Ruger MP9

The Ruger MP9 is a 9mm submachine gun/machine pistol introduced by Sturm, Ruger in 1995.

History and Design
It was created by Uziel Gal in the early 1980s. It is similar to the Uzi, his most famous creation, and has sometimes been called an "improved Uzi". 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 Ruger MP9 was made in very limited numbers.

Operation
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 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. The gun uses a telescoping bolt, but fires from a closed bolt. It also has a substantial integrated folding stock.
