Hi, everyone. I was cleaning my G29 today when I noticed a small crack in the frame directly below the muzzle. This kind of makes me mad because it's a fairly new gun. I've only put about 600 rounds through it. I bought it new and sent the warranty card in. Should I contact Glock directly and get it repaired? I assume it's under warranty. I haven't been shooting reloads or anything through it. Thanks!!
