I currently carry a Taurus millennium pro .45 and i noticed that it is starting to get rust around the slide serrations. To be honest in the summer i sweat more than Roseanne Barr looking at a flight of stairs and i believe that this is the issue. So i guess what im asking is there something that i can put on my firearm or is there a better salt resistant gun that i should save up for, or just wear, as my wife would call it a "Husband beater" under my outer shirt. also has anyone else had this problem and how did you fix it?
