    A little background, I've had this 26 about 3 mo. now about 900+ rds fired. I've put a stainless RSA, extended slide release, extended slide lock and a slide cover plate on it.
    Last 2 trips to the range resulted in multiple misfires and when unspent round is ejected I noticed the primer was hit off center. This happened afte 3 mags shot flawlessly and continued until I stopped trying.
    I would appreciate any help from the GT crowd, thanks.

    Check and make sure the firing pin itself isn't damaged. As in another thread their have apparently been a few problems with some of the firig pins in the newer Glocks.

    Same kind of ammunition both range trips or has this happened with different ammunition?

    Put the original slide cover plate back on and see if that is it.

    An off-center primer strike probably means the gun is not going fully into battery. Check before each shot to see if the slide is fully forward. If that is the issue, put the original RSA back in. And make sure the slide lock isn't in backwards; the groove at the top should face the rear.

    Return the G26 to stock and test.
    If does not work, return to Glock.

    Thanks for all the input, heading to the range today to troubleshoot with your suggestions.

    The trouble is with the aftermarket slide lock. This is keeping the barrel from going fully into battery.

    At the range with the after market RSA, ext. slide lock and ext. slide release the 1st mag shot fine, the 2nd mag had 2 off center hits.
    I changed the RSA back to OEM and shot 70 more rds no off center hits but on the last mag I had 1 rd that didn't load.

    I would try it with everything stock, and see if it happens. If it's fine, put the aftermarket parts back one at a time, and test individually.

    Have you cleaned the striker channel? Mine will start to get a noticeable amount of brass and carbon in there at around 1k rounds.

    As a general aid these diagnoses, when a trip to the range is not practical:

    1 - Keep some fired casings. You could thoroughly cover the fired primer face with sharpie, chamber the empty casing with the existing firing pin marked clocked horizontal, and see where the firing pin is striking after performing a possible fix

    2 - Get a $25 inertial bullet puller. When you can't go to the range, use the bullet puller. Put the slug on display, flush the powder, and you'll have an empty primed case. Follow all safety guidelines, select a safe backstop, and you can fire just the primer, no powder or projectile. A minor "bang", and you'll have another primer mark to examine.

    Folks who can shoot off the back porch don't need these techniques, but it's saved me a 40 minute round trip many times.
     
  18. Ok you really need to go in smaller increments here. If I were you I would do the following. I would take tools and so forth to the range as well as a few hundred rounds if you have them. Prior to the trip I would return the gun to its stock factory configuration.

    Run 100 rounds completely factory and see how she runs.

    After the gun is preforming factory put these parts back in one at a time if they are what you want (obviously or you wouldn't have bought them.)

    Swap the rsa and get 100 trouble free rounds if not that is your problem
    next slide release and see where you are
    next extended slide lock
    finally slide cover plate.

    One of those 4 parts could be causing your issues or any combination of the 4. The only way to know for sure is to test them independently.

    Regards, GMB
