In an effort to improve accuracy I am contemplating a barrel (KKM, Lone Wolf, Zev etc) or a trigger (Zev or Agency Arms etc.) for my G-19. I have been working on my grip and trigger control for some time now and while I have not mastered either I would like to know which would do the most in improving my accuracy?
Thanks in advance.

Without question a better trigger will yield greater benefits in accuracy. I recommend the connector package from Taran Tactical

Assuming the ability to see the sights, Trigger Management is always the ultimate factor in shooting accurately
 
I second that. Learn to use your tools, better hardware won't help bad technique.

I'd been golfing for a few years with a cheap set of blades ($35) I got from the local pro shop, when I went back for custom set of clubs. The pro watched my swing and REFUSED to sell me a custom set, saying it was a waste of money. He put on new grips and gave me a few informal sessions on my swing instead. My game improved and I still have those same clubs.
 
I'd be surprised if a better trigger helps you shoot much more accurately when shooting slow. I'd be surprised if a better barrel helps shoot much more accurately when shooting fast. Neither will help if you don't have good fundamentals to begin with. But, at least the trigger is more cost effective.
 
OP: practice trigger control and experiment with different ammo first. There really isn't any shortcut.

Trigger for sure. A good crisp lightweight single action trigger with little to no creep or pretravel that you..........just can't have in a glock. :/

but in all seriousness, I could never shoot a glock very well. I just wasn't very good with my trigger control or grip. I tried the polishing, the 3.5lb connector, the lone wolf barrel, fiber sights, I just couldn't make it work for me. I couldn't shoot a 45 1911 either. I was too flinchy, even when loaded light after thousands and thousands of rounds. So I got a single action cz pattern clone. I shoot much better now.
 
For Glocks, the order of investment, ranked by benefit is as follows:

0) Training by qualified professional (made this naught for obvious reasons)

1) Ammo for practice

2) Trigger enhancement

3) Sight improvement

4) Barrel replacement

And noting here, there is a long, long displacement from 0 to 4 on this list.
 
********MORE INFO*********
Thanks all for the helpful information.
A little more about me. It probably would have been helpful to included this in the OP. I have been shooting as long as I can remember. Seriously shooting(once a week) for the past 3 years. I dry fire multiple times a week. I'm 62 so my eyes are not what they use to be, but I got a pair of prescription shooting glasses and it helped. I love my Glock but we all know their triggers are not great. A self diagnoses and info from other good shooters indicates a trigger control issue so I have worked on that diligently and it has gotten some better. To my untrained, unprofessional mind it seems to make sense that a smoother, crisper trigger with less takeup and a little lighter break would reduce barrel deviation especially out at 25 yards. Am I all wet on this?
Thanks, SCD

I think that's exactly right. Certainly it helped me. A new trigger kit from Lone Wolf or similar costs very little, is easy to install, and need not wait on any other purchases. Listing approaches in order of importance doesn't mean one has to do them in that order with each step waiting on the previous ones. There's no harm in entering training and expending ammunition with a better trigger in the gun.
 
A better trigger definitely helps. It's not just the pull weight, the shape of the trigger helps a lot too. Stock glock triggers have the tapered serrated shape that isn't conducive to good trigger pull. I have the zev adjustable fulcrum in my 35 and having reduced trigger reach and travel as well as flat surface made more difference than a lighter pull weight. I think any of the flat replacement triggers makes a big difference.
However, do not underestimate the grip factor. It took me a long time before I figured out the best hand positioning and support hand pressure. I had to try different grip positions before I found the way that would allow me to get a good straight back pull on the trigger.
Do you have a gen4? If so you might want to try different grip back straps. I assumed with my short fingers that I would shoot best with no blackstrap but I found that the smaller beavertail strap actually gives me better finger placement on the trigger.
If you have a gen 3 you might want to consider getting a gen 4 or a frame modification to fit your hand better. Rougher texture helps too.
All of these should be considered before barrel change. There is no accuracy advantage to aftermarket barrels. There are other reasons to get one, but accuracy isn't it.

Not all wet.

A crisp single action trigger is a crutch. If your technique is perfect, any "reasonable" trigger will let you shoot fine groups. The less awesome your technique the more an awesome trigger helps you mask the problems.

Ask a DA revolver shooter about needing a perfect glass-rod break or how bad a Glock trigger is and they'll chuckle.***

But none of us have a perfect technique, and most of us use an improved, good-as-it-gets trigger to limp our imperfect technique into respectable scores. :)



***-- I've sometimes answered this question with "a revolver.". Get a good da wheelgun and spend a year getting good with it. When you switch back your Glock scores will go through the roof!

I've spent the last year getting reacquainted with shooting a revolver in competition and it really did help with managing the trigger of a borrowed Glock at a GSSF match I worked

But I'm lucky, I have a Gen2 G19. Picking up a Gen3 G19/G17/G34 required changing the connector...hitting the "wall" just before letoff was a major distraction

While this arguably a true statement, I'm not surprised that even the most competent and proficient of shooters don't dally with crappy triggers, just to showcase their awesome technique.
 
No. Of course they do what they can to push for the best score possible by stacking a good trigger on top of great technique.

Not because they wouldnt beat most of us on technique alone, but because the other tip top of the heap guys have the best toys, too!
