I typically shoot the 97BD and it does require a firm reload. So I don't think that is an issue.
The first failure was me riding the slide release and the slide not locking back on empty. Once I performed the reload, I didn't rack the slide to chamber the gun and then click no bang.
The second failure I can't explain. I will wait to see if this continues. I don't recall this happening before. The one difference is my reloads, they are rather short (1.075). I will see how the next outing goes (if I don't go back to my 97BD) before I worry too much.
I will say that I'm really digging the GoPro Session. It has let me see what I don't remember when the buzzer goes off. It's light enough not to be a hindrance. I see myself filming more matches.
