Josh you should also take into consideration that there are a bunch of avid 3 gun shooters in Missouri, Kansas, and Arkansas. People will travel for a good 3 gun match because it is that much fun and there just aren't enough matches in all areas. We have a few guys venture up to the OKC match from DFW. I am sure you can/will attract shooters from out of our regular cirlce of pistol match shooters if you put on a good 3 gun match that is structured similar to the major matches.
This is a big reason why I made the suggestion about 2 gun matches not always including pistol. All the 3 gunners I know want to shoot their rifle and shotty. Besides, the pistol shooting in a 3-gun match is usually the least interesting. We all know and love high round count pistol shooting stages. Low count pistol usually means hosing a few targets from one spot. We've been there and done that already.
Regardless of the format I will attend when I can, enjoy good company and have lots of giggles.
