UMP45

A truly modern submachine gun, the UMP is made using the latest in advanced polymers and high-tech materials. Available in three calibers (.45 ACP, .40 S&W, and by special order 9 mm), the UMP is a cost-effective, state-of-the-art weapon that offers the advantages of a simple operating system, lightweight, low cost, uncompromising reliability, modularity, and the capability to powerful cartridges like .45 ACP and 40 S&W).

Like all HK submachine guns, UMPs fires from the closed bolt position for accuracy and safe handling. Available in a variety of select-fire submachine gun configurations or as a semi-automatic only carbine, the HK UMP (Universal Machine Pistol) was designed with American law enforcement and military units in mind, as it includes a bolt catch feature to hold the bolt rearward when last round is fired.

The UMP can also be converted from between its three calibers (.45 ACP, .40 S&W, and 9 mm) simply by exchanging barrel, bolt, and magazine assemblies.
