5.7x28 口径手枪看来是家防利器

关于5.7x28口径手枪在胡德堡事件中的惊人表现

[1] 一共1 3人死亡，其中1 1人被击中躯干死亡，这可是当兵的，不少人穿14号鞋，人高马大，这么就被轻易灭掉了
[2] 死亡的13人当中有3个人向医生冲来，被击中躯干放倒，没有机会靠近，说明5.7x28小花生米的止退力惊人，绝对超过9mm
[3] 受伤的3 2人没有一个有能力反击，没有一个被击中躯干，可见这种高速小子弹的威力，我估计不少人最后被截肢了
[4] 侯赛阴医生最后是在被五发9mm子弹击中后被制服的，丫没死

这种手枪后座力小、容量大、初速快、威力巨大，follow up shot很容易，威力界于手枪和步枪之间，只要对手不穿防弹衣、不用步枪，就不容易吃亏，再装个红点就是妥妥的家防利器

我不知道候赛因用的是什么子弹，大概是ss198之类，弹头只有27 grain，大约1.8克，奶奶的。

If you look at this Wikipedia link and look at the list of casualties, one can come to a very eye-opening conclusion.
Fort Hood shooting - Wikipedia, the free encyclopedia

1. 11 people were shot center-of-mass (COM), one was shot in the stomach and one was shot in the head. All 13 died. All 11 victims who were shot COM did not survive.
2. 3 of the 13 people who died, tried to charge Hassan, but he stopped them with COM shots.
3. The 32 people who were wounded were hit in the arms, legs, hips and shoulders. None of the wounded survivors were shot COM.

The following conclusions can be drawn:
1. The FN 5.7 is a very lethal round CQB because all 11 victims who were shot COM died. No survivors for those hit COM.
2. The FN 5.7 is a real stopper, because 3 tried to charge Hassan at close range and were stopped by COM shots.
3. One of the fatalities was shot in the stomach, and died. The fragmentation of the SS197R round can create a hail of metal shards that can cause serious internal organ damage and bleeding in the stomach.
4. None of the 32 people who were hit in the extremities, hips and shoulders were able to muster a counter-attack because the FN 5.7 must have shattered or broken bones. The high rate of wounded vicitms to fatalities was the direct result of the shooting ability of Hassan (or lack thereof), and not because the 5.7x28 round is not lethal.
5. Sgt. Kimberly Munley (base civilian police), one of the first responders, was immediately disabled with 5.7x28 bullet shrapnels to her wrist and a second 5.7x28 bullet broke her femur. The light 5.7x28 commercial ammo showed that it can shatter large bones due to its velocity
6. According to medical personnel, there was so much blood in the room that it was difficult to get to the victims because the floor became very slippery. One can conclude that the commercial 5.7x28 rounds can fragment or tumble, causing immense blood loss.
7. It took five bullets (which I assume was a 9 mm) from Sgt Mark Todd to stop Hasan. And he survived his wounds (no available info on where he was hit, except that one of the bullets paralyzed Hasan).

5.7口径的ammo还比较少吧，我是没有用过。我查了一下与9mm的对比：

Is a 5.7 more powerful than a 9mm?

Ballistics of 5.7x28mm vs. 9mm. Something you'll notice is that the ballistics chart shows 9mm produces less muzzle velocity and greater muzzle energy than 5.7x28mm and maintains them both longer. So while the 9mm is a bit slower when it's fired, it doesn't lose velocity as quickly as the initially faster 5.7x28mm
