The IDPA equipment survey indicated only 0.8% 40 and 10 mm usage, World Championship.
Also, Glocks were the modal EDC and 85.7 % had carry permits. In another thread, someone mentioned that he thought many competitors didn't carry. Don't know if that was a different 'game'.
I once asked if USPSA did an EDC survey, and a 'gamer' here had a massive shit fit about the question.
