# SIG Sauer MPX - Guns For Sale

The SIG Sauer MPX is a 9mm semi-automatic firearm available in pistol, carbine, and SBR configurations. It uses a short-stroke gas piston system for reliable cycling across conditions. Controls (safety selector, magazine release, and charging handle) are fully ambidextrous. The monolithic upper receiver includes a full-length M-LOK handguard and a Picatinny top rail. A quick-change barrel system allows length and configuration changes. The aluminum frame is lightweight, and folding or telescoping stock options are available depending on configuration.
