The oxidation of steel! Ambient moisture in the air/condensation aids/accelerates the process by providing a dielectric situation on the surface, and the rust marks, pits, etc. on a pistol can vary by just how the moisture is introduced--i.e., condensation, spattering, or immersion--you'll see different patterns of damage. This one may have been stored in a holster, the freckling of rust damage looks like condensation to me...
