The thUMPer is a revolutionary can designed expressly for the H&K UMP .45 caliber subgun. It's short overall length and solid construction make it tough enough and maneuverable enough for the most demanding environments while not interfering with the UMP's blowback action.

The thUMPer's light weight also keeps the overall weight of the weapons system low to avoid negating the advantages of the UMP's polymer frame. The thUMPer is manufactured of the finest materials for truly world class performance and toughness for the most demanding situations.
