第一就是手枪弹明显更短，为了保证短子弹有足够多的弹头重量，所以子弹口径都偏大一点。手枪弹中最普及的就是9mm弹，也有.45口径11.43mm的手枪，这个对于步枪来说都算是大口径了（手枪弹也有小口径，不是一概而论，仅仅是说相对而言手枪弹主流口径偏大）。

The 9mm has about 4 ft-lbs of free recoil, while the 5.56 NATO has only half a pound more, at 4.5 ft-lbs (the 5.56x45 generates significantly more recoil energy, but a 5.56 rifle’s greater mass proportionately absorbs that recoil).

5.56无法击穿IV级的防弹衣，大家如果玩过塔科夫，上面的各级防弹衣是真实的，可能没那么夸张，但是保你命，防止子弹直接秒杀你是可以的。 另外就是其实5.56里面也分类型的。 像 …
