Everyone is armed all the time and that’s normal, but to draw a weapon is an overt hostile act. A standoff therefore is a game of chicken because both want to kill each other and you want to draw first to have the highest chance of surviving, but even a bandit will hesitate to add a felony murder charge to their rap sheet. The whole town serves as witness when there is a pair of eyes behind every shuttered window. The hero always draws second, both demonstrating his superior skill and speed by defeating the opponent even at a disadvantage, and getting away with murder scot-free.
In eSport where the only physical movement is a couple mm of their hand that may be true. In the physical world where these things involve several inches or more of movement with large muscle groups…ehhh no.
Gunfighter hypotheticals aside you can watch it play out in the real world during any soccer game. The attacker who makes the defender react to them slips past while the defender who makes the attacker react wins. The attacker who makes the goalie react has an open net, but if the goalie can make the attacker react then they block the shot (or it misses).
No matter the physical sport, Soccer, Basketball, Rugby, Volleyball, if it has 1 v 1 elements then “juking” works and the reason why is because it makes the other player reactive.
I saw a youtube of a modern cowboy shooting at stuff.
His hand is already near the gun, like in western movies.
When the signal comes, Iirc he simultaneously bends his knees, gets in kind of a hunching position and barely pulls the gun out rotating it in hip height towards the target and shoots.
Unfortunately, I have no link nor a name to the channel.
It really isn’t like it’s depicted in those pirate movies or the aristocratic era dueling movies.
