the thing is, i don't have to wait until an opponent is distracted.
i don't expect you to believe this, but if someone points a gun at me, i can likely draw n fire before they pull the trigger.
that's how fast open carry is, with the right rig.
For the rest of us, a bad guy's action is always going to beat our reaction time.
If the bad guy's gun is out and yours isn't, you have been dealt a losing hand. It's probably time to take/try to control his gun. If course that depends on proximity.
But if that isnt an option: It seems likely to me the bad guy is still going to shoot you, even if your draw on reaction time beats his action. The gunfight has started and both parties are exchanging shots.
Expect to get punched in a fist fight. Expect to get stabbed in a knife fight. Expect to get shot in a gun fight.
Why would you want to plan for a 50/50 chance of winning a gun fight?
To me, concealed carry is more practical. The element of surprise may prevent a two-sided gunfight. There's no guarantee the first to get a shot off wins. It's a great advantage, dont get me wrong.
It's one thing to be a great shooter against paper. It's another to be a great gunfighter. Keeping calm under stress, running a gun, clearing malfunctions, avoiding tunnel vision, moving to cover, letting others know you're the good guy, having a plan for once the shooting stops and the police arrive, etc.
You should have a plan in place about when you will and when you won't engage.
