Such as? It was flawed in that the parties were expecting an attack and I could think of other scenarios that they could have run, but knowing how much experimenting they do "off camera", I think it was as good a test as could be and still be TV-worthy for a wide audience.
Oh I've got a laundry list of flaws. Where to begin. Ok, let's start here. At the beginning Adam mentions that he has to use a modern gun replica because they couldn't find a revolver that shot paint pellets. Even if that's 100% true, which is suspect, he further ruins the premise by making is own holster. Now either you plan to do a full "wild west" style deal, or you forgo the wild west for modern scenario. The whole thing was couched as wild west. OK, let's assume that's the foundation. And let's assume you really can't get a paintball gun in revolver. (why not use airsoft?) How many revolvers do you know of require you to rack a slide? Revolvers are either SA or DA. And odds are any gunfighter who's survived a fight or 2 is going to prefer a DA because it's more reliable in the heat of battle, cause even if you can't cock the hammer you can always pull a trigger. So more than likely this would be a DA revolver. Which means no need to cock or slide anything. Then to make it even worse, he makes a crappy non-fitting holster that isn't set up like a gunfighter with a notched front. Then to insult us even more, he goes for typical stupid hollywood showmanship and switches the gun half way through to a ridiculous Desert Eagle mock-up that doesn't even fit his original holster. And he doesn't even know how to use. No wonder he kept hanging up on the barrel.
So we have a guy who doesn't know what he's doing using a gun that doesn't fit the period in a holster that doesn't fit the gun trying to draw down on a guy with a knife. Now let's talk about the knife side a bit. Are you really gonna allow someone to face you down with a knife and NOT draw your pistol? If he's 20 feet away and he's got a knife in hand and threatening me, I've already got my gun out. I may not point it at him, but you can sure bet it's in hand and ready. So it would have been better to force the knife guy to be "holstered" as well. Take the time to draw and run just like the gun. As soon as you see that arm move and him coming, you're on your gun.
Now let's talk about the gun position again. How many gunfighters would you suspect head into a gunfight without a round chambered. How many do it now? I'm betting none. And how many have the safety on? Remember in the episode Adam makes a point of mentioning the safety is on. Heck even if you don't pull the gun, you're probably going to at least thumb the safety before anything goes down.
So either this is a wild west quick draw, in which case Adam should have had at least DA pistol. OR it's a modern version in which case he should have had an adequate holster and rig with a round chambered. And to top it all off, Adam didn't move. How many modern defense classes teach you to stand perfectly still when being rushed? It's all just so full of holes.
Just for kicks, I went back and tested myself against the 16 foot mark. Cue'd up the tape and ran the drill with my gun. (empty of course). Chambered a fake round (dry fire) and holstered it. Waited for the start, and followed the action. I was able to draw and fire before Jamie made it 6 feet. (and I suck btw). SO I thought maybe it's just the chambered thing. So I went back, no mag, no round, and put my empty gun into it's holster. This would make me have to rack the slide and fire. Once again, I'm no expert, but I was able to draw, rack and fire by the time Jamie made it to within 6 feet or so. Long enough that I thought, wow, I could have probably got 2 or 3 shots off even. Now, would he have got me with the knife? Maybe, but when you combine the draw and side step motion, he might have only gotten my shoulder which means I live. Even though I'm probably hurt. (remember, Adam even mentioned that he was faster when being attacked because he was motivated more.)
And none of this takes into account the training aspect. I know for a fact that if I was staring down an elite trained person with a knife, he's gonna get me. He's just better than me and he'd have me before I blink. And vice versa. An elite trained guy with a gun is gonna be all over a nut with a knife. But I bet a moderately trained person could take on the moderately trained knife guy and stand a better chance. Granted both are probably gonna get hurt. Bottom line in my mind is, it was just super flawed. Why not go with the California Open Carry options and see who wins. You know prior to the new law. Unloaded and magazine in a pouch. I bet that wakes up some of the fruits and nuts out there.
