Ringing noise
I had a 2 frame 12 ga Trojan, and a 12 guage Sterlingworth that rang upon firing. I am not a physicist, but would guess that the ringing is related to harmonics. A vibration that results from strong springs, creating an audible ringing noise. Sort of like a tuning fork. I don't think it is indicative of any problem. Both the Trojan and Sterlingworth performed flawlessly in a variety of conditions, and over a long period of time. Just my thoughts.
