Heckler and Koch have long dominated the marked for submachine guns with their MP5 models. This design is over three decades old, and H&K has been busy for over a decade with designing a new submachine gun. The UMP45 (Universal Machine Pistol caliber .45) is the final product of this development, and it looks to be as sure a winner as the MP5 series is.
The entire stock is made from a polymer, giving the gun high strenght, yet low weight. The Buttstock can be folded onto the right side of the gun as a standard, yet is very stable and solid feeling. On the stock are several Weaver-type rails, for mounting equipment on. Instead of the MP5`s roller-delayed action, the gun has a simple Blow-back action. It fires from a closed bolt. Several trigger options are available.
The most surprising item is the caliber: the UMP fires the .45 ACP cartridge, and not the 9mm as most other submachine guns. A variety of different accesoires is available, incluiding a sling, a vertical fore-grip, silencers, sights and lamps.
The UMP45 is delivered with a 25 round magazine standard, but 10 round magazines are also available.
