If anyone is interested in getting into 3 Gun this is a pretty good video from a beginners perspective, a lot of videos are by sponsored pros and they jump right in expecting you to have some experience and it can be bewildering for guys first starting. This guys talks through his first experience.
Its a real fun hobby that teaches you real world skills, a lot of people get put off when they see guys running set ups that cost thousands but you really don't need that to get into it and have fun. If you find you like it then you can look into the more high end gear, and tinkering with triggers, mag wells, all that fun stuff.
Best advice I can give is find out where theres one local to you and have look out there, you'll find people there are happy to talk to new guys and help them out.
This was a pretty basic course, but you never know how they're gonna be set up, plenty of different courses and scenarios to keep you sharp and train different environments. You get anything from a basic set up like the top video with the beginner right up to crazy shit like the Duskin Memorial shoot they have at Ft Bragg which is more physically demanding.
Jerry is the best, he's a real gentleman and a legend in the sport.
