Although I am new to this forum I am not new to working on 1911's and BHP's.
In both these platforms the flat sear springs are often recycled and reused well past the time they should be replaced. These are perhaps the most unloved springs in both platforms.
When I built my current HP from parts I was guilty of recycling these flat-springs and wondered why I would get inconsistent pull weights and Hammer follow at points that should have been safe. Out of frustration with the inconsistency of my results despite my attentions to Sear and hammers I ordered a BHSS Sear spring, and low and behold my trigger pulls became more consistent and the the Hammer follow stopped at lower safe trigger pull weights.
These flat springs fatigue, and just bending them to add or subtract weight is not enough to overcome the metal fatigue they suffer, and often further fatigues an already tired worn out spring. In the case of the HP the sear spring is what prevents sear bounce and Hammer follow. So if your struggling with these issues order a fresh Sear Spring and see if that will not resolve your issues (knowing how to adjust it is vital too).
In my current EDC HP build I could not get my Trigger pull below 5 lbs safely using the FEG sear spring. when I replaced it with a fresh BHSS premium Sear Spring I was able to get my trigger pull down to a consistent 4 lbs 3.9 oz with no Hammer follow after stoning and polishing my hammer and sear on my Powers Custom jig.
Just thought I would contribute my thoughts and observations to the fellow members.
