他有把X5 drop in 4lb，应该还有潜力，打磨不够挖煤

320不是就trigger group算枪吗？drop in的不是等于换了把枪？

哎，是啊，gg贼的很。。。

那这么看，花400块等半年，也就降1磅，这也太划不来了

关于是不是GG很贼，我看有一个人是这么说的，我觉得有一定道理。(难道这些赛枪design时就不考虑这些升级的需求吗？感觉Apex等等aftermarket公司就是在hack厂家的系统，发现一个破解漏洞就造出一个aftermarket产品)
"I believe the reason they have a 300 dollar trigger job and use special parts that they don't offer to the public is because it is difficult to retain the safety of the pistol.  I could be wrong about that but in their video for the pelt system they talk about maintaining the safeties and how they accomplish that in different ways when they do their in house kit.  Makes me think they just can't release it for legal reasons. Again I could be completely wrong there but I agree there has to be a reason and that makes sense to me. "

三把枪都有。GG Drop in trigger 换完简单打磨扳机4磅， 多打磨可能能再降点。 不过Sig客服很差，自己动过会Void Warranty. 还有要换roil spring & guide rod. 4个21发弹匣都不能打比赛用， 17/10发弹匣 40多刀一个。  

Stock 2 改完自己都快变半个枪匠了。G34是上手最快最容易的，成本也最低。打倒后来还是觉得GLOCK最实用，简单明了，特别是打IDPA单双动，外置保险，手动Decock这些东西太复杂分心容易出错。

stock2打磨，换弹簧成本其实不高。就是要多试组合，反复拆装。

完全升级大概需要300刀， Titan hammer, one-piece sear, Bolo, firing pin, extanded firing pin block, 再加 reduced power sear spring trigger return spring, trigger plunger sping, opitmized firing pin spring, Wolff extra power extractor spring ,8lb recoil spring, grip用 CGW Floating Trigger return pin 拆装简单很多

另外一把 CZ shadow2 楼主也可以考虑啊，扳机改起来更容易，只要换弹簧就行了，打磨会更好。

之所以没太考虑shadow2主要还是有点小贵，另外没有fire pin safety，心里有点小别扭。再就是我有一把sp01，不太想有多把类似的枪，想试试不一样的

在BEnos看到的：“The Fix is easy: just remove a small amount of material from the bottom corner of the factory base pad or use the Springer plus two extensions before heading to a major match.”

这样就“废物”利用了吧？

I got my trigger pull gauge just now.  Did a 5 pulls to get an average and ended up with 2 pounds 9 ounces.  All 5 pulls were pretty consistent with the lowest one at 2 pounds 5 ounces and the highest at 2 pounds 11 ounces.  I consider this a very good sign as the trigger is stable.  I think I'd be a bit worried if there were extreme spreads in weight.  I did find it impossible to get consistent pulls on the flat trigger by itself so I had to put a rubber band around it to keep the gauge from sliding all over.  I placed the rubber band so that the gauge would pull from the middle of the trigger.  So I've got about 200 rounds though it now and it feels very consistent.  Here's a couple pics.

Looks like I won't get my spare parts to work in the shorter reset and over travel until next week so that will have to wait.

本来很多比赛改动就是一定程度降低安全性和可靠性的,这个在改的时候大家心里都再清楚不过了.....
包括改glock的striker spring, 各类手枪reset spring, 还有FPB spring,CZ safety ver甚至直接去掉FPB,射手在进行这些改动之前都肯定对枪支结构有一定的了解,并且做好了思想准备.所以安全不安全这方面真是没什么好说的....

这是他改trigger的详细步骤，他在前一页上将来着，但挺复杂，都是细致活儿。
First thing to clarify is that I'm not a gun smith so anything I write is based only on my back ground in mechanical engineering.  I do not have any formal firearms background.  Now that that's out of the way, I believe what dictates trigger pull weight and feel on the P320 is the various leverage geometry's, sear face, sear springs, trigger bar spring and then friction surfaces.  More or less in that order.  The geometry of the trigger assembly as a whole is fairly costly to change (requires manufacturing new parts) so I started with the sear profile.  It has an angle to make it difficult for the striker to unintentionally slip but this is IMO the cause of a few extra pound of trigger weight and creep/mushy feel.  Using very fine stones for knife sharpening, I reduced the angle of the sear face a little at a time, reassembling to test and disassembling for additional reduction.  Of course it's critical not to go too far.  At the same time, I found that using just one of the two sear springs provided enough sear return weight while knocking off trigger pull weight.  I then tuned the trigger bar spring by gently bending it to also reduce trigger pull weight while not going too soft as to eliminate an autable and tactile reset.  Finally, I lightly pollished friction surfaces where it seemed relevant.  I do feel that this has the least amount of effect as Sig designed the friction surfaces to have minimal surface area already.  I wish I had my gauge to provide an exact pull weight but I should get that tomorrow.  I believe it's about 3 pounds but just as importantly, the take up is smooth to a defined wall followed by a very, very crisp break.

So all I really want now is less over travel and a shorter reset to make this trigger perfect.  I believe this can be achieved by changing the profile of the bottom of the sear where the sear resets.  This is also where the trigger resets.  I think if I shorten the height just a bit, I think it will cause the sear to reset sooner, closer to when the striker is released.  Right now, there is a rather large gap in timing in which the striker releases and then the sear resets.  This is why P320s double click.  Technically, all of them do it, you just don't notice it in all of them. Anyway, if the sear reset is reduced, it will allow me to add to the trigger stop which will reduce over travel.  This should also cause the trigger to reset sooner.  I should get my spare sears to play with in a few days so I'll let you guys know if any of that works.

BTW, I accomplished all of this with my VP9 and I'm about 10K rounds though it now and the trigger is as good as when I first tuned it.  I am confident the reliability will be the same with the X5.

打production 和IDPA 弹匣太长了，不能fit check box.

昨天比赛有机会试了其它人的X5，确实是塑料枪里最重的，特别是heavy barrel很不错，因为是non reciprocating weight, 所以在控制recoil上很有优势，而且不影响cycle speed.

那把X5装了gray guns的drop in.  扳机确实有点重.  和我一开始打的MP9的apex类似但还更重一点，手感在3.5到4磅之间。如果能降到3磅就很完美了。

那轴线方面呢？还有弹夹人家是怎么处理的？换成17发的？
我昨天正有机会试了试P320 Full size(没有X5)，感觉手感很好，recoil感觉很小，比我同时试的XDM Competition好太多。印象最深的就是准，7yard很随意就是一个洞，10yards 2"不到。

打production是不是只能改内部，不能换扳机了？
