A little history lesson...
The photo is from the 1981 IPSC Nationals. It's the Top 16 Shooters in the "Man vs. Man" Finals. The guy in the white shirt in upper left hand corner is Ross Seyfried (1981 World Champion) shooting against yours truly. :yup:
Ross started the trend of wrapping the off hand finger around the trigger guard. I shot that way for a while, but then converted over to Hot Shot Shooter John Shaw's stance (John is in the white shirt below me & Ross). You can see the resemblance of stance with me & John.
I can't remember the last time anyone won using the trigger guard finger method (or the Weaver stance for that matter) to win a major match. :icon_neutral:
