It's not like opening a pizzeria. People can get a pizza every week forever. They only need to take a course one time. Your area will reach a saturation point sooner or later. I've been seeing this happen in several areas.
I do think thats a good point, but I just know there is a lot of guns being sold out there last black Friday I stopped by Sportsmans Wayerhouse and the gun counter was packed you would have to take a number. I also know there are a lot of gun owners out there that have never taken formal training... I bet they are a majority even on this forum. I think the ticket would be to figure out how to convince all these untrained gun owners to take a class. I see a lot of fragmentation in the gun training industry... maybe something needs to change there to help standardize good instruction and certification from poor. I don't know just thinking out of the box but I do know there is a lot of gun owners out there that have never taken a class... that needs to change. Kinda sad to think about actually.
