The MP 18,I, the first submachine gun in WWI, weighs 9.3 lbs and is 32 inches long. It utilizes a 32-round Luger Trommel magazine, which causes a left-side weight bias. Operating from an open bolt, it features a single-stage, fully automatic trigger. While recoil is minimal with 9mm, the heavy bolt mass impacts precision, and its sights are designed for short-range suppressive fire.
