You are in luck. FN Hersal has released a new pump shotgun, made in America and built on the Winchester 1300 action, that comes with an 18 inch barrel, rifle sights, drilled and tapped receiver, synthetic stock, parkerized finish, 8 shot capacity, and three interchangeable choke tubes, for only about $50 more than the Plain Jane Win. 1300. This would be a GREAT hog gun.
The name the company is actually FN Herstal America, which I understand to be a subsidiary of FN Belgium. It has a license from Wincheser to use the 1300 action.
They also make a $600 super police version of this gun, with a folding stock (like the M4 variant of the AR 15) and luminescent sights. But, I don't think you need to go this far for the hogs!
