    Will it be ok for me to use Gold Dot .123gr +P rounds as Concealed Carry rounds for a Glock 19? I'd like to have the +P round, but I don't want to ruin the weapon.

    I think you are not supposed to fire lead bullets in Glocks regardless of pressure though...I bought a non Glock barrel for my practice G 19...

    Are +P loads within SAAMI specs?

    I'm just asking because I normally don't mess with +P loadings, that's all.

    SGT, call your mfg. Get it directly from them. Can I use + P loads in (your specific gun)?

    Their answer will say a lot about your gun and the company.

    Every Glock Owner Should Know This!

    Shouldn't you be asking why?


    [​IMG] EVERY GLOCK OWNER SHOULD KNOW THIS!

    Glock uses polygonal rifling. This is a type of rifling where traditional lands and grooves are replaced by "hills and valleys" in a rounded polygonal pattern. (Usually a hexagon or octagon)

    [​IMG]

    Conventional rifling on the left, Polygonal rifling on the right.

    Lead bullets and polygonal rifling (from Wikipedia)

    The manufacturer Glock advises against using lead bullets (meaning bullets not covered by a copper jacket) in their polygonally rifled barrels, which has led to a widespread belief that polygonal rifling is not compatible with lead bullets. Noted firearms expert and barrel maker, the late Gale McMillan, has also commented that lead bullets and polygonal rifling are not a good mix. However, since neither H&K nor Kahr recommend against lead bullets in their polygonal rifled barrels, it is probable that there is an additional factor involved in Glock's warning. One explanation is that Glock barrels have a fairly sharp transition between the chamber and the rifling, and this area is prone to lead buildup if lead bullets are used. This buildup may result in failures to fully return to battery, allowing the gun to fire with the case not fully supported by the chamber, leading to a potentially dangerous case failure. The other explanation is that Glock's barrels may be more prone than normal to leading, which is the buildup of lead in the bore that happens in nearly all firearms firing high velocity lead bullets. This lead buildup must be cleaned out regularly, or the barrel can become constricted and result in higher than normal pressures.

    The .45 caliber Glocks have octagonal rifling vs the hexagonal rifling in the other calibers.
    The octagonal rifling provides a better gas seal in the large caliber .45 ACP. Notice how the image on the right has a lot less space between the bullet & barrel compared to the image on the left:


    [​IMG]

    Polygonal rifling is very different from conventional rifling. There are no distinct transitions between the lands and the grooves. The illustration below shows the polygonal rifling in a Glock 9mm LUGER pistol.

    Every Glock Owner Should Know This!

    [​IMG] EVERY GLOCK OWNER SHOULD KNOW THIS!

    Do Not Shoot Reloads (Weakened Brass)

    GLOCK Warranty; The use of reloaded ammunition will void the Glock warranty.

    If you want to shoot reload or lead ammo you should install an aftermarket barrel.



    Do Not Shoot Reloads (Weakened Brass)


    Glocks have an unsupported chamber.

    First of all "unsupported chamber" is a misleading term: all barrels must support the round in the chamber. Furthermore, all guns that use the modified Browning action have _partially_ supported chambers. In order to make the Glock function reliably with the widest possible selection of ammunition it has a "less supported" chamber than other guns. This is why reloaded ammunition is not recommended in Glock pistols. If you choose to shoot reloads, please consider an aftermarket barrel.

    [​IMG] [​IMG]

    Note the unsupported brass with the Glock compared to the Springer XD.

    This is why I shoot only factory-new ammo and retired my G22 to house gun status.

    Sgt,good post by Crane, due to the rifling on Glocks barrels it's not good to use any lead bullets( Gold dot's are not,in any pressure),I live in South America where factory ammo isn't cheap so for my practice Glock I got an aftermarket barrel with conventional rifling to shoot lead if i ant,and my carry ammo is obviously factory with the standard Glock barrel.
    People talk good about 124 +P Gold Dots,I wish they where easier to get down here...My humble piece of advice,try them at the range to see how the recoil/flash departments suits you...

    Cane, do you have any experience with HSM ammo? Here is a link.

    Retail Ammunition | The Hunting Shack






    I shoot their 10mm ammo out of my glock. It is remanufactured ammo. I have shot about 1100 rounds through my Glock20. Is this safe? Thanks:D

    I'm not familiar with the brand.
    At 1K + rounds I would guess one of three things, you have an aftermarket barrel, you keep a clean weapon or, you probably won't have a problem.
    With that said, I would strip the G20, brakeclean the barrel and scrub with a nylon stiff brush. Get an eye loupe (magnifying glass) and inspect the barrel at the throat with extreme prejudice. If it looks good get some die makers ink (or a blue magic marker) and cover the entire area, them wipe with a cotton cloth. If the blue doesn’t wipe off dampen (small steps, little water) the cloth and try again. If the blue remains try a wet nap (alcohol wipe) and see if any cracks show up. (Poor man’s magna flux) No spider cracks, just keep doing what you have been as far as maintenance. Continue the inspection with every strip down.
    Call HSM and tell them you’re a loyal customer and this is the info you have just discovered. Let them tell you their take on the glock issue. Base your future purchases on their response.
    Remember the photos in my post are for my G22 chambered in 40 S & W. When you have your G20 stripped, drop a round into the chamber and check the unsupported case area. I have no experience with 10 mike mike. You may find this a non-issue. Although you should check your chambers (and clean with a chamber brush, which is bigger than a bore brush, See .45 ACP Chamber Cleaning Tool) on all guns for the spider cracking. It’s just common sense. COMMON SENSE WENT INTO EFFECT AT 0600 hrs THIS AM!

    Be safe out there and please use you’re most powerful weapon first, your brain!

    I posted earlier:
    Since no one answered my question, I did some research on my own and found that +P loadings are within SAAMI specs. Since the Glock 19 is designed to withstand SAAMI pressures, I would go ahead and run the +P loadings without any worry. Stay away from lead loadings and +P+ loadings. You will risk blowing up your Glock 19.

    P.S. Thanks for making me work to get my answer, canebrake. Geez, you're about as useless as buying condoms for eunuchs.

    :D

    Thanks for all the info you posted about the Glock safety issues. That is great info for everyone to pay attention to.

    Another newbie question. How do I tell if it is a lead bullet or not? If it is FMJ with a copper jacket, I'm good, right? So many companies make 9mm rounds, it's a lot harder to find a good brand than when I'm looking for Fiveseven ammo which is only made by 2 companies and meant specifically for my weapon (and the P90). What are some good reasonably priced brands of 9mm rounds that are OK to put through my Glock at the range? I'm already pretty much set on the Gold Dot .124 gr +P, but I'm still looking for some good range/practice ammo to use.

    anywayz.............

    I asked if the loads were within SAAMI specs (DURRRR). SAAMI specs don't change depending on the manufacturer, silly..............:D

    Heck, most companies will probably say "No" just to be "lawyer safe".

    You did redeem yourself with the great info about the Glock pistols, though.

    Funny, Colt said shoot the damn +P and the +P+ if you want!

    We have a covert component called quality.

    Something the other manufacturers seem to skimp on.

    A guy I know told me that a friend of his heard from a guy who read on the internet (Are you with me so far?) that the issue with +P isn't so much with overpressure, but heat. Or for Canebrake, erosion over explosion.
