Good question! I visually inspect and wipe down my carry piece daily. I remove it from the leather holster at the end of each day and allow the holster to air out, wicking away any residual moisture (leather attracts and holds moisture from the atmosphere, from your body, etc). I shoot monthly, and that means that I burn up what is in the magazines that I have been carrying and replace it with fresh ammo.
After 40 years of daily carrying, it is kind of like brushing your teeth! Just part of the daily routine around my house.
