I have many slug guns. For the money I would go with a Mossberg 500 combo, it comes with a rifled barrel thats ported, and cantilever mount so you can put a scope on it, it has NO iron sights, also it comes with either a 26" or 28" vent rib with a few chokes!!! I would say that today it sells for just under $400, I paid if can remember about $325 years ago. This gun is very good, and a great value. You may also look into the Remington 870 line, they have many different set ups for this model. Whatever shotgun you get, you have to try different slugs, but with that said I find that the Lightfield EXP slugs work perfect with every slug gun I have thats rifled including my few Mossbergs, Ithaca and Remingtons. Scope well thats a choice you need to make, I have Bushnell Trophy seris 1.5X5 on a few slug guns, and on my Remington 11-87 I have a Leupold VX-II 3-9X40. Good Luck!!!!
