For about the last 9 months, my main carry gun is a S&W 640-1. I work outside the majority of the day in a fairly dusty environment. Every couple of days I wipe down the gun because it accumulates a layer of dust. Ok, here’s my question. Should I be worried that the dust is getting into the concealed hammer and other mechanical components? I’ve searched the internet, but I can’t find anything that relates to my question. Am I overthinking cleaning? I know how to take the cover plate off to access the internal components, but I don’t want to do it on a regular basis for fear of eventually damaging the plate and creating an issue where it won’t seal properly. I obviously want the gun to be reliable if I ever need it in an emergency situation which is one of the reasons that I started carrying a revolver. Any recommendations on how often I should inspect and clean the internal components would be greatly appreciated.
