I was going to write something like this but when I went on line to get some details about Glock trigger parts (3.5, 5.0 pound trigger connector and NY1 and NY2 springs), I found the below copied article by Massad Ayoob who says it all better than I could have.

He does not, however, talk about the simple and very effective act of just polishing up the tirgger components as is covered at the web site (sorry I know I have posted it several times before but for continutiy I want to include it here also):

or Google "glock 25 cent trigger job"

Strange, Massad talks about people complaining that stock Glock triggers are too LIGHT! No one in my crowd ever thought so, but we are all people who have grown up shooting tuned 1911 competition guns. All of us wanted smoother, lighter, crisper triggers - more 1911 like, than the "marshmellow" like stock Glock tirgger feel.

I have a 35 that came with the 3.5 pound trigger connector and stock spring. It has been polished and tuned by Glockmeister. I can shoot this gun as good as any of my 1911s, often better.

Side note: My 35 also has a tungsten guide rod (heavy - not IDPA legal) that I put in for carry sometimes, that changes the feel of the gun on recoil - decreases 'split" times.

see "guiderod tec" article

http://www.custom-glock.com/glocktech.html

My 19 is completely stock with the 5.5 pound tirgger connector that came in it, but was just an out of the box gem. I have not even polished it. I guess its a freak.

My sons Glock 19, his carry gun, has the combination of a 3.5 pound tirgger connector (marketed by Glock as a "competition weight") with the NY1 spring and it is a very, very nice shooter. As Mas says below - somewhat like a very good short pull revolver trigger. Massad also mentions that this set up is used by a "midwest city police department". I have heard that the biggest city PD in Arizona also uses this set up, but I have not been able to confirm this. If they do, I am sure it has helped their qualification scores.

Note "trigger connector" is the correct Glock term, but many people also call them "trigger bars" and I likely have in other posts at this forum.

The real story Glock trigger pull weights: Glock critics say its trigger pull is too light. It may be that they've been weighing it wrong

My friend and fellow instructor Dave Maglio is a Glock fan. His department issues him something else to wear in uniform, but he almost always has a privately owned Glock for off-duty carry. When he became the 17th IDPA Four-Gun Master, he did it with a Glock 17 9mm in Stock Service Pistol and Enhanced Service Pistol class, and a .45 caliber Glock 21 in Custom Defense Pistol against the short trigger pull 1911 autos. "Hell," he said, "I would have used a Glock instead of a Ruger GP-100 for Stock Service Revolver if Glock made a wheel gun."

One of Dave's pet peeves is people who complain that the Glock trigger pull is too light. It comes out of the box with a nominal five-pound pull. This upsets some folks who think of that in terms of double action revolvers and autos with pull weights in the 12- and 14-pound range. "People are missing the reality," says Dave. "Think in terms of human engineering. The Glock trigger-pull weights are apparently taken at the tip of the trigger. It's a pivoting trigger design, so the leverage is greater there, and the pull-weight seems less."

He explains, "Look at how people actually shoot Glocks. Their index finger is on the middle of the trigger, where the safely lever is, not at the toe. The middle of the trigger is where we should be taking the measurement. It weighs out heavier there."
I proposed an experiment. Dave broke out his Glock armorer's kit and a trigger-pull gauge, and I unloaded the Black Hills 165-grain EXP .40 S&W ammo from the Glock 22 I was carrying. He then installed every reasonable combination we could think of, and weighed the triggers with each at the toe, and again at the center of the trigger.

Three Gets You Five

Glock sells the 3.5-pound connector only with the 6-inch barreled longslide target pistols and in the Tactical/Practical series with 5.3-inch barrels. These are respectively the Glock 17L and 34 in 9mm Luger and the G24 and G35 in .40 S&W. There is a long history of Glock factory literature adamantly stating that these trigger pulls are for competition, not duty or defensive carry. Every American police department that I know of which has adopted the G34 or G35 for issue has fielded it with a heavier trigger pull.
Measured at the toe of the trigger, the nominal 3.5-pound connector with standard trigger spring actually weighed three pounds, 3.7 ounces. Measured at the center of the trigger, however, it tripped at five pounds, 1.3 ounces.
Some Glock aficionados think the trick set-up is the 3.5-pound connector with the New York Trigger (NY-1) module replacing the standard S-shaped trigger spring. This gives a firm resistance from the beginning of the pull. The real, often unrecognized benefit of the NY Trigger is a smooth, easy pull that is generally estimated at a bit over five pounds. In fact, it measured six pounds 0.5 ounces at the toe of the trigger, and eight pounds even at the center. This system is reportedly standard with a Midwestern state police department that issues Glocks.

The Five-Pound Connection

The five-pound connector mated with the standard trigger spring is what comes out of the box when a private citizen buys most models of Glocks. It is said to have an average pull of 5.5 pounds. In measuring this combo on my G22, Dave got four pounds, 1.5 ounces when the gauge was hooked to the toe of the trigger, and six pounds on the nose when he attached it to the center of the trigger.
Then the threw in the NY-1 module, which is what I had in the gun to start with along with the nominally five-pound connector. It went six pounds, 1.1 ounces at the toe, seven pounds 1.5 ounces from the center. This combo is normally expected to bring pull weight up to eight pounds or so. However, I've shot this gnu a lot and worn it in well.

With the NY-2, or New York Plus module in place, which is said to deliver a pull of close to 12 pounds, we got eight pounds 1.1 ounces at the toe and 10 pounds even measuring from the center of the trigger. Finally, with the so-called "Miami trigger"--an eight-pound connector and the standard spring--the pull measured six pounds six ounces at the toe and 10 pounds even at the center.
The bottom line? As with all pistols, individual Glock pulls may weigh more or less than specified, or anywhere within the specified range. The pulls are indeed heavier at the center-where most of us actually put our finger-than at the tip. It was an interesting experiment, but I'll still keep the NY-1 module with five-pound connector in all the several Glocks I own for self-defense.

Here is a link to where I found this article:

So have you played with your Glock trigger? What have you found to be the hot set up for you?

Other than tirgger, sights are the only thing that I am inclinded to alter on a Glock. We can take up sights in another thread.

PS I went on line looking for somethng on how to ID Glock connectors and found this:

THE UNOFFICIAL GLOCK ARMORER’S MANUAL
Compiled by John Hisghman

Sorry, I tried to provide a link to it but it did not work. Just google search for the above and you should find a way to get to it. I found it by Google searching for "glock trigger connector identification" and found a link provided by Glockmeister.

The Unoffical guide not only has the connector ID info but a wold of other valuable Glock info including stuff on combat shooting.

EDIT: Try this link provided by Dave:

http://www.halfzware.com/wordpress/wp-content/uploads/2006/03/GlockUAM.doc

I have copied the info on CQB in the "Defensive Scenarios & Tactics" section of this forum in a thread called "gunfighting" - Awsome.

As always you educate and inform. My hat's off to you. You are an asset as important as the weapons we all carry. For without continuing our increase in knowkedge our mind becomes rust.

I had two Glocks, a 32 with the 8lb trigger and a 29 with the 5.5lb trigger. I had no problems with the 32, but with the 29 I would occasionally fire off a shot prematurely while recovering from a prior shot. Installed a 8lb upgrade in the 29 and my problem went away. Most of my other pistols have a fairly heavy trigger pull also which may explain why it works better for me.

Do you think your "premature discharges" were the gun or the way you were operating it?

I have never heard of a Glock doing that.

Any Glock certified aromors here?

My PSL "Dragunov" started firing on trigger reset about a 1,000 rounds after the install of a very lightly tuned Red Star trigger system. Brought it back to the gun smith that had installed the kit and he said that parts had worn (grove developed) and he fixed it. So I guess a defect can exist that can cause discharge dduring reset.

My primary EDC (Glock 19) has the NY#1 trigger spring, I like a little bit heavier pull.
