I have a glock 23 and have noticed that it shoots low. I have to cover whatever it is i'm shooting at with the front dot. Its got the original goal post sights on it. Is there a way to fix this?

Aim High?  

Hmm, I put the front dot on the target with all my Glocks. I think you may be doing it right.

Have you had someone else shoot the gun? Someone with Glock experience? I bet your G23 is sighted in just fine...

I believe you can get a shorter sight post from glock.

A shorter front sight or taller rear will raise your point of impact.  With factory regulated sights,a six o'clock hold should put hits on target, unless you're shooting at very close range.  Shoot from a rest to make sure you're not pulling the gun down.  It would be very unusual for an irregularity to develop here.

Thanks for the quick response everyone.

Possibility:
Most that shoot low are anticipating the recoil and kinda flench before they shoot.  One good way to check is to load a mag and somewhere in the mag throw a snap cap in the mix.  Start shooting and if you flench or dip the gun on the snap, it's you, if not then its the sight.

Look at the Right side of the rear sight.

It should be marked with one of the following:

––––––-
––––––-   two lines like an equal sign is very tall

 ––––
––––––––  short line above long line is the tall

–––––––– a long line is the normal sight and fairly standard

––––––––
  ––––     short line under a long ine is the short sight


These are also the four exact position heights of the Glock Adjustable Rear Sight.

The plastic sights are a couple of dollars and easily changed if you can borrow a  Glock Sight Tool.    Once changed and windage zeroeed, they never change.

As a practical matter, almost all M23s are sighted about 3-4" above the point of aim at 25 yards.  If you are shooting low, consider that it might be a consistent trigger yank.  I personally and me have never seen a Glock shoot low and absolutely not a M23.  The only way an unmessed with factory standard gun would be low is by shooting 85-90 grain 9mm ammo in something like a M19.  The problem with them is that they actually have about a 75 yard zero with standard ammo for the caliber and always shoot high at 25 and 50 yards unless you yank them down with a poor trigger pull.

Which is why I have a Glock tool and put the correct sight in for a point of aim/point of impact at 25 yards setting.

I always put the dot on target with my 23. If I recall, Glock does not set up it's sights for 6 o'clock.

If you're putting the front dot ON the target, and hitting it, it sounds as it should be.

That's what I've always done.  No "6 o'clock hold" here, I line them up and put them ON the target.  

No different than any other pistol.

but seriously, might not be a bad idea
