i have a g19 gen3 1.5yrs old about 600rds through it. i'm having some accuracy issues with it.

my first shot out of a cold barrel is always 1 ft low and my gun will not hold a group to save its life, i have a problem getting a 6 inch group at 5yds, this is with both target ammo, fed, cci, wwb, rem and premium self defense rounds, remgs, hornady, speergd, winpdx, i cannot get it to group with anything

i have had other people shoot it and the same thing happens, it is my ccw and i have no confidence with it whatsoever

what should I do, i'm seriously thinking about trading it in? did i get a lemon, will glock correct the problem? i dont have the money to invest hundreds of dollars into it

thanks for any help, Zack
 
If you didn't have problems before I would bet that a likely culprit could be the crowning of the muzzle. Maybe have the muzzle recrowned or get a new barrel put in. In my experience most firearms companies do not do warrenty work for accuracy unless a certain degree of accuracy had been promised.
 
Are you benching it? The glock is one of the hardest triggers to get used to. I shot 1911's all my life and recently switch to glock, took me a while but I can shoot a 4 inch group at 30 yds with my glock 23 now. Usually when you get groups like that it's trigger control, not the gun.
 
as i mentioned before, i have had other people shoot it to make sure it wasn't me, the 3 other people who shot it were 2 nra pistol instructors and my uncle who was a marine armorer for 20yrs

my friend and i both bought g19's the same day and i can shoot 3" groups at 15yds all day with his g19, so i think i have proven that it is not operator error

No, that doesn't sound like user error.

First thing I would do is contact Glock. What you're describing is far outside of normal or acceptable accuracy for Glocks or almost any other handgun. My G19 is very accurate, pretty much as accurate as I can shoot it. Most Glocks I've shot have also been quite accurate, within reasonable expectations of a service pistol (guesstimate ability of 3" groups at 25 yards).
 
Your front sight sounds like it may be the problem, after the first shot it is slipping back in the slot it sits in. But is still flopping around. take a look, Frome here that's what I see. Let me know if i am right, just field strip it and check the hex srew under the barrell. The sight may be sitting on the ledge on your first shot from being on a table or in a holster.
Boy if I'm right I will be happy for you
 
At 5 yards there is nothing mechanical that will make a 6" group. Not barrel crown, not barrel slop, nothing. At that distancea 2" barrel will make one raggedy hole,and I dare say that a 2" barrel with no rifling would do nearly as well.

It's you. Get with an instructor who shoots GLOCKs.

Until then, concentrate on a straight back to ya trigger press, keep your eyes on the sight. If you can't tell which way the sights go when the gun fires, we have solved your problem; you're blinking.

If you don't get it fixed, I'll dispose of the gun properly for you, and I'll waive my customary fee as you are a THR member...LOL

Is reading a dead art here on THR? Here's what the OP said before the post I'm quoting above:

I have to agree with a lot of folks here; it's not the pistol. I can appreciate your frustration with poor shots, or wanting to make sense out of some mechanical combination of perceived issues. But, it's not the gun, ammo, or a valid argument with only one or two others shooting the gun.

There are hundreds of thousands of G19s out there that all start off with a finger convinced that there is something wrong.
 
Maybe someone installed the NY1 police trigger. Cause it sounds like you've got policeman accuracy there. Better check to see if anyones dog is missing around your ranges area. :uhoh:


Check if sights are loose. Clean the barrel really well. Is the trigger too stiff and breaking weird? Check to make sure barrel crown isn't dented. Detail strip entire pistol. Check locking block, take down lever spring, trigger spring, barrel lugs, barrel/slide peening, etc. etc.
 
thanks for all the help guys, i'm going to totally strip the gun when i get home and take a closer look at it. FYI the gun was NIB from glock so it should have the std 5.5 trigger spring but i will check that also, i really appreciate all of your suggestions since i've been trying to figure this thing out for over a year now
 
After a year and a half you need to just call Glock. Send it back. Why continue to waste time and money.
 
If your friend has a G19 also then switch barrels with him and shoot both. That is going to isolate the barrel as the possible culprit or clear it as the possible problem. It its not that then do the same thing with the slides.
 
^^Great idea.

My glock 19 will do 3" groups at 25 yards on average. It sounds like a defect in the barrel. Contact glock and see if they'll help you out. There customer service is really good, so I bet they'll take care of you. If they don't try using an aftermarket barrel, they can be easily had for about $100. You'll loose at least that much trying to trade it in towards a different gun.

Has it had this problem from the start, or is it a recent development?
 
it has had the problem from the start, i bought it NIB from cabelas and tried to return it to them a week later to have them send it back to glock but they said it needed to be broken in before it would fine its groove, and now its a year later and i believe it actually shoots worst. i'm gonna swap barrels with my friends glock 19 and give that a try and i have been meticulous in my cleaning and oiling so that is not the issue

i would love 3" groups at 25yds, right now this gun shoots 3ft groups at that distance
 
I think it's probably one of:
-loose sights (maybe just loose enough to move under recoil but not when you hand push on them)
-barrel dimensions defective
-very loose slide to barrel fit
 
You have a great advantage in that your friend also has the same model. With your friend's permission, I would swap out the entire slide assembly with barrel, recoil spring, sights, everything, and try running it on your frame. This should tell you immediately whether or not there is a mechanical problem. If the problem follows the slide, you can narrow it down from there by swapping the barrel. If the problem remains with your frame, check to see if the locking block is loose... or if it looks different in any way from the other one.

Having two identical pistols to work with should make troubleshooting very simple.
 
I think it is (your), similar to flying, when it comes down to problems...Pilot error:)

Edit...

Glock will fix it if you send to them one way you pay, they do work and return no cost to you...

But you are bucking it, and need to understand true marksmanship imho...

Regards

Look for a local Glock Armorer. He can take a quick look at it and tell you if something is out o f whack. If it is, Glock will make it right or repair it for a nominal fee.

Interesting responses here. Maybe you could ask over at GlockTalk.com They may be less likely to wail on user error - maybe not.
 
thanks for all the info guys, gave glock a call and they said to send it back immediately so it will be in the mail tomorrow (on their dime)

as i have said before i have shot my friends g19 and have been able to shoot 4" groups at 25yds with it, so how come if it was me that is the problem that i can shoot 4" groups with his glock and then shoot 2ft groups with mine......just a little food for thought
 
If it isnt you, check for a cracked locking block...

I used my 19 at 21' to put 5 shots into the same hole last week at the range! at 75' I was hitting playing cards with consistency... I am an average shot.

2 years ago I couldnt even come close to hitting the 'X' at 21'. Its all about practice and range time...

Best of luck!
