    I bought the stormlake g32 barrel for my g23 first. So far its been flawless. It has just a little bit tighter chamber than stock. The only difference other than rifling imo is the stock barrel has a good smooth finish with rounded edges. I just bought a factory sig barrel and so far it has shot great also. I plan to cc the factory barrel and only shoot jacketed bullets in it. As for as Lw barrels I've never had a problem with the 40 and 45 barrels I've bought from them except for the shorter chambers which should not apply in 357sig.

    I use Glock barrels in both .40 and .357sig. The .357sig Glock barrels are supported very well.

    Is there a .40 barrel that is supported, and reliable as stock? Or is support at the expense of reliability in the .40?

    Although the question was posed to DKF, I figured I'd way in...

    The aftermarket bbls can be hit or miss, support and/or chamber dimensions can be a factor in reliability.

    Here's a vid that shoes a few different bbls and chamberings to compare. *Little bit of language.

    The .40 Glock barrels made within the last 10 years or so are supported pretty well and are reliable. Some of the aftermarket barrels do have slightly better support by not adding as much chamfer around the feed ramp and entrance of the chamber. There is usually some tradeoff.

    The .357sig and 9mm Glock barrels are better supported than the .40. I have not have any issues with the Glock barrels and they are quality piece so that is what I use. Whenever I pick up a G24 I will either pick up a Storm Lake, KKM or Barsto .357sig barrel for it because Glock doesn't make any 6" .357sig barrels for it. Wish they did.

    Using factory SAAMI spec rounds, there never was a problem. There has been continual refinement, but not resulting from rampant failure from spec rounds. Older barrels were quite adequate, but not as able to compensate for overcharged rounds or reloaded brass. I've owned and been issued .40 glocks since they came out, and despite heavy agency and personal shooting, never encountered or observed a problem.

    EXACTLY!!

    The problem was never so much the chamber support as with the ammo. The early Federal cases marked "FC" usually being the culprit. They have long since been withdrawn for the most part, except for a few residuals scattered sporadically in the hands of non LE. There is no such thing as 100% chamber support outside of a revolver as well.

    FWIW, I have a new Glock Gen 4 OEM .357 SIG barrel I play with in a Gen 4 G23 and it is superb. To be frank, it shoots just as good as my p229 in .357 SIG.

    Body armor is useful against common handgun cartridges, but nearly useless against hi-powered rifle rounds.

    Dumb question, and I'm 99% sure I know the answer, but just want to be sure before I buy...

    The G32/23 barrels are identical Gen3-Gen4, right? :dunno:

    No, they are not. Gen 4 barrels have a larger cutout for the dual RSA.
