Where else would we be talking about? Heh, can you even own a gun in any other country without a license (to own, not even talking about concealed-carry)? And honestly I would expect those who carry to use a double-action firearm rather than a cocked single-action. I’m surprised anyone would be cavalier enough to carry a cocked single-action, but I guess we’re talking about people paranoid enough to carry. I would think it’s a common assumption though that you’d carry with a round in the chamber. If you encounter a knife-wielder at 21 feet WITHOUT a round in the chamber, then sure, you’re probably (I refute any claims of “guaranteed” though, since you’re still at least as well off as unarmed) fucked. That’s precisely one of the reasons you would carry with a chambered round. Now, imagine some guy is mugging you with a gun, now you’re REALLY fucked. Against a knife, you might take your chances, they might not be great, but they wouldn’t be zero either. Against a gun, without a round, you’ve basically got a paperweight. With a round, maybe you see a chance to turn the tables by “accidentally” dropping your wallet or something. If he’s distracted he might not notice you draw. He’d probably notice you chambering a round though.
Your friends who were trained in muay thai and went against someone armed with a gun is nowhere near the same situation. Nobody goes to a club with the intention of shooting a couple bouncers. Rare enough that someone would go to a club to shoot up defenseless patrons, but who the hell would pick a fight with the strongest ones there, out on the street where outsiders could see and report it? And if by chance someone did (maybe due to a personal grudge), they would have just shot your friends from a distance. No, they probably thought flashing a piece would intimidate your friends, and it didn’t work, since a gun in the belt is not a threat to someone who is a) trained, b) already within 3 feet of you. Those are far, FAR from the conditions we were discussing. That does not prove your position at all. I conceded in my FIRST post that if the knife were already at my throat, I wouldn’t have a chance. That is basically the same thing.
Most people are intimidated by guns. Most people are not trained in martial arts. People like that would likely give you the right of way (I’m guessing that guy just wanted to get into the club and thought your friends would make way if he showed them his gun) just from seeing a holstered gun. Those are reasonable assumptions to make (though not reasonable for bouncers, so that guy was probably just an idiot). That doesn’t mean everyone would make that assumption, and if faced with an adrenaline pumped, insane knife-murderer at 21 feet, I don’t think anyone would make that assumption, they would shoot as quickly as they were able. And if they had at least enough training to not panic, they would be able to judge whether that would be before or after the knife-murderer reached them and alter their actions accordingly. This might mean spending a few seconds unarmed, dodging knife-strikes, looking for a chance to draw, or it might mean drawing immediately if they were fast enough, but the disadvantage of unarmed against knife (and they cannot be worse off than this unless they’re panicking) would be in endurance. A knife obviously only requires a bit of contact to create a great wound, whereas dodging would likely require more effort. A knife’s sharpness would not be affected by its user’s fatigue whereas the unarmed person’s ability to dodge would.
And a double-action firearm cannot accidentally discharge. This is a matter of the laws of physics. You cannot just create energy out of nothing, and reactions are governed by the laws of thermodynamics. The hammer is not going to cock itself, in violation of entropy and conservation of energy. No amount of engineering (or lack thereof) can violate those rules, else someone would be REALLY rich by now after having created perpetual motion. Something has to physically pull the trigger (and hard enough) to cock the hammer. The only way for an uncocked double-action firearm to accidentally discharge would be for the ammunition to actually cook-off, which is certainly not going to happen if it’s sitting in your waistband or holster unless you’re literally on fire, in which case you’ve got bigger problems. Honestly, everything I’ve read about modern firearms says even a cocked single-action can’t accidentally discharge without someone actually pulling the trigger, but I’ll concede that may be, (MAY BE, not IS) simply pro-gun propaganda.
So, a website selling something said you need this something. Well, my friend, I’ve got some snake-oil you would just love.
