500 S&W Issues.

[Wyomingnight]

Looking for some advice, I have the 500 S&W SS in the short 3" barrel, and shoot pretty heavy loads out of it ( over 500 grains)
I have been running issues with the double action, sometime is fires and sometime not using the double action.
Single action no problem- just seems like the hammer doesn't come all the way back and the cylinder doesn't turn all the way.

I can keep trying to fire it (double action) and sometime it work fine but generally once or twice in the 5 rounds.
No gun smith shop around here really and looked it up on you tube and this seems to be a common problem..

Any help I would appreciate. The gun is about 9 years old, and I keep it very well cleaned.

Welcome to the forum.
Have you checked for light or misaligned firing pin strikes on the primer?

Are you saying no DA trigger pull cycles right, not even the first shot, or are you saying follow-up DA triggers are the problem.

Generally the 500 is loaded with large rifle primers which require a pretty stout hit. Make sure that the strain screw is tight. You could also try replacing the main spring. It might be a little tired. I can't say I've had a problem like yours but then I don't think I've ever fired mine DA. You're a better man than I am.

Are you saying that the hammer falls before the cylinder locks up in DA?
If or when that happens, does the firing pin strike centered in the primer or does it even hit the primer at all?

Could sound like your 500 might have a timing issue. If so, that should most certainly be corrected before shooting it anymore. Especially with such a powerful cartridge as 500 Magnum.
