I have one that I would sell.
At this time no,there are not any available.You could have a model 1300 slug barrel redone and have the gas ports added to this barrel.Then it will work fine in your model 1400 Winchester shotgun.
Not anymore but I hear you can take a 1300 barrel and have gas ports added and that should work.
As long as the slug barrel is smooth bored(does not have rifling) then it can be used with bird shot.
Yes, I don't think you should have a problem, but your pattern may not be consistent.

Rifled Slugs are meant for smooth bore barrels mainly. The rifled slug is made of lead and so if you shoot it through a rifled barrel the lead touching the rifling will cause some of the lead to peal off and can build up over a very short period of time. Also the facft that you are shooting a rifled slug through a rifled barrel would cause the bullet to become extremely unstable and inaccurate. Rifle barrel sare meant for sabot slugs (slugs with a plastic wad surrounding the outside). You should eb good though to shoot a rifled slug out of your barrel with a mod choke tube, but smooth bore deer barrels are ideal.M.I.
