As one who has never participated or seen a combat competition event, how realistic are they? From what I see on YouTube, the carry openly, which seems unrealistic for most. And, of course, no one is shooting back in such games.
In response, IMHO there are really 2 issues...
? Owning a handgun doesn't make you a handgun shooter, you have to get out and shoot. Any handgun shooting event is better than no shooting event. All these events involve handgun handling, reloading, movement, and of course acquiring the target. Those are all key.
? Obviously we can't have people shooting at the participants, even with paint ball. We have to inject "the clock" to apply the sense of pressure. All the major competitions now have you working against the clock. There's something about the sound of the "BEEP !!" going off in your right ear that gets the adrenalin flowing.
The more fanciful pistol competitions are called
IPSC, and I believe that's what you've been watching. Guns and mags are exposed on the belt. Those scenarios sometimes border on video games. The standard training stages that stress strong-hand vs. weak-hand shooting rarely make it onto YouTube because there's not much action.
The truly defensive side of practical shooting is called
IDPA. That uses concealed weapons and mags. Reloading requires you to move behind a barrier. The guns and scenarios are much more like what you might think of as plain-clothes LEO training. Check it out....
