I have a bit more complicated revolver I'm trying to convert from da/sa to sao for dros'ing. You can follow my progress and chime in over at Gunsmithing & How To - DA/SA to Single Action Only conversion.

My question is, if you disable the trigger from cocking the hammer can you call it single action only and be done, or does the FFL have to see that when the hammer is cocked, the trigger can release it?
Meaning do I have to present a functional single action only revolver to my ffl to start the dros?
