I have an S&W "Perfected .38" revolver, and it seems to me that the timing is off. I'm looking for a gunsmith who works on these revolvers. Does anyone have any suggestions as to who I could contact?
For anyone who's interested, here's why I THINK that the timing is off. (Disclaimer-- I'm not a gunsmith.)
I only shoot new factory ammo in it (.38 S&W, which is not readily available-- I reload, but I haven't bothered yet with that caliber).
If I shoot it single action, then each round will go off, and each will have a small, circular, well-centered dimple in the primer.
The same thing happens if I shoot it SLOWLY in double action.
But if I try to shoot it RAPIDLY in double action, then one or 2 rounds out of every cylinder (a cylinder is 5 rounds) will fail to detonate. Those rounds will each show a different, and abnormal, indentation in the primer. The indentation starts in the center and extends radially to the outer edge of the primer.
So I THINK that what is happening is that the hammer is allowed to come forward before the cylinder has locked fully into battery, and I think that the abnormal indentation in the primer results from the firing pin hitting initially at the outer edge of the primer, and then as the cylinder finishes its rotation into battery, the firing pin "drags" from the edge of the primer to the center. Of course by the time the firing pin gets to the center of the primer, it is no longer pushing on the primer with enough force to detonate it.
Bottom line: I'd very much like to get this revolver running the way it should, and so I'd very much appreciate knowing where to send it for work.
