Unconventional design. Unmatched performance. The SIG MPX™ redefines the submachine gun category with a new level of operator safety, in-field adaptability and proven reliability in the harshest environments. There’s nothing else like it. And it’s only available from SIG.
Every aspect of the SIG MPX firing system has been rigorously designed and tested. So in the heat of the moment, you can respond confidently and effectively, even under adverse conditions.
This is the semi-auto pistol version of the MPX submachine gun, with a factory folding SBX Pistol Stabilizing Brace.
