It's been a while since I read the NSCA rulebook, but is forgetting to take a gun off safe an allowable malfunction? I believe in NSSA, the shooter is required to do what is proper by the instruction book, then, if the gun doesn't go off, it's an allowable malfunction. Leaving the gun on safe is a lost bird. I have automatic safeties, non automatic safeties, and no safeties. I don't shoot in competition with automatic safeties. They are a lost bird waiting to happen.
