How many rounds through it? Minimum service for many of the parts is 10,000 rounds.

+1....also might want to take a look at pricing on the parts....I don't have ANY friends I like THAT much!!

Common replacement items:

Trigger return spring
Firing pin block spring
recoil spring
extractor spring
roll pin 3 X 14mm HK suggests to replace these EVERY time you knock one out they should be replaced with a new fresh pin.
Mag springs (super common issue)
O-rings (if your firearm uses them)

There may be more but this covers the main wear and tear components. I hope this helps.

I've had my usp for 12 years still haven't replaced anything. I must need to shoot more.
