The Ruger MP9 is a 9mm submachine gun/machine pistol introduced by Sturm, Ruger in 1995. It was created by Uziel Gal in the early 1980s. It is similar to the Uzi, his most famous creation, using a telescoping bolt, but fires from a closed bolt. The gun also has a quickly detachable barrel that is spring-loaded to cushion the impact of the bolt on closure. The cocking handle is located at the top of the receiver. It also has a substantial integrated folding stock. It was made in very limited numbers. The MP9 submachine gun was designed as a compact weapon for law enforcement forces. In 1995, the MP9 was released for police and military sales in the United States. The gun features three positions safety/fire selector with "safe", "semi-auto" and "full-auto" positions, as well as a separate firing pin block to increase safety. The MP9 has sometimes been called an improved Uzi.
