I have followed post here on the forum and have gone as far as I care to with sear nose and tumbler notch. Still very hard pull. I did make the mistake of not centering the trigger lever far enough back. The sear engages about 7/16 back of pin center. Any suggestions as to achieve lighter trigger pull. This is a single lever trigger on a Kentucky flintlock pistol. The lock is a Manton.
 
Placement of the pivot is the most critical factor. Are you convinced that can’t be changed?

I would not be working on the sear nose or tumbler. Make sure the end of the sear spring arm that bears on the sear is not jamming up against the pivot.

Next you can very judiciously reside the thickness of the sear spring working arm. By not more than 20%.
 
There's no way you can drill a hole for the trigger pin 1/8 inch behind the existing hole?
I know there are some single triggers that don't have much material supporting the trigger pin but if you can drill a new hole 3/32" to 1/8" closer to the sear arm without the hole breaking out of the material around it, that would do wonders for decreasing the force needed to pull the trigger.
 
Sorry Zonie I didn't make it clear this trigger is attached to a plate.
So is it possible to bend the sear arm forward a tad as it presently drifts buttward. Appears I could gain at least a 1/8 inch if that is possible.
