    I have a Glock model 22, .40 S&W caliber, that I recently bought. I'm very satisfied with this pistol having gone through a handgun training course, and gaining more experience with it.
    I have read about installing an after market barrel for the Glock, such as a Jarvis or Barstow. I shoot only factory ammo in my pistol, and of course no lead bullets or reloads.
    I want to change to a supported barrel just to have that option.
    Which make of barrel is the best, and are there other brands of supported after market barrels just as good.
    Thanks for any advice.

    I see a lot of action shooting competitors with aftermarket barrels in Glocks. I don't remember the last time I saw a box stock Glock jam in competition with factory ammo, but I can't say the same for the guns with aftermarket barrels.

    I don't think the gain in case support in a Glock 40 barrel is worth enough to even bother. The likely reduction in reliability would also make it a concern.

    Unless I wanted a much more accurate gun and/or was going to shoot a lot of lead bullets I would not change the factory barrel. If I did want the utmost accuracy or lead bullet compatibility I would look at the Bar Sto hard fit barrel.

    I have in excess of 10K rounds through my G22, 99.95% reloaded ammo and EVERY round has been factory power or higher. It shoots accurately enough, is stone reliable, and hasn't had a bit of trouble.

    It is my opinion that the chamber support in the factory Glock 40 barrels is plenty good. It is my opinion that setback is responsible for nearly all if not every KB that you hear about.

    I can't say for certain of the Barsto barrels, but I can certify that the Jarvis barrels do not have a fully supported chamber. Sure, there is more case support than a factory barrel, but you're still going to have the unsightly case bulge.
