M11/9 w/Max-11.
I found a live 9mm round inside the upper behind the bolt. It had a sharp dent on one side of the casing, halfway up the casing, perpendicular to the axial.
The gun was disassembled, cleaned, fired at the range, brought home, disassembled and I found the round. At no other time was the upper removed from the lower. I have the Viper-9 locking ring on it, which needs to be removed to take the gun apart, so I only remove the upper for cleaning.
Any ideas?
