You don’t have to spend that amount of money. I bought a Weatherby Orion in 2001. It has hundreds of days in the field & lots of rounds at the range. It still locks up tight & is accurate. It cost about $1,000 & they still cost about that. And it’s a nice gun. Sometimes you can find them cheaper.
Are you sure you want to go down this rabbit hole The browning citori cxs would be a good choice or the Beretta silver pigeon 1 would be good if taken care of will last him a lifetime I am not sure if I wood give it a steady diet of rain or snow in the duck blind if so you might think about one of the benelli or Beretta semi autos the big question is how often is he going to shoot it? If he shoots it a lot go with the browning or Beretta if only on he shoots it a few times a year on the clay fields you may look into one of the cheaper O&U guns you can get good or bad in any gun in any brand but the browning or Beretta is probably two of the top choices another question is if you drop 2500.00 on a quality gun doesn't mean that he can hit anything with it So my advice is to go to the gun club and see if any of the shooters will let him try out a few guns pumps, semi autos, O&U guns and see how he does
