more quiet, but shorter may fit better in a bedside safe. In addition to being adjustable for any length, it also is extremely light. The titanium construction keeps durability high without the additional weight. The box also comes with an additional piston and fixed barrel spacer, which most of the competition sells as additional accessories.
