Single Parker trigger vs double Parker trigger
 

I would like to move a single Parker trigger from a 0 frame to a 1 frame and move the double on the 1 frame to the 0 frame. Is this an easy change over ?

Not really. The whole trigger plate would have to move with it too. And the hammers and sears. And the hammers are not the same between the frame sizes.

Putting a miller in the 1 frame would be more practical and save you the cost of modifying a second gun. Your proposal may very well be cost prohibitive.

Thanks for the information . I can swap out triggers if i use the same size frame .
