So you've shot a lot of people with your 5-7 and this is how you know this?
No but think about it. The 5.7 mm round is a scaled down version of the 5.56 round. It is designed to have a high muzzle velocity to penetrate modern body armor. Meaning that you are shooting a very small bullet (~.223 caliber) at a very high velocity. That means it leaves a small hole and goes straight through the target, which also means you might risk over-penetration and hit something you don't want to. And completely ignoring ballistics, 5.7 ammo is very expensive and probably illegal for civilians to own seeing as it is
designed to defeat body armor.What you want in a manstopper is a hollow-point, low velocity, and large bullet as seen in the excellent .45 ACP cartridge, which is why that cartridge has been around for close to 100 years. The .45 instead of blasting straight through the target, with the hollowpoint will "mushroom" which creates a larger surface area once the round hits flesh. What has a higher chance of hitting a vital organ, a 5.7mm round (To put that into perspective, airsoft bbs are 6mm) or a close to half inch round? Plus the .45 will not blast straight through the target, reducing the potential for collateral damage.
And to the guy who said 5-7 rounds have higher stopping power than a 9mm is wrong. Against body armor it is more effective but against the average unarmored thug (the most likely target for your carry weapon), it won't be as effective as even the "weak" 9mm (whose stopping power with hollowpoints is more than adequate for stopping the average robber/mugger). The only advantage a 5-7 has against unarmored foes is that the little 5.7 mm bullets can be carried in quantity, but I personally would rather have a 1 shot knockout like a .45 or .357 magnum then having to shoot my target 3-5 times to actually stop him.
EDIT: Ok there IS civilian ammo for 5-7s, go figure but they bullet is tiny (40 grains @ 1950 fps = Energy of 461 joules, and this is for the
hollow point version of the round. The 9mm standard round nose = energy of 483 joules for the
lightest FMJ loading, meaning the standard 9mm no hollowpoint or anything has more energy than the heaviest 5-7 hollow point. The mighty .45 ACP hits with 559 joules with the lightest hollowpoint bullet, and it travels almost half as fast at the 5.7 round. To sum it all up .45 ACP > 9mm > 5-7. And if you still think a 5-7 is an effective man stopper you can google this info your self.
Nice guns Jameson. Can we get a video of them shooting next time you're at the range/competitions?
