Wise Lite Sterling 9mm Problem?

[IslandTimes]

So I've had this Sterling 9mm for a couple months and it never gave me any problems. Recently sold it to another guy and he said that the barrel chamber is so loose that it ruined his brass, and wants me to buy a new barrel for it.

I don't reload my brass so I never really paid attention to the condition after shooting it, and while I don't doubt him, I wanted to know if any of you have experienced similar damage to your brass. Is this a normal thing with Sterlings, or is this an defect that I should take care of?

Exactly how is it ruining the brass? Bulging the cases?

Machine guns as a rule ain't particularly gentle on brass.

Would help if we could see some examples.

I'm not sure exactly, he didn't elaborate, but I'll try and get more details in the morning.

Casings could just be bent. My K31 tends to work over them case mouths pretty good.
