    (Cohland) I really apprecate your comments and you are right. Im a Hands-On/DIY type of guy, and I have always been interested in how stuff works. Sometimes you just have to set there and stare at it and play the motions out in your head and play with things and thats what I ended up doing.

    The reason I decided to do this custom work was because there is a local gun shop here where I live that also runs a beginners compeition shooting club. The owner of the gun shot, who is also the president of the shooting club shoots a competition Glock that has some kind of aftermarket competition trigger kit in which gave it a something like a 2-2.5lb trigger pull. When I asked how much does something like that cost, the owner told me it was $320.00. When I came to from the heart attack I just had I thought to myself, I bet I can get a nice trigger pull by just tuning the gun myself and not blowing a bunch of money.

    It was that and I just remember talking to poeple who just to get a consistant trigger pull, would put the NY1 unit in and make their tirgger pull heavier just to get consistency. Also, I was reading or hearing about when people would try to lighten the trigger pull, the result wouldnt go past a certain weight (something like 4.5-5.5lbs) and with that the pull would be inconsistent. I love DIY and Im cheap, lol but I wouldnt have it anyother way!

    I got the springs in and got them installed. Before the install the trigger was light and smooth but still had a heavyness to it while moving through the trigger pull cycle. The heavyness did cause uneven movement because of heavy friction even though the pull is baby butt smooth.

    But now, with the lighters springs installed, (reduced weight Striker & Striker Plunger springs, & heaver trigger spring) the trigger pull is still as baby butt smooth and is much lighter, and when the pull is started I can just glide through the motion until the Striker is released by the Trigger Bar. The final weight is now 2.8-3lbs, a drop of .8-1lb. I am very happy with the results and cant complain with the little money I have spent!

    I don't know what the trigger pull weight was when the pistol was unaltered, I didn't have a trigger pull gauge back then. But I can start from the 3.5lb Connector install.

    Reduced weight progression & what I did:
    5.5lbs - 3.5lb Sherer Connector installed.
    4lbs - 25 cent trigger job & the procedures outline in the video link posted in post #1 & pictures in post #12.
    3.75-3.8lbs - procedures outlined in post #19.
    2.8-3lbs - springs listed above in this post.

    Enjoyed these posts. I took my G21c to the range yesterday and realized that I have become used to the lighter pull of the 3.5 connector (which I haven't put on the 21). As I was aiming and pulling the trigger, I kept thinking "when is this thing going to fire?". Made me think that the light pull can definitely improve target accuracy. So, I ordered a 3.5 connector and also some competition springs (safety spring, trigger spring, firing pin spring) that I "assume" are lighter springs than stock, it didn't say much about them but they weren't too expensive so I impulsed to see what they would do.

    I have been there my friend and yes lighter trigger pull will difinitely improve target accuracy. The lighter springs make a nice improvement too.

    Great work, Boomer!

    I really appreciate the logical approach and details. Makes me think there might just be some science to this after all.

    Just a note about light springs in Glocks...

    Sometimes a lighter striker spring can cause light primer strikes... Failure to fires... This usually occurs when you continue to use the standard Glock striker... The heavy striker (relative to the new, lighter striker spring) doesn't have enough energy to fire standard ammunition with normal primers... There are two ways to solve this problem... Use Federal primers if you reload... or buy a lightened (skeletonized) striker with an extended tip...

    I've wondered about that. That's a good point to watch out for.

    Another great thread.

    I have to say that I am super impressed with the amount of effort that these posters go through and the fact that they share what they found out to improve the equipment and enjoyment of others.

    Fantastic work Boomer, and thanks again for your info and efforts!

    2 Quick questions...

    Hey Boomer,

    Thanks again for the awesome work you did on the advanced trigger tuning thread. Great stuff!

    I had 2 quick questions for you if you don't mind.

    1. When you bent the part of the trigger bar that the spring connects to, did you heat the metal first? I just don't want to snap one of these by doing it wrong. and..

    2. Did you do anything to the shape of the firing pin safety? Some people like to dome them a little to get more of a "rolling break" feel vs. the wall. I don't know how pronounced it is, but if you put this much effort into your triggers, it might be something to check out.

    Thanks again!

    Been a while since Boomer posted... We try to keep him chained up so he can answer posts, but he breaks loose from time to time...

    I believe you do have to heat the trigger bar to bend it back...

    A round firing pin safety does help to smooth out the trigger pull... I use the Glockworx titanium firing pin safeties... Some people don't like them because they don't last as long as the stainless steel safeties...
