The Sig Sauer Silencer MDX-45 SS is a modular suppressor purpose-built for .45 Auto pistols and carbines that gives you real control over how your rig performs. Instead of being locked into one fixed length and sound signature, this suppressor lets you add or remove titanium baffles to dial in your priorities—whether that's maximum sound reduction at the range or compact size for carry and truck guns. The fully modular design means you're not stuck with a one-size-fits-all compromise.
Built from 3D-printed titanium baffles and stainless steel construction, the MDX-45 delivers the durability you need for serious shooting without unnecessary weight. The direct-thread design keeps things simple, and Sig includes both a .578x28 and M16x1 LH piston in the box, so you can mount it on most common .45 platforms right out of the box. The modular baffle system gives you up to 21 impact adjustment points, letting you fine-tune fit and performance to your specific host gun.
This is a suppressor for shooters who understand that one gun rarely does everything the same way. Whether you're running it on a defensive pistol, a range toy, or an AR-pistol in .45, the ability to reconfigure baffles means the MDX-45 adapts to your mission instead of forcing you to adapt to it.
