I carry a 1911 on a regular basis and that has caused some wear to start showing on the bluing. Now just general holster wear is not that important to me, however I also have wear around the grips because I shoot this gun at the range a lot too. When I pull the gun out to put it away at night after carrying all day, usually it has a layer of sweat. I always wipe that off right away. But every now and then I see some spots of surface rust on the left grips from the sweat. Of course I immediately take it to my desk and clean it but I am noticing those spots are appearing over areas of light bluing. So the question is, should I have it re-blued of adopt a more regular cleaning and oiling process? Would I send it back to the manufacturer or find a good gunsmith?
