The huge demand for firearms & increased interest in firearms/2A issues has made "unscripted" basic cable shows like Sons of Guns & American Guns very popular.
1st off, these TV shows are fake, color water jugs or sparks are not going to fly up every time you shoot a firearm. The shows are produced for entertainment and are not quite what you will see in real life.
I'd start with a simple .22LR DA only(no cocking or single action) type revolver like a Ruger LCR or a simple stainless steel S&W revolver in .22LR.
Take a safety class or two & understand your area's gun & use of force laws.
If you want to get a concealed license or carry a firearm to defend you be fully ready to use lethal or deadly force. If you can't kill someone or honestly feel you could not operate a loaded firearm in a high stress event then DO NOT carry a gun.
There are classes & training videos out there but it's REAL not a Hollywood fantasy show.
