So I got a Ruger SR9c right after Christmas and have been carrying it ever since. Yesterday while I was packing it up to fly back from Florida to Tennessee I noticed what looks like little rust dots on the slide towards the front sight. The gun has only been carried for a little less than two months, mainly in TN and a week and a half in FL. It seems like it shouldn't be rusting yet. I oil the sucker inside and out every time I clean it. Before the Rugar I carried a Taurus 24/7 Pro for three years and it's never showed any signs of rusting. Is the metal on the Ruger just going to need to be oiled more often?
