Not to be overly simplistic -- but Browning makes about 25 models of their Citori lineup of guns -- that range in price today from about $ 1,750 - to around $4,000 ....and in a wide variety of specs for field shooting, Skeet, Trap and Sporting Clays. The barrel connection on all the models are identical, I think ?, and the barrels, firing pins, springs, ejectors, etc look like they are all made to similar specs .... adj combs, quality of wood, etc are part of the difference... But when someone says "Citori" ...I always wonder which gun they're talking about ?
I also would never say Browning doesn't have an issue once in a while ...or Beretta ...etc / but hands down, I think you will find a Browning or a Beretta will give you a much better long term shotgun than anything made from Stoeger, CZ, etc ....and I think that is seen in the used gun market today on both the Browning and Beretta O/U's.
What none of us can measure on these cheaper O/U's is the quality of the steel in the receivers, barrels, springs, etc ....but for my vote, until these less expensive guns can prove they will last ( where 95% of the guns they make ) will perform with no issues for at least 50,000 shells ... I won't trust them / and I will continue to buy and shoot my Browning O/U's.
