Stoeger is NOT made by bennelli!!! the clerk is either misinformed, misunderstood what he was told, or due to KNOWING that these rumors are going round, trying to pull a slightly fast one.
Here's where the confusion is coming from... Stoeger and Bennelli are now both Owned by Barretta. this has lead to confusion. b/c now Berretta, Bennelli, Franchi, and Stoeger, (as well as Uberti, maker of some of the the better italian clones of 19th century american guns) are all under the aegis of BerrettaUSA here in the states. and this leads some to think that they're all the same guns now.
now to list what you saw.
Benelli ALL Italian made and a true "top fo the line" gun and some of the sticker price is paying for the rollmark. but still exceptional guns
Stoeger is stoeger industries, a US based firm. They are the folks who print the shooter's bible, and several other books for the shooting and hunting enthusiast. they are NOT a manufacturer, they are an IMPORTER. same folks who sold the "American Eagle" Lugers
the Auto is a Stoeger 2000, which is a Turkish made gun BASED on the Bennelli Autos, but NOT made to the same hig standards etc. a decent gun but not near the quality of a Benelli from what i've seen. think of them like a Norinco clone of the 870. (i've heard rumors, that the M-2000 was part of the deal for the merge with Barretta, but i do NOT know)
the Condor O/U is i think made by the brazilian firm that makes their SxS guns for them. the initals "IGA" keep coming to mind but i'm not sure if that;s the Maker or an older form of Stoeger (to Many who use the SxS gns in Cowboy matches the company is called "IGA stoeger")
the doubles are great guns, built like tanks and the SxS "coach guns" are much favored by those who shoot Cowboy Action. in this usage these guns get more put through them in a year than most would put through such a gun would anywhere else. and they STILL last for years without much trouble.
so if you want a shootable O/U try a condor out, as i said IIRC both styles of double are from the same brazilian firm, and i'd buy one of the "coach Guns" again in a hearbeat.
But i'd pass on the M-2000 i'm not to enthused about a look alike gun, if it was a gun truly made in a Bennelli factory but less fancy and cheaper "non vital parts" (tricky phrase/concept that) maybe, but not a turkish made knockoff. even at the "around $500 mark there are a heck of alot better guns out there.
