HDM 980


Compared to traditional shotguns, HDM bullpup shotguns offer noticeably more compact size while sporting barrels of respectable lengths. This makes those guns easier to maneuver in confined spaces, although specifics of bullpup ergonomics often require users to adjust their training and gun handling practices.

The first one is of HDM, a 12-gauge gas operated full metal semi-automatic, with a box magazine feed system. This one appears to be a more or less conventional semi-automatic shotgun concealed inside a clam-shell polymer housing. As such, this gun features only right-side ejection and has a cross-bolt type manual safety located way back on the stock behind the magazine housing. It can use 2, 5 or 10-round box magazines compatible with other HDM box-fed shotguns of the same caliber.
