Amazingly, I have never had a misfire of any kind - ever. Be it factory, or my personal loads, every primer hit has resulted in a "bang" for me. Just lucky, I guess. There may be a day, who knows.
I'm doing a TRB simply because I don't want to take the time to second-guess the situation. Fall back on training, as it were.
Last time I was at an IDPA event, a mis-fire happened with a lady shooter. She did the TRB method superbly! I was impressed. And well, . . . it was kinda hot - there I said it
