UMP

"A submachine gun of modern design that features excellent accuracy. Its lower firerate is offset by the high stopping power of the .45 caliber round it uses."

- The Arsenal

The HK UMP (Heckler & Koch Universal Machine Pistol) is a Sub Machine Gun.

Overview
The UMP has a significantly lower rate of fire than other Submachine Guns, but in turn has a far higher damage count per round. This high damage can kill in approximately 3 shots at an optimal range of 20 meters. The high damage and moderate accuracy of the UMP has seen it become a favorite weapon of players. However, its recoil increased twofold in the 10-16-08 Patch and has therefore seen a decrease in the popularity among users.

Trivia

 * This weapon was once offered as a default weapon change. As of the 2-3-10 Patch, Default Weapon Changes have been removed from the Black Market and are no longer available whilst every other weapon in the Black Market were offered for Permanent Duration.
 * The UMP LE, statistically equivalent, was offered during the 2012 Christmas Sale for permanent, for a price of 70,000 GP. It isn't forgeable into a Thompson. This is most likely because the Thompson was on sale for permanent duration via NX purchase during this sale.
