I've recently picked up a blued Series 80 MkIV Gold Cup Nation Match in rough shape. I'm just getting into it mechanically, in preparation for rust blue refinish, and I've discovered a "sporting" trigger job.
The hammer hooks are 0.016" long, but are square. The sear nose is rounded off to the point that it's producing negative engagement angle (the hammer moves forward slightly prior to release), and the depressor and spring are MIA. Cocked and unlocked, I can push and wiggle the hammer off the hooks
My questions:
1) Should I recut the hammer hooks to .020, or is 0.016 appropriate for a GC? They are square and otherwise in good shape. I'd rather not buy a hammer if this part can be repaired.
2) When I replace the sear, can I use a standard weight sear spring and skip the depressor. The pistol does have the original wide steel trigger (trigger bounce, etc) but I'd like to avoid trying to find/waiting for the Gold Cup sear and depressor parts; they are out of stock everywhere I've looked. Will the standard sear spring compensate? EDIT: the sear is apparently no longer manufactured as Colt doesn't list it. If a trigger replacement is required, where can I find a light weight trigger wide enough (0.352") for the Gold Cup frame?
3) Does anyone know where I can find a blue thumb safety similar to the stock Colt 'short' that came on this? Colt's out of stock, the Ed Brown and Wilson parts aren't the right shape even after grinding down, and I don't like the oar-sized ambi that it's wearing now.
As always, your expertise is appreciated.
