    Don't know which drives me crazier, this kind of advice ??..... or Hillary voters?? :brickwall:

    Do I understand that this 50 something year old guy should simply try to retrain a lifetime of how he has always held and fired his guns accurately, and how he would automatically fire his guns in a defense situation accurately (and automatically)........ just to work around problems with one troublesome Glock gun?

    Is that the recommendation? I might as well be hearing; "Sir, you can change your handrwiting if you will just practice holding your pen different."

    I shot my second best PPC score with my Glock 20. The only modification is a minus connector. Hours of tack driving fun with my Glocks new and old.

    Thanks for replying everyone. I have sent the gun to glock for them to check. I was able to put it in a vise and lock it down and it was still off 5-6 inches left at 17-20 yards. For a hunting gun this is not acceptable and that's what Glock says this gun is for. I'll update y'all in couple weeks. They claim turn around is about 14 days. Thanks everyone

    Good luck on the warranty work. Yes, please do post a follow-up range report.

    As far as what Glock thinks the G40's primary use is, ... they certainly built improved hunting capability into the set up with MOS-ready platform. Still, I've found mine to be super-accurate with a set of fixed Trijicon night sights, the front sight having a green dot to contrast with the orange rear dots.

    For me, the G40's ideal use is as a rough country/backwoods/boonies gun. Durable, accurate, high-capacity, and it certainly carries easier than any one of the all-steel mega-magnum wheelguns. With the G40 secured in a proper center-chest holster, your hands are free while hiking, doing camp chores, or fishing off a river bank for salmon out in the Alaskan bush.

    Amen I could not agree more on the use of G40 and chest holsters

    I agree, don't think you'll need to move therear sight very far, hate to say it but you could alter the notch in the rear or the front.

    Food for thought, if you are right handed try pushing with your left thumb, weak hand, on the frame and steer the pistol if you will. Slight pressure to the right, I've done this before with success.

    OP has said the pistol is going back to Glock.

    Yeah, let Glock correct the issue under warranty. It might be that just swapping in a new barrel will correct POI.

    I've shot any number of different Glocks over the years, and I've never encountered a POA/POI issue that's as bad as what the OP relates in this thread.

    I haven't either. It will be interesting to see what Glock does.

    6"@17 yards on gun with a 8.19" between sights. We could do the math on that but I don't think you'd be drifting the rear sight to right very far to move that group right 6 inches at 17 yards...
    Have you contacted Glock?

    I think there are manufacturing variations in the barrel that might explain what you are experiencing. I own the the Glock29 10mm. I had it milled and mounted a red dot sight on it as you can see in my avatar. I discovered that I was unable to zero my red dot in with the stock barrel, because my groups were too big. I replaced the stock barrel with KKM threaded barrel. This caused my grouping to tighten up considerably and I was able zero the red dot.

    Later on a lark, I put a 6.02 inch lone wolf barrel in it just so I could simulate the Glock40. I discovered that I had to re-zero my red dot to accommodate the LW six inch barrel. I then discovered that the groups were even tighter and it was easier to control the recoil "flip". I understand why people like this as a hunting weapon. Of course the velocity of my bullets increased and the trajectory was very flat. 10mm are great weapons. The only problem I had with the six inch barrel was that it poked me when I carried as my CCW.

    I went through pretty much the same thing with a new G17. Ended up shipping to Glock @ $200+ they did a ton of stuff to it but now it shoot reasonably well as long as I use heavier bullets. As for the 10mm I've had a G20 since 93, and it definitely likes heavier loads as in 180 and 200 grain types. Hope things work out for you.

    Well everyone I got my gun back from Glock yesterday. Talk about a fast turn around. I have nothing to say but positives about Glock. The serial number is the same but everything else looks new. It came back with the butt plug in a zip lock baggie, the gun was very dry which is not how it was sent, and there is no residue anywhere-slide, barrel or trigger mech. The paper work only says service. Does have a four shot target that states 15 yards with all 4 shots in bullseye. I've only shot it 5 times (it's just too hot in Alabama now) but it hits where it's pointed now. Thank you Glock. One more thing guys, the sights are centered on side. No changes to sights to fix an issue. Thanks to everyone. I highly recommend Glock.

    That's great that you got it back so quick and it works properly. I sure wish companies would state what was done for warranty work, but in the end results are what matter.

    Yeah, great to hear! :cool: But before you start moving the rear sight off factory center, shoot it for at least 300-rds with full-power 10mm ammo (factory or handloads) to be sure that any questionable POA/POI hits aren't a shooter-induced issue.

    Yee gads! 300-rds with full-power 10mm ammo will cost more than the cost of sending it out for repair! I would be satisfied if I just got a dozen round on target.
