I am interested in buying a semi-automatic shotgun. Its going to be used for duck hunting. My question is in the field which is better? gas or inertia? Ive looked at Mossberg 935 and some Stoeger's. Many of the people I talk to say they would not use a gas operated in the field because it is prone to "fouling", But I just can't make myself spend $1400 on a Benelli, if the gas operated has a softer recoil.
