Endshake=problems?

I have a old 6" Smith M19 that shoots pretty good groups, but has a bit of endshake in the cylinder. Is this something that I should have corrected, or should I just keep shooting it until group sizes go to hell? Thanx-

It depends entirely on how much is "a bit".

When a gun does develop endshake, it only gets worse.

The danger is, essentially the cylinder is now "slamming" back and forth in the frame.
This can, and will impact damage the frame, cylinder assembly, and even the back of the barrel.

If you continue shooting it until the groups go bad, the gun will likely have suffered permanent damage by that time.

I'd watch it closely, and as soon as possible I'd install some endshake washers from Brownell's.

If you get Jerry Kunhausen's book on Gunsmithing the S&W Revolvers, you will be able to determine how bad it is, and how to install a washer to correct the problem.

What he said :).

If it's still grouping well, it's not too late. The frame isn't stretched, for starters. Once it is, it's unfixable.

We use to lengthen the yoke to take out the endshake. A mandrel is placed into the yoke to keep it from collasping. It can then be peened (or better) a yoke tool (made from pipe cutter which has been ground down) is used to "stretch" it. Washers are for folks who can't lengthen them.

Any suggestions of a good smith, for this procedure?

Send it to S&W, they will correct any problems most likely for free.

I recently corrected excessive endshake on my M-18 using the end shake washers from brownells. It was very simple and I'm very happy with the results.

Is their a reason that stretching the yoke is a better solution???

"Is their a reason that stretching the yoke is a better solution???"

Washers can fall out when you take out the ejector rod.

I also use the washers in my guns, they have an advantage: they are slicker and harder and reduce friction wear between the end of the crane tube and the cylinder.
