The Nemo Omen Mongoose pistol in 9mm (brand part no. MNG-9MM-CTB) is a lightweight, low-recoil pistol-caliber carbine pistol built around a 5.8-inch threaded barrel and a brace in place of a shoulder stock. Nemo runs the Mongoose on a short-recoil operating system rather than straight blowback, and the PCC-specific frame keeps the whole package at just 3.6 pounds. An ambidextrous safety runs the controls, and the compact 13.67-inch overall length makes the Mongoose well-suited to competition, home defense, and plinking alike. Among AR pistols and pistol-caliber-carbine platforms, this Mongoose configuration favors shooters who want a genuinely light, soft-shooting 9mm pistol.
