Thank you all for the information, it is greatly appreciated. I have striker fired pistols they all make that mark, but not on hammer fired. I did take the firing pin out and clean out the firing pin channel, spring and firing pin block. It's much like the euro. guns that I have. There wasn't a noticeable amount of crud, just oil. Very clean now. I was looking for a new firing pin but to no avail. Now that I am informed that it is sort of normal, I will continue to carry him wherever I may go. I have to have confidence in my firearms to carry them. Once the confidence is broken, it takes some time to get it back.
