Gravity, what you have is what you need.
That smoothbore bbl has a tapered section in it near the muzzle called a choke. This keeps the pellets together better than a straight cylinder would. Chokes come in varying degrees, IC (Imporved Cylinder) is the next step up from no choke, or cylinder choke. It's a good choke for buck and slugs, usually.
Your 870 will safely shoot any common 12 ga load in 2 3/4 or 3" length. It should be marked on the bbl that this is so.
I suggest shooting it some with light target or field loads to break it in, and have some fun while you're doing it.
Check the Archives for info on practicing, ammo etc. Be advised that the more you shoot, the better you get, the more effective you are, the safer you and your fellow officers are. And, being a stone cold deadly shooter with a shotgun aids not only life expectancy, but promotional opportunities.
Good luck and good shooting....
