The bullet is a 9mm Luger with the R-P head stamp indicating point of manufacture from Remington-Peters. What is unfortunate, I do not know when or where this particular lot of ammo was purchased. I do know that I have not purchased Remington-Peters ammo within the past 5 years.
After noting that defect, I did inspect my ammo stock looking for more R-P head stamp markings and for any sign of cartridge deformity. That cartridge was one of four remaining live rounds.
While case inspection is necessary prior to reloading a case and final inspection of the finished cartridge is necessary after reloading, it is a good idea to do a quick visual check of all your ammo prior to use.
It is likely this round would not have fed into the chamber and possibly jammed the semi-auto slide creating a potential hazard condition.
