Scott: I bought one last year and absolutely love it. Stoeger is owned by Benelli, and yes it uses the same Montefeltro recoil operated action as the Benelli M1. The fit and finish on my gun is the same quality as my buddie's M1 Super 90, although his is a synthetic stocked gun. There is essentially zero difference in fit and function between the two shotguns. The Stoeger 2000 is by and large a Benelli clone (I won't call it a knockoff, because it is built, marketed, and sold by a subsidiary of Benelli. Mine ran $389, new in the box, and has some very nice Turkish Walnut on it. The checkering is allegedly hand checkered, and there is no visible overuns. It eats everything that you stuff in the magazine, from light Remington target loads to 3" steel duck loads.
They are pretty much a steal in today's market, and usually don't last very long on dealer's shelves around here. They have established quite a favorable reputation in a very short period of time. They are made in Turkey, in a factory owned and operated by Benelli Armi.
The weapon should come with 3 choke tubes, and disassembly and vice versa is exactly like that of the Benelli M1. My only complaint is that the anodizing on the takdown nut/magazine cap is pretty sorry. Please let me know if you need any additional information.
