AK vs AR
Here is my take on AK (Kalashnikov) style rifles vs AR-15 style rifles. For
simplicity's sake, I will consider AKs in 7.62x39 and ARs in 5.56x45 NATO. I
own both, and I like both, and I have experience running both in carbine
classes, for whatever that's worth. AKs and ARs have different design

Compact 9mm Pistols for Concealed Carry
We didn't do a "best list" because your personal requirements for a
concealed carry pistol will not always be the same as ours.
The rules for the 9mm CCW list: Weigh 30 ounces or less, barrel 4.1 inches
or shorter, and cost less than $600 from a dealer. Most confrontations will
be at 7 yards or less, so any choice you make from the below list should be

systems include pistol, carbine, mid length, and rifle gas.
16" barrel can utilize both carbine gas and mid length gas system
The closer the gas port is to the chamber, the higher the force that is
applied to the bolt.
By lengthening the gas system with mid length, the bolt and receiver
lifespan is somewhat increased and the felt recoil is slightly dampened.
That is the merit of mid length over carbine gas system.

出借用他的枪打20发体验一下。
口径：.45ACP
长度：6.1", 3.25" Barrel
高度：5.1"
厚度：1.2"
弹夹携弹量：10+1
frame: polymer
slide: steel
night sight: available
这把枪不是特别合适我的手。握枪的时候小指总是放在弹夹的seat上。Grip手感不佳，
可能设计时候对手小的人没有特别照顾。
枪很轻，感觉比G19还轻一些。.45ACP的后坐力贼大，打完一发后居然把手震的枪口向
上60度左右。第一发准确度不错，但是每次把枪口调回射击位置时间长；三次double
tap第一发在9环内，第二发都在6环线上；估计需要一段时间的磨练才能有效使用。
枪的front sight和rear sight都是fixed，但是今天偶所有20发都偏左上，那个老美打
得pattern也是偏左，不知道是sight alignment还是俺们俩人握这把枪的姿势不对。
枪上有night sight，但是大白天的根本看不出来效果。

使用rifle action spring，对整枪的可靠性有帮助，开锁抛壳减少short stroke，闭

发帖数: 11154 | 46 昨天把NRA Pistol Instructor Exam的考试部分提交了，回复是50道题错了一个，而且
是不应该错的问题，贴出来反省一下：
The basic rule for sight adjustment is:
a. move the rear sight in the opposite direction that you want hits on the
target to move.
b. move the front sight in the same direction that you want hits on the
target to move.
c. move the rear sight in the same direction that you want hits on the
target to move.
d. none of the above. |

不算精加工，打磨光滑靠自己多打。
普通M&P，扳机感觉(主要是最后击发)改进最大的还是那个Apex hard sear，也非常容
易换，只需要一个1/8" roll pin punch，同样在Brownells上可以一同买了：

当然还需要榔头啦，呵呵，最好还有几个软木快，破布等垫着就成了。
sear block pin敲出来，sear block拿出一半让sear pin露出来。sear pin是松的，一
顶就出来了，换上hard sear再原样装回就成了。当心sear下面的弹簧弹出来，顺便看
看是不是大号的sear plunge/sear spring。
firing pin block边角笔直而不圆滑，扳机杆推动时比较涩，但一旦顶上去后也就好了
，不影响最后一段击发，你不在乎就不一定要换那个圆滑边角的Ultimate Strike... 阅读全帖 |

发帖数: 3947 | 48 我曾经抱怨过我的sig combat sight picture.甚至差点换掉它。今天突然发现其实自
己已经习惯它了。仔细想想主要是因为终于找到了速度和精度的合理平衡。过去是心理
习惯性地单纯追求精度。眼睛总是在sight和target之间不停扫描好几次才开一枪。现
在基本上精力集中在sight上，USPSA的目标其实都不太远，基本上不太用费劲看目标。
这时候combat sight picture就显出优势了。这个我觉得主要是心理关。
今天还试射了一起比赛的S&W MP和CZ75 shadow
两个都不错，上手很舒服。body index很自然。CZ75shadow比较重，射击感觉和我的
sig没太多区别。
特别说说S&W MP，真的真的很棒。虽然这个是trigger job之后的，但除了trigger其他
感觉也特别好。尤其是指向和复位。我特别加快了速度射击，仍然非常准。真的很喜欢

发帖数: 956 | 49 Q: My SigSauer pistol is not accurate. Why? What should I do?
A: All SigSauer production duty/combat pistols are set up to use a "combat"
sight picture. This is where the front sight completely covers the bulls eye
of the target. Using a six o'clock ("pumpkin on a post") or center mass ("
half'n'half") sight picture will result in low impact. SigSauer, Inc sights
in all non-sporting and non-target pistols for 2.5 inch groupings @ 15 yards
. If you are still having trouble please contact Customer... 阅读全帖 |
