The ammo was Cor-Bon 115 gr. 9mm +P. I have shot at least hundreds (if not thousands) of rounds of Cor-Bon in 9mm and .45 with no issues, although it gave some light strikes in a North American Arms .380. I switched to Winchester JHP in that gun, which solved the problem.
I started using Cor-Bon because that is what the gun rags of the 1990's raved about. Now that I have the ability to check DocGKR's sticky threads, if I recall correctly, he is more concerned about accuracy, reliability, and availability with 9mm JHP, since most provide decent performance. As I use up my supply of Cor-Bon, I will likely move to something from one of the larger manufacturers, most likely a 124 gr. +P.
