What a difference this spring made! It was about a half inch longer than the one I took out of my pistol. That's how old my pistol is! Now it doesn't experience unfired rounds like it was prone to before.

Suspecting a firing pin problem for light strikes and misfires, another firing pin did not solve the problem. The new mainspring immediately began shooting 200 rounds in a row with certainty. (The pistol had at least 8-10 thousand rounds and over 20 years history.) A friend had to tell me to try a new mainspring. Solved the problem!
