The UMP was designed in the 1990s by Heckler & Koch (HK), as a cheaper, lighter alternative to the MP5, [5] which made heavy use of polymers. [6] The UMP first entered production in 2000. [ 2 ] It was designed primarily for use by American military and law enforcement units, [ 7 ] as the MP5 was not available in .45 ACP, a round which was ...

Using a similar recoil reduction system, the H&K Mk 23 pistol fired more than 30,000 high pressure (+P) cartridges and 6,000 proof loads without damage or excessive wear to any major components. Abuse and function-testing of USPs have seen more than 20,000 rounds of .40 S&W fired without a component failure.

Four different barrel lengths from 230 mm (9.1 in) to 480 mm (19 in) and four stock models (short fixed, long fixed and two adjustable) will be offered.
Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves. In modern systems, the conversion is performed with semiconductor switching devices such as diodes, thyristors, and power transistors such as the power MOSFET and IGBT ...
