I had a Browning High Power MK III in 40 S&W. I was new to reloading at the time (1997, early ‘98). I noticed primer flow with bulging cases and the gun did something while I was shooting it. I called Browning and they asked for ammo samples, spent cases, and the gun. An engineer went over that gun and ammo in detail. They sent a full report stating the gun was not damaged, they detected no cracking anywhere, and that the reloads were fine. It was an amazing level of customer service.
Send your gun to Glock. They will look at it and verify it is safe to shoot. If not, they will likely make it right.
