Gold Dot .123gr +P for a Glock 19
 
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.

You are fine,Glock pistols can take +P loads...

Crispy129 02-08-2009 10:45 PM

As long as their not lead. http://i695.photobucket.com/albums/v...icons/oops.gif

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...

Crispy129 02-09-2009 02:14 AM

Alright, so no lead bullets and I'm good?

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.

Shouldn't you be asking why?

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)

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:

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.

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.

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.
