I would like to know if there any companies that full rifled slug guns?I contacted a few Italian companies that make O/U with one barrel rifled and the other smooth.When I talk to them say that would make the other barrel rifled also but they wouldn't regulate it..So this the reason I posted here to see if buying
This slug gun with unregulated ? If anyone would they post..My first choice would be a SXS but they won't do one just in the o/u..

Check out Galazan's website - their RBL professional model is a fully rifles 20 gauge SxS that is regulated and has provisions to mount a scope.

Connecticut Shotgun Manufacturing Company built a very nices SXs fully rifled 20 gauge called the RBL they are in the 7K range. Aaron Little who post on here has a well earned reputation. He could deliver you such a a gun in any gauge you wanted.

I have one in 12ga built by Lou Allesandri for the movie Jurassic Park as a 600 NE wanna-be, but lighter for the actors to carry. It came with cool loading tools and brass cases. I had Griffin & Howe go over it, tighten up the action and re-do the triggers, but I'm sure it's way more than you need.
