In keeping with the theme of this thread, over this weekend I attended my second and third ever official USPSA club matches, drawing from appendix concealment. My first match last week was with an outside-the-waistband strong side open. There was some good-natured commentary yesterday (in reference to something a high-level shooter did at a major match, named Travis McCamish I think), and no issues raised or confusion during stage procedure yesterday or today at all, despite everyone else wearing an open belt.
Venue for all three matches was Rio Salado Sportsman's Club/Usery Pass Gun Range, in Mesa, Arizona. Here the results on Practiscore.
