We have two S&W M19 with the 4" barrel for sell. Both are used, made in the 70´s, but in nearly new condition.
Problem is, when your fire 50, 100 rounds with Magnum loads, suddenly the cylinder is blocked. The source is, that the gas ring went a few tenth forwared.
It´s angry, a customer came, testfire the gun and bring it back. We knock the gas ring back into the cylinder and the gun work for the next 50 or 100 rounds.
Is there´re a trick, to control this?
It´s only with .357Magnum rounds. With .38Special the revolver works.

Thanks,

Martin

PS: My dad give this both revolvers now only one chance. Then he put it to scrap.

"gas ring"??? you've lost me on that term. I do know that the S&W model 19 was never recommended for shooting continuous magnum loads in. They will sooner or later develope cracks between the cylinder chambers from the stress and heat due to their thin cyl. walls. Are you sure that bullet material isn't shaving onto the forcing cone and building up to the extent that it is jamming the cyl from rotating? I can't tell without seeing the gun and checking the alignment of chamber and barrel.

Gas ring movement is a known problem with the M19, especially with the Federal 125-gr load. I don't know of any solution but I'm sure that an expert revolver smith could help.

You might want to check with S&W. During the '70s many police agencies had similar problems with their Mdl. 19 revolvers when used exclusively with .357 loads. As stated above, the M-19 was never designed for a continuos diet of .357 but rather to shoot .38spl and the occasional .357s. The L-frame S&W was the cure.

If you have to shoot .357's, shoot 158grn loads. The 125's recoil a little faster and seem to be harder on the revolver.

Regardless, Model 19's were more or less made to be carried in .357 but practiced with 38spcls.

The great thing about S&W revolvers is practically everything is replaceable for a price. If you can't find a good revolver mechanic, contact S&W's custom shop. They should be able to perform whatever work you need done to fix them.

I have a Nodel 19 that will lock up the cylinder after a number of shots and prevent the cylinder release from opening the cylinder. Is that roughly the problem you are having?

The problem I found was that the ejector rod was remaining stationary as thr cylinder rotated and it backed out and jammed the cylinder.

In the later models they put the opposite thread on those and as the cylinder turned it actually titened the ejector rod som it woudn't bind up.

The solution was to rotate the cylinder by hand in the opposite direction and the ejector rod would then reduce in legth by screwing back in and you could remove the cylinder. The fix was to thoroughly clean all the parts and locktite them when you re-assembled them. That should hold them for sometime.

No, that´s not the problem. You can open the cylinder, but the cylinder will not rotate. The gas ring went so much forward, that the cylinder is blocked for rotation.

But thanks to all for helping.

I'd call S & W and ask about a factory repair. Hard to sell a gun that one can not shoot!

I recommend you contact these S&W warranty stations. The gas ring has been moved from the cylinder to the yoke and back. There may be a solution more simple than expected.
Good luck.

Yes, it´s very hard. And the customers are meaning, you want deceive.

Thanks, armorer,
but Wischo doesn´t exist any more. The new company name is "Waimax".
We don´t want spent to many time and money for this two guns. We want to sell it for 250.- - 300.-€. Prices are down, after the last school shooting and the following anti-gun hystery of the German governement. Last year, alone in bavaria the citicans took 40000 guns to policestations. The goverment instruction is, that all of this guns, go to scrap. Everybody want to sell guns. Nobody buy one.
Today, I send a e-mail to S&W. I will see.

I have put a several thousand rounds through a couple M19's and one short barreled 66 and don't recall ever having this problem, but it has been a while. I have had the ejector rod come unscrewed and jam things up on several S&W's. Almost all of my shooting has been with heavy bullets though. I will have to look at my notes tonight and see if I have ever had this occur. Replacement parts are available, maybe a little of the right type of Locktite?

I agree that setting the gas ring so the cylinder will properly rotate, after applying the correct Loctite, may be the remedy. For a few dollars it cannot hurt. A machine shop may have some on hand and help out with a few drops so no expense is required.

Try emailing the S&W factory for advice. Whoops, I see you have. Please share their response as there are many models 19 and 66 owners who would be interested.
