I've been working outside in the heat for the past 3 days with my LCP in my 5.11 Holster shirt under my left arm. I pulled it out after getting home today to find that there was rust on the back end of the barrel (exposed through the ejection port) as well as all along the right side of the top of the slide. OUCH!



So to try and get rid of the rust before more damage occurred, I disassembled the pistol and took a CLP-soaked Scotch-Brite to the affected areas to get rid of the rust without doing too much to the finish. Unfortunately, there is a little pitting visible on the barrel, but the rust itself seems to be gone. Once I have this pistol broken in properly, I'll be treating it with Microlon Gun Juice which should help keep rust away. Here are the after pictures:


Lesson learned. From now on, the LCP gets cleaned and oiled after any day when it may have been exposed to sweat.
