Glocks

Jacketed ammo (of any stripe)...... Yes

Lead ammo....... No..... Unless you change the barrel (that is from Glock, not the barrel part, but the "no" part)

No Pistol manufacturer will warrnety their firearms barrel if you shot reloads out it. There are too many variables with people loading their own rounds.

Cheers!
 
Glock pistols use polygonal rifling, and therefore it is not recommended to use straight lead rounds. Due to excess fouling caused by straight lead, resulting in increased pressures in the barrel, one must shoot at least a semi-jacketed bullet through all polygonal rifled barrels. This includes Glocks, select H&K pistols such as the USP and the P2000, and the Baby Eagle/Jericho series.

As previously noted, however, Glock, like all other manufacturers, will consider their warranty void if reloaded ammunition is used in their products.
 
Repeat a myth long enough and it becomes accepted as truth...
Most manufacturers state that reloaded ammo voids the warranty - that choice is left to the owner. Normal.
Yes, you can use reloaded ammo in a Glock. I've been doing it for years for thousand of rounds without any issues in stock and after market barrels - with lead bullets ranging from 115-147 gr. So has hundreds of other shooters. My first G19 had in excess of 40k of lead reloads through it - not a mark in the barrel.
No, it's not a good idea to use pure lead reloads, but no commercial lead bullets are pure lead - all are a mix to increase the hardness.
And before anybody jumps in and mentions the "unsupported" chamber and blow-ups - two or three recorded cases - seen with thousands of guns & millions of rounds. Statistically insignificant - it can potentially happen on any firearm.
So, if you are careful, accurate, and use proper equipment i.e. exercise your due dilligence with your reloading, you should have no problems.

It's a lot cheaper which means you can shoot more - enjoy!

I shoot lead out of my Tanfoglio .40 cal with polygonial rifling and have yet to see any evidence of leading in the barrel. To say you cannot shoot lead in polygonial barrels is not true. The Tanfoglio barrels handle it with ease.

The Glock barrels which are cut differently than the Tanfoglios and do have issues with lead though I have friends in the US who shoot lead all the time out of their Glocks with no issues. My friends do clean their guns after each range session which for reasons only the gods know, some Glock owners seem to believe they never have to clean their guns. This might account for the stories about lead build up in their guns.

I have just started down this road as well - in face of the numerous horror stories not to.

2000 rounds has worked just fine with plated bullets. Haven't tried lead.

Even after 2 firings I have yet to measure the dreaded "glock bulge."

Maybe it shows up later or with really hot loads. But my caliper and my eyes have yet to see it.

After reading all the stuff on the web I was pretty sure I'd be buying a new gun by now.

Note: Usual reloading caveats apply. Information is provided for entertainment purposes only. No warranty is implied. Each gun/bullet/component interact differently with each other. Start low with established loads and work up at your own risk.

Can you use reloaded ammo in a Glock? I couldn't afford to use my Glock, if you couldn't. I'd say I've run about 95% of rounds through the gun were reloads. Don't tell anyone, but I'm gonna try lead bullets next :eek: I've done enough reading, especially on castboolits forum, that I feel comfortable enough to try them in my 45 acp Glock. Supposedly the 8 sided ploygon barrel is less prone to leading than the 6 sided ones found in the less manly calibers :nest:
 
You can put anything you want through your Glock. If you shoot lead bullets, just be very vigilant with your cleaning, due to the polygonal rifling.
 
Not long ago, I borrowed at G17 from a local dealer to do a holster cert course.
I used Wolf reloads - lead bullet- and shot blowouts all day at 15 yds and less.
Spoke to the Glock rep shortly after who advised that they do not recommend anything other than jacketed. He was actually quite adamant that I should not shoot cast.
Bought a G34 and used up the rest of My wolf cast reloads (600 rds) without a hiccup. No significant leading and excellant accuracy.
Shifted to AIM plated a little over 2000 rds ago, and have had no issues on accuracy or fouling.
I am NOT noted for obsessive gun cleaning (if you know what I mean).
I have a tendency not to get bogged down with the "prevailing wisdom" method of reloading evaluation, but much prefer to experience / evaluate performance myself.
Every case is unique..... The fact that members of CGN reload would lead me to believe that they are of analytical mind, and scientific method. ( at least those with all their fingers and eyeballs).
Do not believe me. or anyone else for that matter..... Experiment and experience for yourself (safely of course). the knowledge obtained through personal experience is the most precious, and certainly the most meaningfull.
If it were me....... shoot the he** out of it with cast and see how it works.
Unsupported chamber my a$$.
 
Unsupported chamber my a$$.
The definition of unsupported is when the chamber does not fully enclose the brass above the webbing. When this happens, the brass wall takes the pressure instead of the steel chamber. I have always assumed that this was a deliberate design tradeoff to ensure better feeding, given that the guns are geared for LE/MIL who shoot only factory - but it's not like Gaston told me this personally.

Some glocks are unsupported.

The Glock bulge is particularly noticeable in the Glock 40 cal. I use a Lee sizing die to remove it. Once they are fired in my Tanfoglio the bulge disappears and all is good.
