Glock 30 hits 3" low of POA

Adirondack1 · March 01, 2011, 18:16

anyone else have this problems.

AndyC · March 01, 2011, 20:07

Only if I flinch.

Has a known good shooter tried your pistol?

**xtremerange** · March 01, 2011, 21:23

At what distance to target? If you are shooting 50 yards, then that would be about normal for 45 ACP if the zero was at 25 yards.

I have the same problem but I'm afraid its not the pistol.

**gunplumber** · March 02, 2011, 09:26

what rear sight do you have?

It is possible your gun came with a +1 or +2 rear sight, and then it was replaced with a night sight or something, not taking into consideration the height difference.

Stock Glock white dot front white outline U rears and I'm talking 20 feet , and yes I'm an accomplished shooter with a 1911 this is my first Glock

not saying that it 'is' the shooter but I have seen shooters have trouble before when shooting the Glock for the first time at several different shooting ranges, hell even I had trouble myself with a Model 23.

The shooters wheel does help refresh even the most experienced shooters.

I would also get the calipers out and verify the sight heights if there are no discernable markings on them.

There are 5 different heights of "stock" rear sights

You might also check the ammo. I have found that the Tula .45 ammo is REALLY weak. As in, it drops about 6" from POA at 15 yards. If I stagger the magazine Tula/Winchester/Tula/Winchester the target looks like I was aiming at two different parts of the target. I have half of the shots in a group around the x/10-ring and the other half grouped 6" low at six o'clock.

Just something to consider.

An how do I go about measuring said sights so that you know exactly what I have Mark?

Front sight should be fairly simple, however the rear, do I measure from the dovetail cut or the top of the slide surface?

0.4mm increments.

Adirondack1 · March 07, 2011, 18:14

The rear sight I have is second in from the left.

Small line over larger line.

**gunplumber** · March 07, 2011, 20:05

most glock 20/21 come with the +1 sight. The 9mms with the 0. Maybe the +2 will help somewhat.

Or you could get an adjustable rear.

I hate the stock Glock sights and always swap them out for some aftermarket ones, so I have never had this problem. I used to have a 30 though and with trijicon night sights found it to be extremely accurate -- by far the most accurate glock I have ever shot, so it has to be something like gunplumber is saying.

Adirondack, is this a factory new pistol or just new-to-you?
