A truly modern submachine gun, the UMP is made using the latest in advanced polymers and high-tech materials. The UMP is a cost-effective, state-of-the-art platform that offers the advantages of a simple blowback operating system, lightweight, low cost, uncompromising reliability, and modularity.

Like all HK submachine guns, UMPs fires from the closed bolt position for accuracy and safe handling. 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.
