Product Description

The newest pistol suppressor line from SIG SAUER features completely modular and configurable titanium baffles for the ultimate, lightweight performance that allows the user to personalize their suppressor for overall length, weight, and sound. The MOD-X9 and MOD-X45 provide class-leading sound performance and can be easily disassembled and reconfigured with fewer baffles when your priority is size over sound. The MOD-X suppressors feature 21 points of impact adjustment and come with a fixed barrel spacer for carbine use. Each MOD-X suppressor includes the most popular Imperial and Metric piston for its given caliber.
