1999 and it is still produced. This SMG is in service with some law enforcement agencies worldwide.
The HK UMP is a blowback-operated, selective fire weapon, fired from the closed bolt. It’s first versions, the UMP-45 and UMP-40 were chambered for .45 ACP and .40 SW ammunition respectively. Later a 9 x
19 mm version became available (UMP-9). All versions have similar design, apart from the different chambering.
The UMP can fire in semi-auto, full-auto, 2- or 3-round burst modes. It’s fire mode selector is also acts as a safety lock. This fire mode selector is fully ambidextrous. Cocking handle is located at the front of the receiver.
The HK UMP is available with 25- and 30-round capacity magazines. The UMP-45 is typically fed from 25-rouns magazines. Other versions are fed from the 30-round one. The .45 ACP and .40 SW versions use straight magazines and the 9-mm comes with curved magazines.
