I have been looking for a shotgun for awhile now and the different choices are starting to all blur together. I thought I could tell you what I want and maybe you have an idea I have not looked at yet. Ideally: 12 g. w/3.5" ability semi auto (if I can afford it) either a "combo" set up or have aftermarket/factory barrels...want duck barrel, short defense barrel, and rifled slug barrel w/cantilever for scope. have mag tube extensions available. A pump action with the above would be second pick. A gun like the Winchester SXP camp/field combo looks good...but lacks a rifled cantilever barrel. My experience with Win guns is getting extra barrels is pretty tough...I don't know if they have a rifled barrel available. Also I would like tube extensions for it when placed in the defense role, not sure if they are available. The Mossberg 835 ulti-mag combo looks good, but lacks the "defense" barrel. So, can anyone help? One gun, 3 barrels available ? If I could find barrels to fit my 1300 defender...a duck and a scoped rifled kind I'd be set, but I don't think they make them all...and the price would be about that of a new gun anyway.
