The Flux Defense MP17 adds a retractable stock, a Picatinny rail, and a second magazine that doubles as a forward grip to the Sig Sauer P320 pistol the Army adopted as the M17/M18 under the service's Modular Handgun System program. “Shoots like a carbine, holsters like a pistol.” That's the pitch behind the new Flux Defense system designed to transform the Army's brand new sidearm into a personal defense weapon.
