Five seveN for military?

loki- this is not a caliber war. It's a friendly discussion about the pro's and con's of a new technological development in firearms technology and I for one find it quite interesting. Afterall- The purpose of this forum is for enthusiasts such as our selves to congregate and discuss the topics that interest us.

We can all ready see from this discussion that in specific situations where enemies may be armored the Five seveN may be a good choice in a P90 SMG. However as a last resort to stop an unarmored enemy a close range, especially one anxious to blow himself up in order to kill you, you will probably be better off with a large heavy bone smashing round at low enough velocity to manage recoil. I apologize for the gruesome description here but the physical shock of a heavy bullet crashing through bone, organs, and muscle might stop a hostile more quickly than the small piercing wound channel created by the five seveN. Especially when shot placement as you call it is concerned.

It is so very important to remember that shot placement is a really more of a hunting concept. In the chaos of combat when your azz and those of your buddies are on the line there is no such thing as shot placement!! You do not have time to line up for a good clean shot as if you are sitting comfortably in a deer stand. If your primary weapon is down and some crazed jihadist is comming right at you, what you are going to do is raise whatever pistol you happen to have and start pumping rounds- if you are well trained you will may remain calm enough to aim center mass but you may panic or not even have a clean shot. When there are obstructions, arms or legs may be all you can see. A five seven, or even a .22rim fire will punch holes in the bad guy and may even kill him but not before he reaches you or hits his detonator. A heavy .45ACP hardball though hits hard enough that it will usually shock the system enough to physically stop the bad guy. Even a hit in the arm or leg will shatter bone rendering that appendage useless. The key requirement in self defense is immediate incapacitation afterall.

...not trying to start a fight here, just a friendly difference of opinion:D
 
Penetration isn't the same as wound or injury that stops a person immediately, or at least very quickly. As an analogy, the needle of an insulin syringe has excellent penetration capabilities, but my son has survived over 11,000 "hits" by one, and hasn't been put down yet.

Now, if that bullet is designed to cause damage all out of proportion of what its weight and velocity would normally produce in a more normal cartridge, (by yawing, tumbling, fragmenting, or upsetting, then that might give pause for thought. However, if it is just a .22 Magnum magnum, then I would probably pass on the idea.

Fixed it for you. Sorry but you can not compare full metal jacket vs full metal jacket and then switch to compare full metal jacket to HOLLOW POINT. So I fixed your picture for you.

...because they only penetrate 5/16 to 1/2 inch. an insulin needel dosen't even reach the muscle.

The US Military dropped fully auto in favor of the three round burst because spray and pray sent a lot of ammo down range without hitting anybody. Controlled, aimed, burst fire is more effective.

The picture was oringinally intended to cover uses where jhp rounds were acceptable as well. The problem I see with your image is that in all the gel tests I've see the 5.7 round spends very little time in complete yaw, most of the time you'll be getting a much smaller frontal area crushing and the permanent crush cavity of the 9mm will have a larger volume. Your image implies that 5.7 keyholes through the whole target and I've seen no evidence of that. If you have some tissue simulant tests showing the 5.7 round spends alot of time in full yaw I'd like to see them though.
 
Maybe the Air Force would like it. Handguns, as a rule, are anemic. The 5.7 vs 9mm debates... someone had a link to the FBI's thoughts on shooting. It added up to the remark that actual shooting results weren't really reproducible, so we can't know for sure whether 9mm or .45 is better, or whether 5.7mm beats them both.
With all the talk about low recoil in the handgun, it seems like the 5.7 might benefit from a selector switch for FA fire. It's already got high capacity. Have a wire shoulder stock that would mount on the back, and it would probably be a great weapon for the folks that usually aren't involved in combat. Full-auto if need be, and pretty good range for a pistol. After all, it's just the Broomhandle Mauser of the new century... and it had a full-auto variant.
