UMP45

The UMP (Universale Maschinenpistole, German for "Universal Submachine Gun") is a submachine gun developed and manufactured by Heckler & Koch. The UMP is a blowback-operated select-fire submachine gun firing from a closed bolt. It features a polymer stock that is able to be folded for compactness, a paddle-style magazine release, and a handguard that is able to accept accessories, such as vertical foregrips. The barrel is approximately 8 inches long, and there may be rails on top of the receiver to mount optics. As originally designed, the UMP is chambered for larger cartridges (.45 ACP and .40 S&W) than other submachine guns like the MP5, to provide more stopping power against unarmored targets (with slightly lower effectiveness at longer range) than the MP5 (largely offered in 9×19mm, albeit with short-lived production of 10mm Auto and .40 S&W variants). A larger cartridge produces more recoil, and makes control more difficult in fully automatic firing. To mitigate this, the cyclic rate of fire was reduced to 600 rounds/min, which makes it one of the slower firing submachine guns on the market.
