I have a question that many of you shotgunners probably will offer an opinion about... The new Tristar G2 shotguns have labels on them saying to run a box of high powered shells through them for break-in. I bought one of them in 20ga and it is still new in the box at my home. Two days later I found another shotgun that I would like in preference to the G2. SO now I have question about marketing the G2. If you were in the market for a new Tristar G2 shotgun, and you found one from an individual still new in the box. Would you rather buy it after the seller broke it in or new in the box? Do I go ahead and break it in or sell it still new in the box? I ask because I have never sold a gun not knowing if it works properly. What d you say?
