Pistol only (fixed sights as well). For guys we have Cap and Ball category and single action. We are doing the same this year for the ladies. We have had anywhere from ~15 to mid 30s on the shooters. i would say it is weather dependent, but it doesn't really deter the die hards. One of the best shoots was cancelled mid way through. Big storm blew through, some ran to their cars and left. Some of us ran to the porch on Zerelda's house. We sat their drank coffee, swapped lies, all in mostly period clothing. It was kind of surreal.
