Glock trigger differences

[PalmettoPrecision]

Lately, I have had a good bit of hands on experience with a multitude of different Glock handguns. I own two, a Gen 3 17 and a Gen 4 34, but have handled and shot my father's, friends, and handled close to all of the ones that are for sale at my work. All of them have differentiating triggers, even ones that are the same exact model. Some of them differ slightly, while others are either VERY heavy, or very smooth and much lighter. I have noticed this in both gen3 and gen4 models. I understand that connector differences can produce different trigger pulls, and have accounted for that in my observations. For instance, my g17 has a heavier trigger pull than new gen 3 guns at my work, even after 3000 rounds of "break in". My glock 34 gen 4 has a completely different feel in the break (with a dot connector) than a good friends glock 23 gen 4 which is much crisper and slightly lighter.

I am trying to figure out why... what internal parts are subject to differences in tolerances to produce such results?

Tolerances I would guess.

I have a G17, G19, and a G23. All of them have the exact same parts installed. I changed all the springs at the beginning of the year. The parts have roughly the same round count on them.

The G17 and G23 triggers feel about the same pull wise but the G19 is a little heavier. The G17 makes a "springy" sound when the trigger is pulled.

I have noticed the same thing.

The one thing that I changed on all my Glocks was to put DOT connectors in them.

between my glock 17,19,22 and 23, my 23 has the smoothest lightest pull even though i switched out all the components for identical ones. the 23 though has a slightly mushy pull while the full sized ones have a more pronounced break

I've owned or been issued literally dozens of Glocks over the years, and I will say that while Glocks are great for what they are, consistency is not the strong suit of the line. Trigger pulls, fitment, finish, and accuracy can and do vary wildly across various examples of the same model, even those whose serial numbers are close together...

Glock triggers are like Forrest Gump's box of chocolates if you get my drift.

FWIW, on my competition Gen 3 G34 I have spent at least a couple hundred bucks on parts, and numerous hours stoning the contact points on the trigger group. What I've ended up with is a pretty nice Glock trigger.

On the other hand, I recently got a gen 4 G17 that all I have done is drop a 3.5 connector in, and I honestly like the feel of that trigger better than the one I've spent hours and $$$ perfecting.

It's a crap shoot.

An LEO friend, who's also a Glock armorer, was kind enough to install a Glock 3.5 connector, that I was lucky enough to find and buy. I didn't want any other brand after market connectors.

With the 3.5 connector there's a much crisper feel than the stock trigger, which wasn't all that bad, but the new one is better.

I'm going to guess it's how rough the parts are.

Keep in mind that the Gen 3 and Gen 4 trigger bars are different (the hump).

Gen 3 with minus feels lighter, but creepy. Gen 4 with minus is slightly heavier, but had a nice crisp break.

Absolutely hated the Gen 4 trigger with dot connector combo. Never bothered playing with the dot connector along with a gen 3 trigger bar.

A 3.5 trigger connector and heavier (yes heavier) trigger spring can make the pull weight quite a bit lighter. I don't bother with the 25-cent procedure but I've heard it makes a bit of a difference for an out-of-the-box Glock. If a Glock has been shot a lot, the metal trigger parts that rub on each other are already naturally polished, in just the right spots.

It really is a crap shoot. One thing that makes a difference in how "crisp" the trigger feels is barrel/slide/frame fit. If you watch the rear of the slide where it meets the frame as you pull through the trigger, you'll see the rear of the slide dip down towards the frame before the trigger breaks. Drop in a match grade barrel (I use a Bar-Sto) and a lot of that is eliminated. If it's skanky out of the box, the .25 cent fluff & buff does help. As GunBugBit states, so does a lot of shooting and dry fire.
