[TFA] H&K UMP45

The UMP45 (Universale Maschinenpistole, German for "Universal Submachine Gun") is a submachine gun developed and manufactured by Heckler & Koch. The UMP45 has been adopted by various agencies such as the U.S. Customs and Border Protection. Heckler & Koch developed the UMP45 as a lighter and cheaper successor to the MP5, though both remain in production. As originally designed, the UMP45 is chambered for larger cartridges (.45 ACP) 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. 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. The UMP45 is a blowback-operated select-fire submachine gun, being fired from the closed bolt. The receiver is made from the polymer, the controls are fully ambidextrous. It can be fired in full-auto, in single shots, and in 2 round bursts. UMP45 also has bolt hold-open device, which traps the bolt in the open position when the last round from magazine had been fired.
