SIG MODX-9

The SIG MODX-9 is SIG's modular 9mm pistol and PCC suppressor and a natural factory-family option for the MPX line when running a SIG-built suppressor. The stack is fully modular, configurable between a full 7.5-inch quietest configuration and shorter setups for shooters who prioritize handiness over absolute sound reduction. Total weight in the full configuration is 8 oz.

The MODX-9 features 21 points of impact adjustment, so a precision-minded MPX owner can dial the can to match the host's zero rather than accept whatever POI shift a fixed direct-thread can produces. The kit ships with a fixed barrel spacer for carbine and fixed-barrel use (the right config for the MPX) plus a Nielsen-style booster setup for tilting-barrel handguns. Compatible mount options include direct thread and SIG's Clutch-LOK QD when paired with the Clutch-LOK adapter.

The MODX-9 is the right pick for shooters who want a SIG-branded factory can that integrates cleanly with other SIG products. Compared to the HUXWRX Flow 9K Ti, the MODX-9 is a traditional baffle suppressor without flow-through technology, so MPX shooters running the MODX-9 should expect more back pressure than they would with the Flow 9K Ti. The choice comes down to flow-through versus modular configurability and SIG ecosystem integration.

The MODX-9 is a premium SIG pistol/PCC can with official MSRP around $949.99 and market pricing that can vary by configuration.
