Introduction

The UMP is a modern sub machine gun of German origin. The UMP was developed by Heckler & Koch in the 1990's and supplements the famous MP5 in their lineup. Although the MP5 is considered very reliable and highly accurate it is also rather heavy, very costly and it is difficult to mount accessories, although many are available. The UMP is lighter, less costly, more modular and available in various calibers. The name UMP stands for Universale Machinenpistole, which is German for Universal Machine Pistol.

Design

Together with the G36 the UMP is H&K's departure from the famous roller locked delayed blowback mechanism. The UMP is blowback operated and available in three calibers and can be converted by replacing bolt, barrel and magazine. Except from the internal mechanism and barrel the UMP is fully made out of high strength polymer, resulting in a low weight weapon. The controls are fully ambidextrous and various trigger groups are available. Picatinny rails allow a wide variety of optics and accessories to be fitted.

Firepower

The UMP is available in 9x19mm NATO, .40 S&W and .45 APC. In 9mm and .40 it uses 30 round magazines, while the .45 magazines hold 25 rounds. The rate of fire varies per caliber and is roughly 700 rpm in 9mm and in .45 it is 600 rpm. The limited rate of fire makes the UMP controllable, even when firing the more powerful types of ammunition. The effective range is quoted to be about 100 meters.

Users

The UMP is used by police and counter terrorist units world wide and also is in limited military use. The UMP is often used alongside the MP5 it supplements. All three calibers are in common use, although the heavier calibers are more common in the USA and the UMP9 is more common in Europe.

Variants

UMP

The UMP45 is the original model of the UMP family. It fires the .45 ACP round from straight 25 round magazines. The UMP40 is a derivative of the UMP45 that fires the .40 S&W round from straight 30 round magazines. The UMP9 is the latest model of the UMP family. It fires the 9x19mm round from 30 round curved magazines and is mainly intended for sales outside the USA.

USC

The USC is a civilian carbine that is based on the UMP45. It has a much longer barrel, accepts only 10 round magazines and fires semi-automatic only.

At first the USC was produced in white polymer but this has switched to dark grey.
