The newest pistol suppressor line from SIG SAUER features completely modular and configurable titanium baffles for the ultimate light-weight performance that allows the user to personalize their suppressor for overall length weight and sound. The MOD-X9 provides 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.
