I recently acquired a pre-lock S&W model 586 with 4" barrel. It is in good shape and I would rate it at about 97% condition. It has the firing-pin mounted on the hammer and has the old-style cylinder release button. I believe it is "pre-dash" because it is stamped "MOD 586" with no -# after it?
It seems to be mechanically sound. It locks up tight with a minimal amount of endshake, the barrel/cylinder gap is about .004", good timing, the trigger is good, and the barrel is exceptionally smooth and looks good.
But I have noticed one thing that is bugging me. And I do not have enough experience with revolvers to find the problem and fix it.
When cycling the action, I can feel that on three of the six cylinders the hammer is harder to cock in SA mode, and the trigger is harder to pull in DA mode. Furthermore, on the three cylinders that have the increased trigger pull, there is hardly any endshake/cylinder play. It almost feels like the cylinder is welded to the frame. But on the three cylinders that work smoothly, there is a bit more endshake/cylinder play.
When cycling the action it feels like this:
-easy
-easy
-a little tight
-a little more tight
-tightest
-easy
What could the problem be? Could it be something minor such as fouling, or something major such as a bent frame?
Thanks,
