Default Cylinder Notch

I have a Model 36 that will turn clockwise when it is at rest. When I got the revolver, used, it would turn on all positions.
I replaced the stop spring.
Now, on three of the notches, I can turn the cylinder clockwise with just a little pressure.
At full cock or with the trigger pulled and held locks tight.
I don't see any damage to the notches or the stop. Just a little shiny spot to the front of the notch.
When I had it apart the stop fit into the notch pretty good.
Could there be a burr i'm missing? Or is this normal?
Thanks.

Replacing the Stop itself and fitting it correctly would probably resolve the issue. Hard to be 100% positive without having it in my hands.

Replacing the spring was a good start but the stop has to be fitted to the gun to work properly. There is a step that is filed to allow the stop to rise in the frame notch. No - you should not be able to turn the cylinder. Also, the yoke barrel could be out of line. As noted, without having it in hand it is difficult to determine the exact problem.

If the cylinder stop ball and cylinder notches are in tact and undamaged, you may be able to let the stop out a bit and solve the problem. (S&W calls this, "stop doesn't hold") Shooting debris embedded in the stop notches can also cause issues, so make sure the notches are clean....use a toothbrush and a little solvent to get down into the bottom of the notch and clean out any dust and dirt there.

As mentioned in the thread above, a small amount of material can be removed from the adjustment step just behind the ball of the stop. This will allow the cylinder stop ball itself to rise slightly higher, and more fully engage the cylinder notch. Approx. .003 - .005" of material is available on the step.

I bolded the line "At full cock or with the trigger pulled and held locks tight" because that seems like an unusual symptom to me. It makes me think that when everything is at rest, the trigger is affecting the position of the cylinder stop. And then when the trigger is pulled back, the cylinder stop moves to a healthier position. If that is happening, I would want to see how the parts interact with the sideplate removed. Seems like a fitment issue.
