I bought this HK model 502 shotgun. I don’t know much about it except what I heard from the LGS (rare, mainly delivered to police forces) and the little info I found on the internet

Is anyone familiar with this weapon ? There is also contradictory info whether it can shoot slugs

“Only buckshot can be fired due to the muzzle device that shapes the shot horizontally in an oval pattern”

“An unusual feature of the HK 512 shotgun was special shot diverter, mounted on the barrel of the gun. It was a sort of muzzle device, intended to create oval, rather than round shot patterns. Depending on the tactical situation on hand, this shot diverter could be set (rotated) for horizontal or vertical dispersion. It also allows use of most types of standard 12 gauge slugs.”
