I picked up a Smith and Wesson model 1000M shotgun this weekend. I am looking at doing a thorough cleaning and I did not get any schematic or manual with it. I am not all that familiar with taking shotguns apart so I was wondering where I might find a good schematic for it? I know that Smith and Wesson did not make this gun, I believed they imported it from Japan. I would be interested to hear from anyone about its reliability and quirks. I was going to possibly get parts from Numrick if I needed them. Any other places that might have parts for this gun especially barrels that I should look at?

Do not soak the action in solvent or use a spray cleaner. The gas system uses a rubber ring/washer that is easily rendered into tar-like goo in the presence of Gun Scrubber or the like. Once the washer oozes into a tarlike substance, it gums up the magazine tube and is a real PITA to clean out.
Overall, they're really quite decent shotguns. I've owned several and was very well satisfied with them. Barrels are not the easiest to come by, but if you can luck into a barrel with removable chokes (they use WinChokes, by the wat) you'll be set.
Many of them came with some really pretty wood.

Old thread, but since I found it looking for info on *my* Model 1000, I thought I should post what I know from first-hand experience and from my recent research.
I just bought one of these, used (of course) in great looking condition. Actually, my wife bought it (yea!) and I 'cleaned' it for her before her first outing with it. Unfortunately, the gun has some problems that you might encounter if you buy one used. Having said that, the quality of manufacture on this gun is just amazing, and the design of everything, from the stock, to the trigger group, thru to the bolt, barrel, and gas operating action, is just phenominal. Much thought and careful work went into making everything fit together with great precision and straightforward simplicity that bespeak of an informed and enlightened designer. I hate to say it, but the Japanese obsession with quality is quite evident in every detail.
The first problem I encountered has to do with the Piston Shock Absorber. Apparently, the rubber material used to make this part was susceptible to the usual gun cleaning solvents in use back in the late 70s/early 80s when this gun was in production. There were no "synthetic safe" versions of popular gun sprays, as there were no polymer guns yet (at least, not in widespread use AFAIK). So, when folks cleaned the gas piston system, at the fore end of the magazine tube, they ended up melting their piston shock absorber washer and the goo ran down into the magazine tube, gumming up the works. Some of it ended up near the front of the tube in my gun, causing the piston to not slide so freely as it should. The result is FTEs and FTFs.
Cleaning it out is described in an article at Brownells, here: http://www.brownells.com/.aspx/lid=10571/guntechdetail/Quick_Fix_For_A_Mossberg_1000. The Mossberg 1000 they show in the article, and the S&W 1000 that I have, are identical.
For what its worth, I used ChemTool B-12 Gas Treatment as a solvent to clean out the gunk, dipping a 12 ga mop in it and swabbing the tube from both ends (leaving the magazine follower in the tube, but removing everything else, eg, spring, retaining clip, etc). It works great! and it's cheap.
Secondly, you might need to replace the melted shock absorber. I just went to the hardware store, bought a 1 foot length of heavy-duty black rubber hose of the right diameter (drain hose? Not sure but it looks "tough"). The hose should OD at about .900-.920 inches. Then cut a nice 0.2 inch length of hose, and use that for the replacement washer. Works great!
Thirdly, my gun came with a missing ejector! The ejector just drops in, between the bolt and the receiver, on the left side of the receiver. I think the previous owner forgot to put it back after the last cleaning. Duh! I have a part on order from LSG Mfg., Inc. http://www.lsgmfg.com/. We'll see how she works when the part comes back.
So, if you find one of these at your gun show or gun shop, and you are attracted to the nice way it swings and points, do pull back the bolt and look for the ejector present, and take the forearm off and look carefully thru the slots in the mag tube for evidence of melted black rubber goo...
