I can honestly say I've never had this happen to me before. I have shot the crap out of some Sigs, Beretta's, and Glocks to boot. I now have a Shield in 9mm and hope it does not become the first pistol to do this.Have had that happen on most of my guns at one time or another. I bought a small bottle of white acrylic paint in the craft section at WalMart. Clean the area with alcohol then using a toothpick, place a small drop of paint in the hole.
