Converting a SBH Hunter Bisley to SBH Hunter…
Hunter Grip Frame KHR00300
Super Hammer KMR04001
Blackhawk Trigger KXR03901
Super Blackhawk Grips (70095) however lots of other options here.
2 ea back screws (KXR01800) the Bisley has hex screws that can be moved over but Ruger uses 2 ea "B" screws/slotted, the 3 bottom screws move over.
The grip panel locator pin 5/32 roll pin, I like to use a piece of solid stock turning the ends in a drill using a file to slightly taper the ends. Doing this trues up the panels better, IMO.
Trigger return spring pin (KXR06300) can be moved over BUT the new parts are easy to acquire, so I don't transfer. FWIW this pin "can be" difficult to move.
Trigger Spring and capture pin move easy
Captured Hammer Spring, Strut & Saddle move over easily.
Transfer bar, Pawl, pawl spring/ plunger, cylinder latch & spring/plunger, gate spring, stay.
