SIG gunsmith question

[Claymore33]

After cleaning SIG P226 , I decided to watch UTUBE video of how to clean firing pin assembly. There are 2 springs in that assembly.

How often do you dedicated(and frequent) SIG shooters replace those springs. every 1,000 rounds, every 2,000 rounds?

5K on recoil spring, 20K on firing pin and spring, extractor and extractor spring - per Sig guidelines at my early 2000 armorers class. Other springs within have various recommendations.
