first one approx 3,7 (in 3,5 I has about 0,5% light strikes)
second 4pound (because new ratchet running)
both 625-8 in IPSC - shooting slowly so rebound spring is fast enough
if your DA pull are consistent (6 time same - with cylinder yoke closed) check if you have some burrs at red marked area
burrs jamming closed setup and thus increase the friction

0,12" notch
retail approx. $50, possibility of customer size of the notch (for surcharge)
the hammer will fall down when is betven trigger and frame 0,08 to 0,085" space
btw
the weld-on material is up 50HRc hard by micro TIG techology
(for repairs at the molding forms)
final shape by diamond tips with Dremel

you can compare trigger pull when you adjust same hammer pull with different bent MS
I mean that change is almost at the theoretical level, just by changing the load vector at the end of spring
bent spring will be working closer to the middle part, where have higher energy by stronger profile
negative will be higher nonlinearity of trigger pull
that will be all time ballancing betveen comfort and relliability
60-70% of DA trigger pull is trigger rebound spring (individual, it depend how fast trigger rebound shooter need)
most important things for reliability and effectivity is
1/ reducing friction of hammer
2/ hammer bobing
3/ well primer seating
4/ reducing firing pin spring
5/ perfect flat clips
6/ extending track of the hammer by weld-on DA trigger tooth
I´m sure I forgot something
"just a hair longer " strain screw you can made by trimming head from thread side
btw
straight shape of MS1 type(flat profile) cause jamming of strirrup
because the MS1 is too long for low tension adjust
,493"to ,494" are factory SaW pins I bought from Midway and using with slight modifications
FP spring from ,012" wire 6taps .18" long
trigger reb. spring made from J frame Wolf mainspring (.925"long ,193"OD ,15"ID)
DA pull approx 3,6 pound
