Hello,
I have been trying to fix the issue of my Glock 19 'Shotgunning' or having no group at all. Prior to this issue I was having very tight groups out to 15 yrds before the pattern began to open up. My Glock has shot about 1500-2000ish rounds through the gun. I do not know what to do in order to fix this issue and was thinking of taking the gun to a local smith to see what the problem could be. Ideas on a recoil spring or bad barrel (All seem to be in clean/working order)?
Thank you for any help/ideas.

Send it to me. I'll fix it. lol

Are you shooting lead?

It's normally the indian and not the arrow. Make sure you don't have too much finger in the trigger. Pull with just the pad of the finger not the first joint. Don't try and figure out where you are shooting right away. Checking the target for holes after each shot leads to improper followthrough and will not yield good groups.

try again with a Sandbag or Rest, to take you out of the equation...

You may have cracked something. Clean it real good, check the locking block, the frame rails, the slide at the ejection port, the barrel, the striker, etc. If everything is good, shoot it off a benchrest. Then report back.

Slide stop spring good? Change in ammo? Might be time for a new recoil spring? Was the gun detail stripped just before this started? Tried shooting it bench supported? Any changes whatsoever just before this started?

My Glock 30 "opened up" after the slide stop spring broke and the slide stop fell out before I noticed it. Otherwise, ammo differences accounts most changes.

Good luck.

Full, modified or improved? Sometimes it's a bad range day, sometimes a damaged part and sometimes a loose sight. We need details. How clean, what load, what distance, any alterations, experience level?

If there's no rhyme or reason to your spread (left-to-right, or up-and-down), then there's a chance it isn't you.

Take it to the range and shoot off a rest, sandbags, whatever... anything stable. Focus on pulling the trigger back very, very slowly, without moving the sights. Take a few dry fire practice shots. Then only take one shot, and don't let the trigger out until the gun stops moving. Give yourself another couple dry fires, and take another shot, aiming at the exact same point. Do it 10 times. Make sure to use your practice load...

If you are getting a lot of spread even with perfect conditions, then change ammo. If it still happens, call Glock, because it's likely a barrel issue (assuming nothing else is going on with the gun that is visible). If sights are off, they should still print a reasonable group, just shifted left/right/up/down.

If it is you, then don't sweat it... 15 yards is enough to exaggerate any flaw in your shot.

Thanks for all of the positive replys.

I really do not belive that the issue is with me because I have other semi-autos/revolvers and this issue is not present with any other firearms that I take to the range with me. Im not saying that I am perfect but the issue isint to much or to little trigger finger (right to left shots) or anticipation (diagonal misses) or a wrist issue (up and down). ...I think I got that right from my memory.:scrutiny:
I will look into the list of parts that have been mentioned above and double check them closely.

I will report back.

Do yourself a favor and shoot it off of a sandbag or some other type of rest.

I will shoot her off of a sandbag/rest.

I cleaned the gun and their was no noticable cracks or breaks at any location that I have found.

Planning on having a range day tomorrow.

Shotgunning tends to indicate that the shooter in blinking just prior to the shot breaking. Are you sure youre keeping your eyes open?

What ammunition was used when this was happening?

Has anything been done to the G19 by you before this started happening?

I reload my own ammo and have done no modifications to the Glock 19.

Is it possible that there is a carbon build up somewhere?

GrandLotus, have you been shooting cast lead reloads? Last time I was at a gunsmith, he was handing a man back his glock and sayin something to the effect that he fixed up this time, but next time he's gonna melt it... apparently glock rifling doesn't like high velocity cast lead.

Try the same drill with factory ammo.

Tell us you're not using lead or somebody's budget "copper washed" lead bullets.

Are you using the same canister of powder you've previously used for all the other reloads that didn't exhibit this accuracy issue? Changed your load? Your bullets? Primers?

You might also have a Glock armorer check the gun out. Sometimes an observed occurrence is a symptom of a problem, and not the actual (underlying) problem.

I feel sure the OP would have let us know if he was loading lead or copper-washed....wouldn't he???? :cool: Really sounds like a leaded barrel, if there are no cracks in the locking block or slide.

What kind of bullets are you loading?

Not to hijack your thread but, I am having the same problem I even shot from a rest sighted in properly and my shots are all over the place. Can shoot revolvers pretty good but the Glock I don't know.

Make sure the barrel is locking up all the way. If it's locking up tight and consistent, the main culprit would be either the ammo or a defective barrel.

At 15 yards the style of bullet isnt going to matter, nor will a bad barrel. Its you, man. That close, you are the only variable that has enough randomness to ause this sort of problem.

What would be the best way to see what I could be doing wrong if it is me?

I have little experience but was with a guy at the range who had a 9mm glock that was all over the target.
Changed ammo and it was very accurate.

Turns out he had reloaded with .355 diameter projectiles whereas .356 was very accurate.

I was suprised it made a such a dramatic difference, but I saw the groups at 25 yrd go from the WHOLE target down to a few inches (both shot from a sand bag)

just a thought.

It's not a "C" model, is it? I had one that cracked at the port. Keyholed 'em all over the place.

I also had some bad bullets that separated cores and jackets all hit the target at different places.

I also had some electroplated bullets that my gun(s) couldn't throw straight for nothing.

But if none of this applies, it well could be you.

Let some proven Glock shooters fire your weapon. If it shoots well for them, then it's your shooting that needs work not the gun. Then let them watch you shoot, and help you figure out what you're doing wrong.

I was raised on revolvers too, but Glocks truly do require a different touch. It took me close to a year of regular shooting with Glocks to get close to the accuracy I was achieving with my revolvers.

Send it to me!!! I'll gladly test it out for you.

Yep.
Was a carbon build up and now the glock functions like new. Completly broke down the firearm, cleaned it and then reassembled.
Sorry if I brought up a semi-dead topic.

Thanks.

I was wondering how it worked out. Glad you're back up and running.
