Get Jerry Miculek's DVD on Advanced Revolver Shooting from Clark Custom Guns.
Then start shooting ICORE (International Confederation of Revolver Enthusiasts)
After 20 years carrying a revolver in LE I thought I knew how to shoot a revolver............that is until I started shooting ICORE.
Rules, courses of fire, Clubs, and up coming matches are listed on their website.
Like any other discipline of shooting sports, once you show up, you'll meet lots of people to help you get started, tips and coaching, and equipment you need or more important, DON'T NEED.
You don't need fancy guns. I shoot a stock M-64 Smith with speed loaders and my old duty holster.
Have fun, show the guys that revolvers can still shoot.
