MPX-SD

The MPX SD from Ronin Arms transforms the SIG MPX into a fully integrally suppressed system, delivering exceptional performance with standard 9mm ammo. Featuring a 5.75″ ported barrel mated to a 12″ Defcon4 SD suppressor, this build offers whisper-quiet operation, reduced recoil, and consistent subsonic cycling—no specialty rounds required.

Expertly machined and hand-tuned under the “One Gun, One Gunsmith” standard, the MPX SD delivers smooth function, precise accuracy, and tactical-ready control. For compact performance, explore the Ronin Edition MPXSD-K or customize your own via the MPX SD Conversion service.
