Let me say before I tell my story that most of my pistols and revolvers are S&W. I bought this new Glock Gen5 G34 MOS. Right out of the box it shoot 3" left at only 10 yards off of sand bags. I can shoot and this wasn't caused by my shooting. Even adjusting the sight to the right the adjustable sight had to be drifted to hang off the slide. This was very bad. Makes for a strange sight picture. So I called Glock, they probably heard crazy callers like me before but they were polite. Sent it in to them for evaluation. They received it Monday and I had it back Thursday, wow. In the box was a letter and test target. 1" group at 15 yards on the bulls eye. The letter stated that they replaced the slide stop, ejector and firing pin safety. Does this make sense to any of you? I am pleased but puzzled.

Everyone holds a pistol the way they hold it. From a machine rest, consistent results can be obtained. Handheld, results will often vary a bit. The folks at Glock have a well earned reputation for customer service. The parts replaced may possibly have had some sort of blemish in the finish. Take your pistol, get some ammo and head for the range! Sincerely. bruce.

The list of parts replaced should have no impact on where your rounds strike home. Did you inquire further?

If the slide stop was damaged or tweaked, couldn't that affect the alignment of the barrel with the slide?

If it is shooting left. Move the front sight to left(causes impact to move to the right) or block front sights pinned in one place?

Have someone else shoot it after or before you do. Many times this is caused by our grip or some other function of our own doings. If Glock is hitting the bullseye from a rest I’m sure the gun is fine.

One thing often overlooked is the position of the sun. If the sun is to your left it will illuminate the left of your front sight and you will aim left to compensate.

One day, while visiting the local indoor range, an “older gentleman” (about my age) came from the range with his new Glock 22 in his hand and protested to the salesman that the gun consistently shot about 3 inches left at 35 feet. The salesman, a middle-aged fellow and something of a plastic pistol hack, shrugged and observed, “Its normal for you old revolver guys to shoot left with a Glock!” We both knew he meant no harm, but to ease my own mind I asked the fellow if I might shoot the gun, and sure enough, I too was about 3 inches left. And I was being VERY careful. There may be something to his observation.

It clearly isn't the pistol if it shot perfectly for someone else. Perhaps there is a technique issue here?

FWIW Joe, I was wondering the same thing. I've read hundreds of your posts, and this is the first time I've seen an explanation as to why you use all caps - which in the internet world is considered yelling.

Don't take offense at the question. People who don't know the reason will always wonder. A simple statement like "I can't read what I'm typing unless it is all caps" should be more than enough.

And thank you for your service.

I don't know about your Glock, but I have a French MAB 22lr that shoots about a foot left and a foot low at 12 yards. I've tried correcting it, but like you I end up with the sights drifted so far to the right they're hanging off the slide. The height issue I can only correct with sight alignment. The worst part is that it has an odd dovetail size so getting a taller sight is problematic as well.
Sucks when a gun won't aim and shoot right - very frustrating.
And it doesn't sound like anything they did should help with the problem, but I'm interested to hear how it shoots now once you give it a try. Please be sure to let us know.

It has happened to me shooting old Mausers with the barleycorn front sight in bright, low-angled sun.

To the OP, you didn't mention if this is your first Glock? As I see it there are the following factors to consider, sight alignment, grip, trigger control and the pistol itself. Since most of the factors are related to the shooter then as previously suggested, ask one or better yet, several others shooters to give it a try.

If it doesn't shoot left for every other shooter than its not the gun.

From your post it appears that you got it back? Correct? Have you fired it? If not why not? You do not know if what they did made a difference. I agree that I would not believe changing the parts you listed causing an improvement in POI. As others have said shoot it, have some one else shoot it. It does not make sense to me , I am not a gunsmith, armorer, but if it hits to POA, that is what you want. You could always call them and ask why those changes would matter. Be Safe,

I AGREE THAT SHOOTING POI TO POA IS THE MOST IMPORTANT THING.....

I KNOW NOTHING ABOUT THE WORKINGS OF A GLOCK, BUT THE BALL IS IN THE OP'S COURT, IF HE WOULD LIKE AN EXPLANATION FROM THE FACTORY....

THERE IS ALSO MORE THAN ONE GLOCK FORUM, WHERE THIS QUESTION COULD BE PUT FORTH....

You know it’s now shooting straight from the factory. If you still have the same problem, just spend some good practice time getting to know that Glock trigger.

In my experience, stock Glock triggers need to be “learned” in order to avoid the low-left POA issue (for right-handed shooters) that you describe. Some guys get offended by the notion that it may ‘be them,’ but it very well may ‘be you’.

The advice to give it to an experienced/competent Glock shooter to try is great advice and will show you first hand what is going on, or not going on with that pistol. That’s what I did with my first Glock when I couldn’t believe it could ‘be me.’ Yup, the guy punched out a center mass, ragged hole with that darn Glock that was shooting low left...

I practiced, a lot, and I got good with the Glock trigger. Don’t misunderstand, I’m a very good shot, with many types of guns, and a lot of experience. It was different with the Glock. Look at all the aftermarket trigger solutions for Glock. Those are for guys that just don’t want to learn the trigger. Always an option. I like to keep my defensive guns stock.

This is just my opinion, no offense, and of course, it’s probably ‘not you...’. .

This is a fairly common occurrence with a new Glock shooter. If you go to the glock forum you'll see numerous threads where someone just bought a Glock for the first time and complains it shoots left or low left for right hand shooters. Very typical. The Glock trigger is not a target trigger for sure. It's long, spongy, and not like most other firearms.
When going to a Glock remember your shooting fundamentals. Concentrate on sight alignment and trigger pull. Use a bit more finger on the trigger.
One thing about the Glock trigger. After getting the basics down on a Glock trigger you'll be a better shooter. A Glock trigger makes you work on the basics and doesn't let you get sloppy.

Unfortunately he does not know it is "shooting straight". He received a target from Glock, that does not mean it was his gun. About 1994 I purchased a new 629, it would not hit a 3' X 4' target backer at 25 yards. I had a significant amount of practice with my 29, so technique was not the problem. When it was first sent to S&W they moved the sights back to a central position and called it good. I sent it back and they replaced barrel, trigger,hammer, sights, till they found out the frame was drilled a few ten thousandths to one side, they replaced the frame, built the gun, it shoots 1 big hole at 25 yards. So he needs to shoot it to see if anything changed. I totally agree that the Glock trigger must be learned and perfect practice, makes perfect. But a target from the company does not mean anything.
Be Safe,

Thanks to all of you for your interest in my G34. Lets see if I can answer a few of the questions. This is not my first Glock. I competed in the 90's with a G22. Since then I purchased another G22 Gen4, G19, G20, G21, G17, G36, G38 and this G34. All of them shot to POA. This G34 did not. I have a range at my house and within 30 minutes of getting the pistol back from Glock I was shooting it two handed standing up at paper. It now shoots to POA! like most of you I can't understand how changing those parts made a difference with one exception. The ejector is part of the rear "block" that includes the frame rails that positions the rear of the slide. But that would move the rear sight along with the slide. I don't have a clue but it works. Think I will shoot my S&W Gunsite 45 tomorrow.

Thanks for the update. Glad they got it straightened out for you!

Thank You for the update. Glad that it is working well. Be Safe,
