To mitigate this, the cyclic rate of fire was reduced to 650 rounds/min (600 rounds/min for the UMP45), which makes it one of the slower firing submachine guns on the market. A larger cartridge produces more recoil, and makes control more difficult in fully automatic firing. As originally designed, the UMP is chambered for larger cartridges than other submachine guns like the MP5 to provide more stopping power (with slightly lower effectiveness at longer range) than the 9x19mm MP5 provides. The UMP is a blowback operated, magazine-fed submachine gun firing from a closed bolt. Heckler & Koch developed the UMP as a successor to the MP5, though both remain in production. The UMP has been adopted by various agencies such as the U.S. The UMP (Universale Maschinenpistole, German for "Universal Machine Pistol") is a submachine gun developed and manufactured by Heckler & Koch.
