Economical O/U shotguns are like economical swords. You own one but its not much use other than for decoration. There are a lot of parts and workmanship to go into an O/U for it to work properly. When the price is cut, its also cut by quality and workmanship, and probably not last very long with any amount of use.
When I was in my twenties I took out a small loan for a proper o/u 12g that I've used for the last 30 some years, including competitions, skeet, sporting clays, dog clubs, and 3 decades of field hunting and putting fresh pheasants on the table. The guys who picked up the economical versions from the same time period no longer own the guns or they don't work, and if they didn't bite the bullet for a decent shotgun they spend the same price on 3 cheap ones since.
Like I said, you can have decorative swords or shotguns, or you can have the real thing made for real use. Just my opinion, but my Beretta has never been in the shop in 30 years. I used it twice again last week.
