Overview

The SIG MODX-9 is SIG's modular titanium 9mm pistol and PCC suppressor and the factory-recommended can for the MPX line when running a SIG-built suppressor. The baffle 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, which is class-competitive with the HUXWRX Flow 9K Ti.

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 (the SLX line of rifle cans, MPX/MCX accessories, the Clutch-LOK ecosystem). 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 will feel more bolt-carrier blowback than they would with the Flow 9K Ti. Both cans land at the same $899 street price; the choice comes down to flow-through vs modular configurability and SIG ecosystem integration.

NFA item, requires ATF Form 4 and a $200 tax stamp. Most national NFA retailers price the MODX-9 between $899 and $1,044 depending on market and configuration.
