发帖数: 4534 | 1 half cock的作用在1911上是用来防止机械故障导致击锤被意外释放。不能上保险也不
能扣击锤。不是合格的手动保险， 这个状态下击锤更容易受外力影响， 长期使用会磨
损击锤和阻铁。
da/sa的beretta 92也有这个功能，可以缩短双动模式下的扳机行程， 但降低安全系数
， 因为uncocked & unlocked carry本来就没有uncocked & locked 安全， 减少扳机
行程更容易ad.
另外beretta half cock也一样磨损零件， owners manual(for those who cared to
read)里特意写到不要依赖这个feature. |

发帖数: 115 | 3 good swing, some of my opinions:
1. lower body too active. notice your take-away is even initiated by hip
turn(3 and 8 iron back view), it will make your upswing way too inside.
better start it by arm/shoulder turn and keep your lower body as quiet as
possible.
2. spine angle not very consistent during the whole swing. of course it's
quite hard for most golfers.
3. during downswing, you uncock your wrist too early. this will
significantly affect your distance. my suggestion is to slow down your |

另一个问题是finish时的那个右肘实在看着怪怪的:) |

发帖数: 115 | 5 除了hip turn的问题，wrist uncock也早了。这个角度grip看不太清，感觉上strong的过头了。可能这个抵消了impact时候hip/shoulder open程度的不足。不过这种compensation会比较容易导致偏左（挥杆轨迹如果inside-out，可能hook；如果outside-in，可能pull）。关于hip rotate先还是lateral shift先，推荐去看看jim hardy的plane truth for the golfers，一本很好的书。不过高尔夫的理论，都得结合人本身，pro的swings也是五花八门，只是fundamental的一些东西是差不多的。就拿这个right knee来说，以前都说要keep flex，但是这几年很流行的stack and tilt swing(mike weir, aaron baddeley...)，就是要straighten the right knee。反正，多看些书，自己琢磨琢磨，才能figure out什么最合适自己。比较方便的是像ET说的，找个教练，相信他说的，跟着一套练下来。 |

发帖数: 2325 | 6 Pull down with your left hand
More golfers initiate the downswing incorrectly than commit any other single
fault in golf. Almost invariably the cause of the fault is grabbing or
throwing the club with the right hand instead of pulling it down with the
left hand. When the right hand starts the downswing action, the shoulders
move forward, the wrists uncock and both clubhead speed and square delivery
are inhibited. The key thought of pulling down on the club with the last two
fingers of the left h |

我差不多，都是过头。
一点小建议。你uncock太早了，你看看你driver downswing到水平的时候的角度，已经
135度了，power早早leak了。可惜。否则driver还能加上不少yardage。
你的wedge打的很好。羡慕。 |

发帖数: 210 | 8 这swing还是挺耐看的。几个评论的都挺有道理,尤其觉得qiant说的uncock太早。
柔韧性好，不由得感慨- 你们是早上八九点钟的太阳,这个世界是我们的也是你们的,但

发帖数: 155 | 10 not easy, but I always prefer DA/SA over SAO for carry
some DA/SA you can carry cocked and locked (not very safe to me), or can
always be uncocked with one round in a chamber for emergency
for SAO, you must carry cocked and locked for emergency |

发帖数: 155 | 11 你说的好像跟我说的是一个意思 glock跟revolver都是DA吧 我拿DA/SA跟SAO比 就是因
为DA/SA 有DA这个功能 for emergency carry SAO只能cocked and locked. DA/SA or
DAO can shoot both cocked and uncocked
only 20% LEO carry SAO. 1911确实很牛 所以把它当作所有SAO代表跟DAO, DA/SA比有
点那个 我喜欢1911 我也有一把1911 即使这样only 20% SAO
I understand and agree your statement "DA/SA first shot not easy" but it
does not support SAO is better than DA/SA or DAO
不少DA/SA第一枪也很轻 比如walter 更不用提FNX-9 and FNP-45都可以cocked and
locked
总而言之carry SAO只是一小部分 如果不是1911比较牛 SAO for carry 确实没啥好处

发帖数: 32 | 12 确实需要买枪了,昨天夜里被楼上apartment邻居惊醒,好像是掉了个重物在地板上,听起
来就像有人从窗户跳进来一样.当时一下就被惊醒得不能再醒了.本区治安还好,但是如
果真有什么事情发生,那就是除了装睡以外一点办法也没有了.
因为没有任何经验,所以先请教各位大侠,然后找时间靶场试试手,尽快装备上.
初步考虑准备从以下3支枪中(均为9mm)选一支:
1.Ruger RS9C
2.CZ2075 rami
3.PX4 storm subcompact
本人买枪目的纯属预防万一,在不得以情况下的自卫.优先考虑以上三种CCW型号主要是
考虑到它们都方便携带,Ruger和CZ都有可单手操作的safety,弹夹可多可少.
PX4是我最犹豫的,好像是safety单手无法解除,即使能打开,大拇指也是反向,还要再握
回才能射击.不知道PX4在只是uncocked状态下和其他两种在cocked+保险闭锁状态下哪
种更安全携带并且首发射击响应时间更短?
我选枪的思路是否有问题?纸上谈兵错误难免...呵呵.欢迎批评
本人充分知道携枪责任重大,能扔钱包避免开枪就扔钱包,也不会不进行技能训练,但是
万事开头难,请... 阅读全帖 |

发帖数: 5644 | 13 HK的双动的确是又长又重。周末试过几组全双动的，开始几发都不上靶，手指扣扳机到
手变形，follow through就更没准了。后来改成单动，就打出了贴的那张。我当时买带
保险的，就是想象1911那样用。
在适应全双动之后，我又试了uncock，从桌上拿起来打DA，结论是需要很多训练。因为
瞄准和扣扳机是两步。如果是cock+safeon，在举枪到眼前之前，有足够的时间safeoff
，pre-press，准星划过目标是稍加力就好。十码打在六寸圆里我就知足了。结果是这
样不难，比SA速射海简单些。
扳机行程和重量，我觉着大厂想搞，没有搞不好的。但是他们不做，应该是他们的市场
考虑。我觉得如果勃朗宁现在给军警设计新枪，扳机也好不了，但是可能会留很大的改
进余地。毕竟军警主要用于近战，戴着战术手套，那点行程重量差别应该不大。但是要
是手一哆嗦，枪就响了，法律上的烂事讲不清。 |

发帖数: 90 | 14 I used A-bolt 30-06 for a few years.
There is one obvious short-coming on its bolt action: it can dead-lock if
you didn't handle it corrected(just doing coked and uncock). And you will
need a tool to fix the deadlock. This means you have to quit the hunting
trip and go back home .
This is fixed in X-bolt. |

发帖数: 36899 | 15 个人用，除非去比赛，还是选DA/SA安全一点，特别是你的枪没有保险。
DA/SA的第一发正常是uncocked，要更大的力气勾扳机。后面的是cocked
用力小。这个不适合比赛。
LEM每枪的扳机重量一样，比DA-SA中的DA要轻。自用走火可能就大了一点点。 |
