I would think if rules were established and a matches scheduled there would be a pretty good turn out. After competing in ELR Rifle Matchs with my handgun there were several rifle shooters that said they would be interested in building a ELR handgun if there were competitions to compete in with them. It would be like any other sport in its infancy, once there is a commitment to the sport and a few matches shot word of mouth would spread quickly throughout social media and your sport would grow quickly. I do believe that keeping barrel length limited to 16” is key to being recognized as a Handgun Competition and avoid the stigma of being just rifles without a butt stock.I have a few 16'' and under but all of my long range pistols have 18 '' . I would be open to cutting them down if there was a couple matches to attend or more . It seems that WY has all of the matches for this sport ! I know there were shooters from Mississippi , Michigan , Ohio , Washington , IL show up there to shoot for 3 days at Wy shot and then MOA . That scheduling is good for guys that can go one to another so mabey schedule them apart from each other .
That being said I would do both so I wonder how many new shooters would attend on on the east side of Mississippi ?
