    Factory fmj's chamber just fine. However, loading hornady 124's I had to seat them to 1.090 to get them plunk test. Anything longer get jammed into the lands. My G 34 loads have an oal of 1.115. Should I be concerned ? Maybe contact glock ?
    Thanks

    Nope, pretty common with a lot of guns & certain bullets. Why OAL is always gun & bullet specific. The truncated cone or XTP type is always going to load shorter. Just be aware you can not just shorten the OAL without dropping the powder charge. Though 0.025" isn't moving the pressure needle much, unless you are loading max loads.

    Sounds like a CZ,my shadow has a very short throat which after working with it I have found it to be a + IMO. I don't run hot loads in it anyway and it saves me a couple tens of powder every time I pull the trigger lol.

    The early Glock "Markman" barrels came with extremely short throats. It appears in recent runs they have cut the throats a little deeper, but still shorter than traditional Glock thorats (very generous).

    TC profile bullets like Hornaday XTP, PD JHP, etc. are particularly problematic as they have a long bearing surface.

    As Fred noted, develop your loads for the barrel you are loading for and you will be fine.

    I just successfully plunked some 147 gr Federal HST's with an OAL of 1.122 into both of my Glock 19 Gen 5's. Both guns are newer production with the beveled frame.

    See if you can find any factory ammo that won't chamber because of the short throat and then contact Glock and tell them to send you a barrel that will work with all ammo.

    Otherwise if you contact Glock and tell them that you're having problems with your reloads they'll tell you that you aren't supposed to be using reloads in your Glock. But Glock needs to know that while a short throat may give slightly better accuracy, it has no place in a duty gun.

    Yesterday I bought a box of factory loads with the 124 XTP'S. The average coal of 6 was 1.065. So, I haven't been seating them deep enough. My fault !

    You load a given bullet profile to a specific OAL, that's all. I have run from 1.060 for RN to 1.175 for JHPs.

    Exactly. OAL is gun & bullet specific, always.

    What ever OAL it takes to plunk test. Remember though as OAL goes down pressure goes up so drop your charge weight .2 grains or so, depending on the powder, and check in on the chrono. If you don't shoot competition, no need to chrono.

    currently running these for USPSA Minor floor, left 124 Black and Blue over 3.4 grs of TG at 1.100" and 124 Bayou over 4.6 grs BE-86 at 1.100" Both clock about 1,050 fps out of a OEM G17.
