S & W 1000 Question
I picked up a model 1000M at a sale. It looked good and the bore was clean and shiney, but when I had a chance to shoot it, the gun would not cycle. Does not eject shells either. When I broke it down for inspection, I noticed that tube was full of stuff that looked and felt like tar, very thick and sticky. Any idea what might be going on? I haven't tried to shoot it since I cleaned all the guk out.

the s&w 1000 has a 'piston shock absorber, pt #366640, gunpartscorp.com' that turns to goo after 'x' number of years and some gun oil. this is were you are at. you need to clean this out and replace the p.s.a., it looks like a short lenght of rubber hose. 0 -
Hello,
That goop used to be a buffer for the gas piston. I have repaired a large number of these, so maybe I can help. That goop gets down in the mag tube and needs to be cleaned out. When one of these comes
in my shop, I have found the easiest way to do this is to unscrew
the mag tube out of the reciever and remove the gas piston etc.,
then remove the little keeper that holde the mag spring in. Now
remove the follower by lining up the cuts in the follower with the
detents in the mag tube and push it out. Then get some MEK and clean
the mag tube. Be sure to protect your hands while using the MEK and
use it in a well ventilated area. The reason I use this stuff is because its the only thing that I have found that will really cut this goo out of the tube. Once everything is clean, reassemble and you will need to cut a new buffer out of a piece of leather. Use
an old leather sling or something around that thickness. This buffer
will go on top of the mag spring retainer so that the gas piston will bump down into it and keep from damaging the mag tube. There are slots on each side of the mag tube where some battering can occur
once this buffer melts. If there is any, you need to smooth that
as well. Other than that, since you have an "M" model, you will
probably need to shoot heavy loads for reliability. Sorry so long but I wanted to try and be as specific as possible. Hope this helps.

so im to understand that the use of leather will eliminate the goo from ever happening again? it is the substitute for the rubber buffer? wow! that would be a break thru! 0 -
Ok, thanks a bunch. I did manage to get the goo out with lots of Hoppes. So, am I right in thinking that a piece of leather will take the place of the Piston Shock Absorber? Or is that another thing all together? 0 -
i suggest you get the proper part, the p.s.a. is almost 1/4" long x about 7/8" dia., a piece of leather wouldn't be this thick or provide as much shock absorbsion. 0 -
check the bottom of the reciever were it meets the BBL...
we just had one come into the shop that had cracked at this juncture.
the gun had been neglected and abused, but i thought i would pass this on anyway.
best regards, mike.

I'm with Mike Wiskey on this one. The factory buffer serves 2 purposes, one as a shock absorber, and it has to be thick enough to keep the piston pin from beating the mag. tube(at the bottom of the slots). Two, it's a compressed fit to keep the shock absorber washer from getting turned sideways and tearing up the piston. This is what happens when the shock absorber turns to goo and doesn't glue the washer to the mag. spring retainer. The idiot I got mine from apparently didn't know this! Cleaning solvent,oil, and time is what melts them. If you need a new one, www.e-gunparts.com has them for $1.50, buy a couple so your gun won't end up in a parts bin.

REPAIRMAN, HOTSHOT18 says the mag. tubes were installed with Locktite. Do you have any "tricks" you can add to get one out? The tube is junk and I already have a new one to go in it. Please see this thread. http://forums.gunbroker.com/topic.asp?TOPIC_ID=111162

THE ONLY WAY TO SOFTEN LOCK-TITE IS WITH HEAT, BUT SPARINGLY. 350 DEG. f +- SHOULD DO. 0 -
MIKE, I just busted it loose! Soaked it for 2 days in WD-40. Now I find out Howa did seal them with something like Locktite.I thought this new tube would be a screw-in, but looks like i have to fit it to get the gas ports lined up. Thanks for the help.

Sorry for the delay on answering some of these questions. For Bobski, yes, the leather has worked fine. You're right, it doesnt turn to goo. Like I said, use a fairly thick piece of leather. For TRAP55, I use a tool from Brownell's specifically for removing mag tubes. I also use a little heat to soften the LocTite. Very LITTLE heat. AS for using the original replacement part, I agree fully if its available. I see no reason not to use it, other than in a few years you'll have to do this again HEHE. I started using leather because I couldn't get the original part. So far I've had no ill effects, but if I can get the original part, I'll use it instead. Hope this helps.
