Regardless how many rounds I fired, every gun I used gets field stripped and the frame, slide and outside of the barrel get a thorough wipe down with an oily rag. No solvents. Ever.
If I fired more than 200 rnds through it I will use solvent inside the barrel only. Then a bronze brush, dry patches and finally an oiled patch.
Somewhere around 2000 rnds detail strip and thorough cleaning and lube.
