HI all:
I have a S&W 638 which I bought new. It always had a problem with a difficult to release cylinder. But now it won't even close - and I'm not going to force anything.
As near as I can make out, it seems to be an ejector rod problem.

Anyway my question is, I figure it's best to send it back to S&W rather than give the job to a local gunsmith. I also figure that S&W might not charge much for this, if anything, were as a gunsmith could charge whatever.

My question is, does anyone think it's not a good idea send it back to S&W and just go the local gunsmith route?
I haven't contacted S&W, so I don't know what they would say.
I'm sure some of you have had experience with this kind of thing.

Thanks for replies
 
1. scrub under the ejector star and rear of cylinder very well with some good solvent and a toothbrush. Take your time and get it really clean.
2. See if the ejector rod is loose at all. If it is, remove the cylinder assembly, insert some dummy cases or snap caps into the chambers, secure the ejector rod in a PADDED VISE, take hold of the cylinder, and tighten it.

If these don't help, contact S&W or your favorite qualified gunsmith.

Both of the above posts are correct.

S&W ejector rods can unscrew slightly, which makes it difficult for the front of the extractor rod to unlatch from the latch at the front of the cylinder. S&W started putting a reverse thread on the extractor rod long ago, so the rod will tend to screw in, rather than out, when the cylinder rotates.

Your revolver will have the reverse thread. So make sure the rod is screwed all the way in by turning it counter-clockwise, the opposite of the way one usually screws anything. First try it finger tight without using any vices. If that solves the problem, there is your answer.

The second thing is that burnt or unburnt flakes of powder can get stuck under the extractor star at the rear of the cylinder. This can also cause problems with the cylinder releasing. Push the extractor rod in and see if there is anything stuck on the rear of the cylinder under the star. If so, clean it out.
 
As already noted, I suspect this is an easy at-home fix.

On a more general note, I tend to farm most things out to the local gunsmiths. This can be very hit-or-miss as there are some terrible "gunsmiths" out there, but once you've found a decent one, you can expect faster and better solutions to most problems, as compared with the repair departments at S&W, Ruger, etc. These days, they only things I send to the manufacturers are gross problems, like warped frames, which really require a replacement rather than a repair.

Bulletski, I've done it, but I don't like shipping a gun back to the manufacturer. I do not like the hassle that comes with shipping a gun anywhere. That's why the steps I take to get a gun up and running again are as follows:
1. Try to fix it myself (sometimes with the advise from good folks right here on THR, or even with the advise I get from calling the manufacturer).
2. Take the gun to a local gunsmith.
3. Ship the gun back to the manufacturer.
 
You’re lucky, a trip to the mother ship in Springfield is a months-long process right now.

I’ve had the ejector rod unscrew on a couple of S&Ws over the years, as you found out it’s an easy-to-check maintenance step every time you clean it :thumbup:.

Stay safe.
 
Use some type of thread sealant or thread locker on the rod to prevent it from occurring again. Unscrew the rod, flush the threads (male and female) with solvent to remove oil. One small drop of thread sealant (shellac, LocTite, nail polish [color optional]) assemble and don’t mess with it for 24 hours.
