I've been going through my blend of Mobil1 oil, Mobil1 ATF with a bit of STP added to increase viscosity for well over a decade. It's a good general weight oil for rotating parts and intricate action parts (CZ 75 sear cage assy).
For slide rails, I use synthetic wheel bearing grease in summer months and synthetic engine assy lube in winter months. Sig rails, or any other aluminum rails, get greased regularly.
I tend to run guns a bit on the wet side generally with the exception of carry guns. Those get properly lubed, then wiped down well. I don't want to have to answer to oil spots on the wife's new furniture
