The S&W Model 3000 was actually made in Japan by Howa, for S&W.
These were very good quality guns, that were basically a "Clone" of the Remington 870 with an aluminum receiver.
After S&W's disastrous Model 916 shotgun fiasco, S&W was determined to get it right this time.
At the time, S&W was making a run at capturing the bulk of the American police market.
During this time, they already owned the police handgun market, and they were introducing ammunition, holsters, handcuffs, and other police gear.
They thought the shotgun would complete the line-up and they would have it all wrapped up.
Unfortunately, as good as it was, the Model 3000 was unable to stand up to the abusive treatment police shotguns get, and S&W was unable to make a dent in Remington's 95% plus of the market.
After a few years, S&W announced it was dropping the ammunition, holster, shotguns and other lines, and was "getting back to our main business of making handguns".
In addition to the Model 3000 pump, S&W also made a Model 1000 auto, a clone of the Remington 1100.
After S&W dropped the guns, Mossberg picked up the Howa-made guns for a year or two, before they too dropped it.
Apparently Howa imported the guns very briefly under their own name.
Although the Model 3000 was unable to stand up to police issue use, for a time the Model 3000 had somewhat of a cult following among individual police officers.
In the hands of a gun owner who takes care of his guns, the Model 3000 was and is an entirely satisfactory shotgun.
Gun Parts Corporation bought the S&W parts, and they still stock most parts and many police accessories like folding stocks, barrels, and magazine extensions.
So, while the S&W Model 3000 was an excellent gun, it just didn't have anything to offer over the Remington 870, and the aluminum receiver was unable to take the abuse in police service.
