I forgot to mention an incident I learned of some years ago where an off-duty cop successfully used a 5-shot snub to stop 3 armed robbery suspects (with the first 5 rounds fired). Remember ... "There are eight million stories in the naked city". You can probably find something to agree and disagree with whatever you wished. Train and practice. Practice some more. Then some more. Keep doing it. Might help. Probably won't hurt. 5 rounds might be "enough" ... and 30 rounds might not be "enough".
