Enhanced Micro Pistol with a 4-inch barrel in 9mm. The EMP was purpose-designed as a smaller 1911 — not a cut-down Government — with a dedicated compact frame, 9mm-optimized internals, and carry-contoured edges. The 4-inch Compact adds a longer barrel for improved ballistics and pointability over the 3-inch. Type: Pistol Action: Semi-Automatic Caliber: 9mm Capacity: 9 Year introduced: 2015, USA Weight: 28 oz Overall length: 7.5" Status: Active Intended use: Carry, Concealed Carry
