发帖数: 2803 | 3 手枪的穿透能力也很强。几层sheet rock一般是没问题的。霰弹枪即使是buckshot，单颗弹丸的穿透力不如9mm，根据box of truth的数据。
喜欢用rifle家防的话又怕穿透，也许可以考虑subgun，至少可以用手枪弹。或者frangible弹头。
我自己真的打算找找7.62x39的frangible了。上次看貌似都是out of stock。 |

发帖数: 287 | 4 彈頭（bullet）
彈頭基本上是一個投射體（projectile），它由裝藥燃燒後產生的大量高壓氣體急速膨脹
推射出槍口，一旦離開槍口，它在飛行中是處於半穩定狀態，直到和目標接觸為止。由於
人體密度是空氣密度一千倍以上，彈頭在進入人體後就開始滾擺，這是它最基本的運動模
式。
彈頭依其跟目標接觸後的狀態分成三種：實心型（Ball），擴張型（Expanding），粉碎
型（Frangible）。
實心型（Ball）
彈體或為實心鉛製的一般彈頭、或是內包鋼芯的穿甲彈、甚或是含有燃燒劑的曳光彈或燃
燒彈，在外面通常有一層金屬層完全包住（full metal jacket），不論是哪一種，在命
中目標後只會扭曲變形，不易擴張或粉碎。因此這類型的子彈貫穿力很強，但是阻滯力（
stopping power）比較差。由於 1899 年海牙公約的規定，目前各國軍隊都只能使用o型
彈頭。
擴張型（Expanding）
在彈尖的設計上或是使用平頭型（Flat Nose）、彈尖中空型（Hollow Point）、軟頭型
（Soft Point）、異質彈尖型（Silver Tip or Bronze Tip） |

发帖数: 11737 | 6 老邱你上次那个炮口为何不加防尘盖，还有这次这个都是没有google就来，有失水准
粉碎型
粉碎型（Frangible）彈頭在擊中目標後會立刻粉碎，由於彈頭材料是質量较低的金屬
或者陶瓷，所以能將動能一瞬間傳遞在目標上。這種彈頭貫穿力相當微弱，甚至連貫穿
厚重的衣物都有困難，但是阻滯力很強。粉碎型彈頭跟擴張型彈頭一同被國際公約禁止
用在軍事用途上，然而它們在反恐行動中卻有很大的用處。例如在拯救人質或反劫機的
行動中，低貫穿力的彈頭可以减少擊斃人質或是貫穿機身造成失壓的可能性。FBI的人
質解救特勤小組（Hostage Rescue Team）就配有此類彈藥。 |

The question is often asked, “what is the best handgun for concealed carry?
” There are many valid answers to this question and they usually begin with
, “well, it depends on a number of factors.” However, in my humble opinion
, there is one universally valid answer, and that is, “it is the gun that
you have on you when you need it.” With that said, the purpose of this
brief article is to make you aware of twelve handguns that are so easy to

However, the government has to do so though taking huge risk.

JHP一般防身吧。或者是特别追求枪口稳定性的。很多靶场不让用吸铁石能吸住的。听
说RPK有的靶场变态到不能用铅弹，只能用frangible。道听途说，可能是卖子弹忽悠俺

tell you a particular model gun is “junk” and enlighten you as to why they
have made the only logical purchases)…
