I have a police 870, 18" barrel, cylinder bore, and bead sight. I'm good out to 50 yards with it shooting rifled slugs. 30 yards was the longest shot I've ever had to take with it. I'd like to get a DRS barrel for it, but with the type of hunting I do I can't justify the expense. Actually what I really want is an 1100 or a Benelli semi-auto.
