Do you guys have any set round count for replacing trigger, hammer, and disco springs?

I’m my experience they outlast barrels and bolts. By the time you put enough rounds through them to worry about replacing the springs you have a pretty well worn gun that might need lots of parts replaced. If that makes sense.

I just throw another whole FCG in when I rebarrel at around 20K rounds. I’m using some flavor of Schmid NP3 trigger. Sionics, BCM, Centurion.
