I only do a scheduled detail strip once per year, at the end of the season (roughly 25-30k for the practice gun). Other than springs, I'm pretty lazy about replacing parts if they're not broken. Examine your extractor, firing pin, and slide stop for signs of failure. Beyond that, just clean it well, lube it up, and return to shooting.
I break out some picks to really dig out any built up carbon during the deep clean.
