So I grabbed my spare mag carrier this morning for my EDC (same S&W 3913LS that I’ve carried since 1995ish) and saw this sticking out of the pouch: That’s not good! That happened since my last range trip just a couple of weeks ago. It’s a common failure mode of the plastic baseplates, at least on the single-stack 3rd-gen Smiths...the plastic gets fatigued and splits along the interior groove where it slides over the flange of the mag body. I immediately went on Brownells and threw a few 3913LS baseplates in my cart, but I realize that could have happened just as easily to the one in the pistol. If you carry mags with plastic baseplates, get a flashlight and check then for fatigue cracks every once in a while. It would suck to have that happen at a bad moment. Gratuitous old-school pic (not my current carry load, though).
