SMG - .45 ACP - Germany - 800 RPM - Another part of "Project 50" was the creation of a SMG family to replace the MP5; the UMP45 is the first product of this new line.  While it weighs less than the MP5K-PDW, the low bore line of the UMP45 allows it to be as controlable as the full-sized MP5. D.E. Watters
