The SIG SAUER MODX-9 is a modular 9mm suppressor that lets you build the can your host actually needs — run it full-length for maximum sound reduction or shortened for a compact, holster-friendly setup. This MPX configuration threads M13.5x1 LH, mating directly to SIG's MPX platform, where the pistol-caliber carbine's already-soft shooting becomes downright pleasant behind a suppressor. SIG's suppressor line benefits from the same engineering muscle behind its military contracts. As an NFA item, the MODX-9 requires ATF approval and transfer through a licensed dealer — modularity worth the paperwork.

This firearm ships to your chosen FFL dealer for transfer. Order online from Dawson Defense, an Arizona-owned licensed dealer and importer.
