Help with accurizing a Glock 19

Accurizing Glock 19s
Taking my time at just 25 feet, offhand, my 11 year old STI 1911 9mm will put 10 rounds touching.
The best I can do with Glock 19s are sloppy groups of 3 or 3 ½ inches +.

The internals are a mix of favored parts. The trigger take up is clean, the break is light as well as the reset crisp. Sights are Trijicon HDs. All are OEM polished Gen 3 factory triggers and the barrels are factory. I tried a KKM barrel, there was no clear improvement. Spoke to KKM and they told me I would only see tighter groups with high end ammo. I shoot generally inexpensive 124 Arguillo or S&B.
I understand a Glock is not made for bullseye shooting but I should be able to do better.

All guns are Gen 4. 2nd hand I am told that Gen 5s are more accurate, but I am invested in the 4 series and like the finger grooves.
Looking for general suggestions specific to the Glocks that I can try out.
thx

Boy, It's not really a target pistol.

I've always seen Glocks as accurate enough though.

Good luck on your endeavor.

25 feet is nothing. To conduct meaningful testing, shoot at 25yds on a small target like a B8.
Most service autos are capable of a ~1" group at 25 feet.
Your ammo is capable of that too, but better ammo will improve it.
HD sights are a pretty coarse sight picture. Swapping out for a set with finer edges and narrower front blades may help.
The short, light trigger of your 1911 requires less effort and ability. Dedicated bullseye drills, ball and dummy, etc with the G19 will improve you.
Whether or not you like the finger grooves, the gen5 GMB barrel is better, narrowing the gap between OEM and the aftermarket.

So, ammo, sights, practice. Maybe a barrel, but probably not.

Here is the best way to accurize your Glock:

Shoot it. Shoot it some more. When you think you’ve shot it enough, shoot it some more.

It isn’t that the Glock isn’t accurate enough, it’s that you suck at shooting it. That isn’t surprising at all in that you’re coming off a 9mm 1911. The single-action 1911 trigger is exceptionally easy to shoot and masks many of your fundamentals errors.

I love to spend money on guns.

I love to think about spending money on guns that are high dollar items that I believe I will shoot better because of "insert X feature here".

The reality is that ammo, dry fire and time behind the gun is the only thing that is going to increase my performance.

As I said earlier, mechanically, the gun is more capable than you are, than most people are.

Im surprised no one has said this but years ago people loved to reference a popular saying "fix the software, its not a hardware issue". Im bringing it back.

Ive seen you shoot, you're not a layman. Put the time into the gun and you will see the reward. You cant rush it.

The trick to a Glock is treating the trigger like a shorter double action and not a 1911.

Also, lots of dry fire, and some with a penny set on the front sight.

I think that's a really good tip, and a very overlooked step.

I feel that I "stage" Glock triggers even more than DA/SA guns.

I agree. I shoot both Glocks and 1911s and have to press the trigger differently when switching between the two weapons. I manipulate the Glock trigger like a revolver when shooting and have had success with the technique. Decent groups at 100 meters are achievable with the Glock 19 and decent ammunition.

Dry fire drills are a great way to improve trigger control skills. I highly recommend dime drills to students when teaching a basic pistol skills course.

Kkm barrel and american eagle or geco ammo posts 2-3” 10 shot groups for me at 25yds... when I am on my game, and its repeatable.

In my experience, if you slack on dry fire, you wont produce good groups. Dry fire daily.

Unless you got an extremely bad gun, I would think its a training issue. Id try to find someone who can shoot glocks well try it to validate the gun.

Fwiw, 25yds: my gen4 is a 3-4” gun with stock barrel
2-3” with kKm
Gen5 is right around 3”

I only shoot offhand.
