Depends on your shooting, in my comp revolver I won't really clean it till season is over and some of the guys i shoot with have never cleaned their barrel in 30 years. If you shoot ppc or bullseye with lead wadcutters you don't want to remove the lead that is there because it will effect your accuracy greatly, the cylinder and action I brush clean after each use though. I generally run 2-3k rounds of wadcutters through the pistol each season.
