Inertia guns (such as your Stoeger and all Benelli shotguns) are easier to clean and maintain due to the simplicity... Gas-operated guns recoil less, and are more difficult to clean and maintain... Were I to purchase an inertia gun, it would be in the Vinci line... Great pointing weapon, less recoil than the M-2 or SBE-2, and the recoil spring is in the front of the gun (as opposed to the stock) making it even easier to maintain... If I did not go to the Vinci route, I would take a hard look at the Retay Masai Mara... Less expensive, and per the reviews all the gun of the Benelli line without the "Benelli-click." As far as chokes, it depends on the gun, the shot size, and the ranges you are shooting... The majority of my shots are from 30-40 yards, and I really like the Light-modified (LM) choke which is the same as the Skeet-2 (SK-2). If I am shooting at closer shots (20-35 yards) I prefer an I.C.. If I am shooting 35-45 yards I tend to go with a modified choke, and switch to a larger shot size... In most of these newer guns, the extended chokes do very little if anything to improve the pattern, but they are convenient for removal and assertation as to which choke is in the gun. In older guns with shorter choke inserts, the extended chokes (in my experience) actually do improve the pattern (in my old Browning chokes in which the invector is only 1" long, the extended chokes add to the taper and have improved my patterning on a pattern board). My typical shoot (shooting birds at 25-40 yards), I shoot a LM with #4 steel in the chamber, followed by #3 steel in the magazine... If the vitals are showing #4 steel kills birds well out to 40 yards... In the wind, I go with a larger shot size due to the wind moving smaller size shot more (i.e. I use #2 steel in the wind).
