The worst HK?
This review critically examines the Heckler & Koch UMP, contrasting it unfavorably with the iconic MP5.

Furthermore, the UMP's simple straight blowback action is deemed a mechanical regression compared to the MP5's roller-delayed system. A live-fire demonstration showcases the 9mm UMP's handling and recoil.
