I'm really interested in the 870 Express Tactical shotgun. Of course it has an 18 inch barrel that does NOT accept chokes. I want to have the 6+1 capacity and I don't want to be messing with tube extension for the longer 26" 870's. I will mostly be using this shotgun for plinking and skeet shooting but occasionally I want to pheasant hunt. Would I still make out decently with an 18" shotgun with no choke?
