Glock shooting high

[Caddis]

Picked up a couple of new Glocks and my 30 is shooting 3-4" high at 15 yards using factory sights. Tried different ammo and same thing. Do I buy a taller front sight or lower rear sight?

Don't want to spend a lot on money on upgraded sights.

Thanks

Have you let anyone else shoot it to see if they get the same results?

Are you aiming with the top of sight or center dot?

What size group are you getting at 15 yards?

And yes- has anyone else shot your gun? Do they hit in the same spot?

Only me shooting. Aiming with front top flush within rear and target on top. Have two other new Glocks and they are dead on with my eyeballs. Groups are 2-3 inches benched but shooting new recipe reloads so not worried about grouping yet and don't think it's an ammo issue because I used two different loads with the same results.

Thanks for the input fellows.

My experience with the stock "bucket" glock sights is that most people tend to shoot high because the eye naturally centers the front sight dot in the rear sight bracket. However when you look close in order for the sight picture to be level the bottom 1/3 of the front sight dot is actually not visible. Everybody is different and prefers different setups, but if you want to depend on your accuracy in a real world situation I would start training with a level sight picture ignoring the dot or get different sights. I prefer heinie straight eight

Shoot a lighter faster load.

Lighter bullet.

That's really weird. If your target is on top, you should be shooting low, not high. They are combat sights, and usually you have to cover the target. Try that, and see if it helps... but it may possibly just be you?

I'm an old LEO and have shot and and
reloading for a while and I know everyone's eyes see things differently. It's definitely the gun since I have two other new Glocks and a bunch of pistols including my duty weapon with no issues. My original question was whether to change the front sight to a .200 tall (original is .165) for $50 (upgraded colored) or buy a new barrel for $100. Changing the rear sight seems difficult because I don't know what the original height is.

I believe you can find the formula for the sight hight correction on Dawson Precesion's website. They also sell a tall temp front sight that is designed to be able to easily be filed down to fit your poa / poi / load.

Good luck
