You’re right. Missed that he sent it back. I’m still calling BS. What evidence would be left behind that would determine it was ammo related? I always wonder that. They say they won’t honor warranty if reloads were used. They weren’t in this case, but how would they even know? Do they take some sort of chemical analysis of the frame to determine the powder that was used? I highly doubt it. It seems to be an easy excuse to avoid making good.

Bottom line, it’s a 10 month old gun with 100 rounds through it. The OP says it was factory ammo. Unless they can determine it wasn’t or they can determine some over charge of the ammo, honor the warranty and move on. They’re not even gonna notice the minuscule loss of profit if they replace the gun.
