    New glock 23 accuracy issues


    Hi all,
    So after trying several different handguns at the local shooting range I was very impressed with glocks accuracy. Yesterday I went and bought a new 4th generation glock 23 and took it to the range today. I shot about 60 rounds through it and found it wasn't nearly(still an understatement) as accurate or precise(generally low and to the right, but really just everywhere) as the beaten up range glock I had previously shot, also after one range session there was a significant amount of wear, see attached image, on the barrel( leading, etc.). I dont believe its the sights because the group wasn't tight, nor do I believe it was me because in my previous glock encounter I obliterated the bulls eye at a longer distance and generally think of myself as an above average shooter even competing at small bore rifle several years ago. Could it be a defective barrel or some other issue?

    YOUR EYEBALLS ARE CROOKED! nah j/k. Thats a bad picture but if there is significant barrell wear then you definitely have a problem. Also, were you shooting the same ammo as before? What kind?

    What kind of ammunition are you using? It looks like you're using lead bullets and they're gumming up the barrel... If you are shooting lead, you need to stop and clean out the barrel before you shoot any more...

    It's hard to tell from your picture, but it looks like there are clumps of lead in the barrel... OEM Glock barrels don't like lead...

    Make sure you clean that barrel before you shoot it again!!!

    You should not shoot unjacketed lead in a Glock. Jacketed or plated bullets only. If you want to shoot unjacketed lead, use an aftermarket barrel that has conventional rifling.

    Besides that, the range gun you shot probably had a well worn in trigger. It'll take a few hundred trigger pulls for your trigger to smooth out, plus because yours is a Gen4 it'll naturally have a heavier trigger pull due to the bump on the arm of the trigger bar that engages the firing pin safety and the fact that the angle at which the connector sits in the trigger housing is different by 5 degrees. Those two factors can add another 1lbs to the trigger pull.

    Try using the trigger reset. Pull the trigger, hold the trigger to the rear while the shot fires, then once the next round is chambered let the trigger out until you feel a click in the trigger. Press the trigger again to fire. Accuracy is much easier to accomplish without all the slack to take up in the trigger for each shot.

    Also if you haven't done it already, lubricate the interface between the connector and trigger bar with a small drop of oil. At 3:25 into the following video that spot is shown: http://www.youtube.com/watch?v=pGobEpUO3Uc

    I will second voyager4520 and say it is probably a trigger issue. When I got my brand new gen4 G19 I too had accuracy issues, and it had to do with the stock connector/heavier trigger pull ocmared to a stock gen3. After changing to a Ghost 3.5 connector the difference was night and day. The clean break and lighter trigger pull did it for me. I did not touch the dimple as it was not necessary for me, just the connector worked fine.
