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 weapon that offers the advantages of a simple 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. 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.
