If I'm not careful, my P45 will do it quick. Clean it off, and use Barricade on it after it's clean. That helps tremendously, or get a different holster that covers that area, and has some kind of moisture protection. Or just keep an eye on things and clean it as needed, keep a little more oil than normal there, that's what I did for the longest time with the P45. My P45 is older, so this is not a new thing. I have yet to carry the wife's CW45 more than around the house, so I have no idea if it will do the same.
Attitude: it takes 43 muscles to frown, 17 to smile...and 3 for proper trigger squeeze.
The olive branch is considered a symbol of peace, and good will. Last time I checked, it's still a switch.
