Can anyone tell me about this? It has rifled bore which I found kinda odd. Does that mean no buckshot and such? It has a 20" barrel and the guy wants $300 firm. It looks almost new.

Pictures?
Rifled barrels are only for slugs, buckshot tends to spin out of control and the patterns go away real fast. Not even worth trying in a rifled barrel.

Gun should be fine if you have a need. Can always change barrels to a 20" riot style or a 28-30" field style. Extra barrels can be bought from the Ohio factory, E-bay, Gunbroker and even sometimes at the local gun shop. Also check Gunparts in NY.

You need to specify whether it is one of the DS's with the fixed barrel, etc.

Such as this one:

I have seen shorter/fixed barreled DS's on the market like the one above.

My 2 have 24" barrels.
