I'm thinkin removing, the screw #65 does it. Is this correct?
Changing a 52 to double action.

If the trigger is good - DON'T. Will probably never get it back to what it is - based on my screw-up many years ago. A 52 is a 52 for a specific purpose.

The reason I ask is not to make a 52 double action, but to make a 539 single action.....

I would imagine you would need to drill & tap the frame for the screw on a 539.

Yeah, there's definitely no screw hole there, I just need to know if that screw is what changes these frames back and forth.

The screw did just lockout the DA pull on the original 52. But I think they used a different drawbar, sear and hammer on the -1 and -2. Then the screw just works as a pre-travel adjustment. They also remove or don't use a firing pin block or sear drop lever in the 52s', simply using the safety as a hammer block/pin lock.
