Even back in 04-05 I was usually one of maybe a maximum of 3 people shooting a single stack (in limited 10) at different area USPSA matches and even at the state championship I think there were only four of us. I can’t imagine the numbers have increased that much since then.
One final edit:My 1911 heresy is that I do prefer railed models over non-railed, for both functionality and aesthetics. If you’re gonna have a full sized pistol in 2021 it ought to accept a light, because the dark is scary.
