I can promise you that if you slammed your bolt, the firing pin would have fell. I back my trigger off, lightly close the bolt, and it is normal. I can run the bolt, slam it, and the firing pin will fall. I can hit the side of my stock and hear it fall. I can bump test it and hear it fall. When it pass those test, it is safe to me. There are several ways to check to see if your trigger is safe. You obviously didn’t. Glad no one was hurt. No need to get *Rule 4 Violation*y over your or your gunsmiths mistake.
