McWood,
The Beretta 390 in 12 gauge was and is a superbly made shotgun. It was manufactured and sold for more than 10 years. I'm not sure, but it may still be manufactured and sold in Europe for the European market.
You will notice that it has a slight angle in the top rear of the receiver. Apparently, the Europeans loved it, but the American market was not as hot as Beretta had hoped, Americans being used to the smooth curve receivers like the Rem 1100.
When Beretta decided to upgrade the 390 to the 391 (with a curve receiver), they had thousands and thousands of 390 receivers in storage. So, they made a special deal with WalMart. They cranked out all of the remaining 390s, using synthetic stocks instead of walnut, and sold them to WalMart. WalMart then sold them at really great prices. Other than the synthetic stock, I don't believe anything else was cheapened up with the shotgun. (No reason to, since Beretta had all of the production parts in stock, and many of them interchange with the 390.)
A friend of mine got one for about $450. A really wonderful buy. Later, he bought a set of beautiful walnut stocks online, for about $225. So now he has both stock sets.
New and used barrels, from 22 inches to 32 inches, are sold in abundance on the internet. The 22 inch barrel, with a cylinder bore, would make a fine self defense piece. Or, one could buy a really beat up trap or skeet barrel for around $80, and just have it legally shortened to 20 inches. Sell the good barrel for $180 and pocket the difference.
99.99% reliable weapon. The ONLY, shells they won't cycle are the ultra light skeet loads (or equivalent light handloads). Everything else goes through like clockwork.
