I read the thread. The guy had 20k plus rounds through the gun and 30k 9mm cases lying around. He used up the slide, big whoop. I'd expect wear after that many rounds and not cry about a $500 pistol not lasting forever on the internet LOL
Seriously gun nerds(not accusing the above poster)don't seem to know anything about mechanical stuff. The stuff ive seen people crying about is amazing.
20k+ rounds and he's surprised by wear. He's been cheated! LOL glocks aren't what they used to be LOL
Honestly I don't know, shooting reloads frequently voids your warranty for a reason. Maybe srp does increase wear. They wouldn't be my first choice, but in a pinch they'd do.
