No I never put in any lighter searbar return spring but i do alter the strength of the original sear bar spring.
Easaly done with a few strokes with a hammer.
I have changed triggersprings a few times but that is most often when there is a none original triggerspring in the gun.
The weight of the triggerpull is adjusted by the following factors.
1. sear engagment ( adjusted at the sheetmetal piece on the trigger)
2. sear bar return spring.
3. trigger spring.
I NEVER USE ligthend firingpin springs, there is no use for it as the harder the firingpin spring is the more distinct the triggerpull gets.
I don't use set screws, cause if the triggerpull is correctly adjusted the trigger will stop at the frame.
And that is very good cause a screw can move, but the frame will always stay where it is.
Sometimes I change the trigger pin, but i really try to avoid it as its a lot of work.
But if the play is to much in the triggerpin it might be necesarry.
