I have been carrying the Ruger LC9 as my primary daily carry weapon. 90% of the time I use the DeSantis, Intruder holster and it works great. Latley I have noticed that I am getting rust spots on the slide in three locations, as well as on the mag release. Is anyone else having this problem, or does anyone see this as a sign of concern? I am on the fence about sending it back to Ruger, and I make sure to keep the weapon, cleaned and well oiled. Any suggestions?
