I currently have a S&W 19-4 .357 and there's an issue with the extractor on the cylinder. The cylinder is very difficult to open, as in tight, and there's a line on the face of the frame like a scratch from pushing the cylinder open. This takes considerable force to accomplish. However, the cylinder rotates freely, and cycles properly. It hasn't been shot much, so i was thinking it just needed to be shot more, well i ran a bout 20 rounds of .38 special through it last night, and when you open the cylinder, and press the plunger to the rear to extract the shells, it gets tight, almost like the extractor is in a bind. It'll make push the shells out 3/8", and then you can manually pull them out, but this isn't always possible. So i loaded up the cylinder w/ 3 shots, every other hole, shot all 3 loads, and again, the same issue, like the extractor is binding. However, once i pulled one case out by hand, then the other 2 dropped out freely like they're supposed to. Any idea what could be causing this? I can provide pictures for referance later tonight. Thanks!

Probaly crud in the cylinder. Disassemble the entire cylinder assembly and clean and oil it and see it that cures it. Also the ejector rod is left hand threads and use 2 empty cases in the cylinder to hold the extractor star from turning while unscrewing it.

I agree that there is likely crud under the ejector or the ejector rod is not totally tight. Clean everything. Are these hand loads? Over cooking them will do the same.

Factory loads. I'll clean it up tonight and see what we've got going on in there.

Look at the forcing cone too buildup there can bump pressures

When i got it out last night, the cylinder opened fine with no extra force like it's supposed to. So i went ahead and pulled the cylinder apart and cleaned and lightly oiled all of the moving parts and cleaned the forcing cone, there didn't appear to be much if any build up in any areas that could maybe cause the issue i was having. It was just strange, all the way around. I'll take it out and shoot again this weekend and see what it does then.

This!
The ejector rod is a LH thread, and deserves a SMIDGE of blue loctite. Dollars to donuts it was working loose a little.
