I'm an over oiler. My rifle cases have oil spots inside. My AR15's spit excess oil on me when I shoot them the first few rounds. My pistols have wet spots here and there. My clothes sometimes get oil spots on them.
One of the spots put a drop of lube is on/in the grip screws. I then use a brush to distribute it around the inside/outside of the screw head.
Got back from a five day road trip Sunday (several states) and took my CZ85 Compact clone. Carried it everyday, whether driving, riding with relatives, shopping or just hanging around the house/deck. Carried concealed, right side.
Got home Sunday afternoon and when I pulled the pistol out of the holster to put it up I thought I saw a funny spot on the left side grip screw. I meant to pull it back down and take a closer look but I was carrying bags from one spot to another, putting dirty clothes in the dirty clothes hamper, getting the bag ready for the next trip (always packed and ready), going out to visit with my buddies at the dog pen, etc., etc., etc.
The next day I grabbed the pistol down and sure enough, that "funny" looking spot was some ugly reddish brown rust on the left side grip screw. That side of the pistol rubs against my skin on my right side if I'm carrying under a t-shirt (still rubs against a sweaty t-shirt if I sweat enough and am carrying with the t-shirt tucked in and a button up shirt over top that - for looks and concealment of the pistol).
Removed the screw/grip, the rust appears to have been caught early enough that no finish damage, and wiped it off with an oily rag and some extra oil. Wiped down the frame (polycoat is more durable than blued steel, or I might have had rust under the grip, too.)
I just ordered some stainless steel grip screws.
This time of the year, keep a closer eye on your EDC pistol condition and increase maintenance to prevent issues.
I sure would like to my EDC carry Compacts coated with something more durable and rust resistant than polycoat, but that'll be a year or two down the road (most likely).
