Could you give me some examples? Thanks.
Startle response and almost shooting someone for one. I had it happen with a 1911, finger was indexed on the slide, while clearing my house after coming home to find the front door open.
Wife walked in behind me and I damn near plugged her. Fortunately I had my trigger finger indexed and not in the trigger guard.
Was out shooting one time and a guy walked out of the woods (on private property) down range from me beside my target. I was shooting a 625 revolver double action and was able to stop the trigger press before I made a shot.
