Good question. My lube schedule is likely far more intensive than it needs to be. I wipe my duty pistols down and re-lube usually once every two weeks regardless of round count. Every time I shoot my duty pistol or Ar's for training, I clean the weapon afterwards and re-lube. I typically re-lube during the lunch break of any training classes I attend on each day of training.
