Question for the group: How often do you clean your carry magazines? I ask because it honestly never crossed my mind until I did a training class where I was dropping them in the dirt over and over on shooting and reload drills. I decided to give them all a good cleaning and noticed they were full of lint from daily carry. Lesson learned. I've never once had a mag or pistol related failure in thousands of rounds through my plain old unmodified XD40, but this was a wakeup call. A little compressed air and they were good to go, and I learnedly something without having to discover it through a failure. Now, each time I clean the pistol, the magazines get a little love as well.
