Boberg XR-9 Shorty.

Action: Rotating-Barrel Locked-Breech. Safeties: 3. XR9 is a pocket pistol with a full length barrel, having the magazine located directly under the chamber. The patent-pending feed mechanism grabs a cartridge from the magazine and delivers it straight into the chamber. This allows the chamber clearance to be significantly less, causing less energy and noise to blast out the back. With this combination, kinetic energy is maximized, and in many cases will exceed the energy produced in full-sized pistols. XR9 features a pull-back style mechanism. These type of mechanisms had been successfully used in past weapons, but only in machine guns, of which were designed by Hiram Maxim, John M. Browning and others. The famous Browning 1919 machine gun was a very reliable weapon of war. The Boberg XR9 differs from prior technology in that the cartridge is positively controlled from the time it is extracted from the magazine until the empty case is ejected from the breech area. After extensive durability testing the new improved, more advanced version of Boberg XR-9 will hit the market in second part of 2009.
