Gunslingers

Often gunslingers in entertainment agree to square off one-on-one, at high-noon, in the middle of a street of a town and wait to shoot until one has drawn their single weapon from their low-slug holster that was modified for quick-draw. This sometimes involves fancy handling of the weapon, spinning it, firing from the hip, or some other flashy theatrics. There is a type of chivalry expected. The good guy waits for the bad guy to draw first.

In real life, most gun fights were unplanned, or at least, unplanned buy one of the participants. Waiting for an opponent to draw first and hip shooting was stupid and extremely rare. If there was waiting to be done, it was for the opponent to become distracted, be drunk or asleep, or to have their back to a shooter. Gunslingers didn't shoot to injure, disarm, or un-hat, they meant to kill their targets. Gunfights were not usually between gunslingers who actually tended to avoid each other for reasons of self preservation. Average citizens with legitimate need to carry a side-arm, such as a lone traveler, an actual cowboy, or law enforcement, would use a soft holster that secured the weapon well. Firearms for protection on horseback, a train, or stagecoach was shotgun or rifle rather than pistols. While 'quick-draw holsters' did exist, it was much more common for gunslingers to conceal their weapons under garments tucked into waistbands or pockets and two have at least two to be fired alternately by both hands at once. Shooting tended to be done from behind cover and was not often a one-on-one event. Gunfights tended to be spontaneous, chaotic, and likely to involve the shooting of bystanders who did not realize was what happening and therefore did not flee or hide behind cover as quickly as the combatants. Gunpowder of the american old west era produced a lot of smoke and it was only after smoke (and in some cases lots of dust) had dispersed that anyone knew what had happened to anyone but themselves. In many of the few cases of recorded one-on-one standoffs where a participant was watching for an opponent to draw, the standoff was usually ended by the participant who refused to draw by walking to the waiting person to attack them bare-handed (they didn't perceive what was happening because they were intently focused on the undrawn gun).

The movie Solo: A Star Wars Story near the end, depicts conditions of a realistic gunfight, except for the alien planet and laser pistols of course, but circumstances and outcome would not be out-of-place were they historical.
