The Iver Johnson HP18-12 is a 12 Gauge Semi-Automatic shotgun with an 18.5" smooth bore barrel. This shotgun accepts 2-3/4" & 3" shells. The stock is two-piece detachable; meaning it comes with a full stock pistol grip, but with the push of a button, the stock detaches and leaves the pistol grip on the shotgun, giving you two types of stock in one. Features an externally threaded muzzle brake to help reduce felt recoil.
The Iver Johnson is wicked mean. It is monster you need to tame. I was not expecting it to beat me but you know what they say about pleasure and pain. I do have a couple of complaints, like the take down pin walking out and the annoying way you need to remove the charging handle to clean the gun, but I still recommend this nonetheless. This is a home defense weapon, and I would hate to be on the receiving end of the Iver Johnson HP18 12 Gauge Semi-Automatic Shotgun!
