I normally wipe down any gun I carry all day at the end of the day when I take it off. I always take the grips off my revolvers and make sure there is no moisture under there. It's hot and humid here much of the year and I sweat a lot. Stainless will start to discolor in one day with me. I have never had any problems with corrosion and when you consider that this piece of equipment is carried to defend oneself from serious injury and/or death, it's worth a few minutes everyday to keep it in top condition...isn't it?
