YES! But not always: Many people sell off guns for too many problems.
People are very fickled and look either for something better or more dependable. Beware of buying a used, inexpensive, Turkish made shotgun.
A few are OK guns, but like Forest Gump said; "It happens" just try not to step in it.
Mid to high priced guns have their share of too many problems as well.
It really is a tough call, sometimes people get tired of playing ping-pong with service departments shipping back and forth, the problems never go away.
Personally, I would stick to names and models you can trust, like older Benelli's, definitely Rizzini = F.A.I.R. or B-Rizzini, Browning 425s or 525s, Special Sporting Clays edit., B-Montefeltro's. There are many guns out there you can trust and justifies the price or value. Take for example Beretta older 682 or the 680 series, many 390s, A-400s, Fabarms L4S are very nice.
But for heaven's sake, do your research on models and types of shotguns you are interested in. I personally would not buy a CG, Perazzi, and most semi-autos, they can be very finicky in models.
And even after you buy the gun you want that's only part of the expense, the other part is making your new purchase fit you.
I would put your trust in Coles, Echons, Pacific Sporting, etc. try to avoid sales on G-B, G-I, etc. Look for a certified used gun for your protection.
In my opinion. Mike
