Somebody read it on the internet and started the rumor.

Gocks have what's called polygonal rifling that differs from traditional rifling. It makes for a tighter gas seal when shooting copper jacketed bullets. This is why you can achieve higher velocities (and sometimes better accuracy) with a Glock barrel. They are not suitable for lead bullets. Lead is soft and can seal too tightly causing higher pressure. This can damage the barrel. It can also (in rare cases) damage you. I've seen first hand barrel bulges that have resulted from shooting lead in a Glock barrel.
DON'T DO IT. If you absolutely must shoot lead out of your Glock then buy an aftermarket barrel with regular rifling. I hear Lone Wolf makes a good one.

I have shot thousands of light load 9mm lead bullets with no affect on accuracy or pressure. The polygonal rifling is not the best for lead and accuracy. Regular rifling is best for lead, but if I can consistently hit an 8 inch steel target at 25 yards with the Glock barrel and lead bullets, I'm not complaining.

I put a lone wolf in my 19 even though I had heard from several people that they had shot thousands of rounds of lead through theirs. The potential results of a problem were just too high.

My Glock/lead experiment
OK. My lead bullets were very hard, so I just had to experiment and shoot ten - 10 - lead bullets this afternoon through my stock Glock 20. Never again. Hard lead (18 from Missouri Bullets), properly lubed by MBC, correctly loaded/seated by yours truly . . . and a lead mine in my barrel. Leading like I have never seen and after only 10 bullets.
That's enough for me. No more lead in my Glocks. Actually, no more lead period. Cannot see buying another gun or even a barrel just to shoot lead bullets. That said, they were not smoky in the least and were deadly accurate.
It seems that some can shoot lead in Glocks with stock barrels - and do shoot many thousands of lead rounds successfully - and some cannot. I, unfortunately, am in the latter category.

I don't know about the XD part, but I am sure that my leading problems were just something I did wrong. Wrong powder, wrong speed of bullet. Something. The good thing about experiments is that I did learn something for me personally: it is true that Glocks and lead bullets do not mix.

Also, isn't there a problem with unsupported chambers? The Glock chambers have more tolerance to make them more reliable. Every once in a while I'll get a batch of brass that I can tell has been fired from a Glock because it has the "Glock bulge." I know shooting reloads from a Glock is a problem because of the rifling, but sometimes factory ammo can go "BOOM" too because of the chamber issue.larry s goldstein said:
I have a Glock 29 that I reload for. I bought a KKM barrel when I got the Glock and have shot all of my reloads from that barrel.

For what it is worth --- If you research this issue, you will see that almost ALL the reported KBOOMs are with the Glocks chambered for 40S&W. When I first started shooting Glocks (9mm, 40S&W, 45ACP) I was concerned about this. Went out a bought Lone Wolf barrels for the Glocks ... However, I have shot many cast boolits through the 9mm and 45acp using the factory Glock barrels without problem. Just do not shoot the 40S&W that much so I can not comment on how they shoot cast boolits.
As for Glock saying don't shoot lead - Glock says DO NOT USE RELOADS period - cast or otherwise. However, almost every manufacture says the same thing .... I know for a fact that Springfield does!!
Cast boolits can be a little tricky and WILL deposit lead in your barrels if not done properly. They must be correctly sized for your barrel, must be of sufficient hardness, must be properly lubed, and you should pay attention to velocities and pressures generated from you load. If anyone of these are compromised, leading may occur. A cast boolit that shoots well in one gun, may actually deposit lead in another. I have a 9mm Beretta '92 that seems to eat almost every lead boolit without problem as long as I size them to .357. On the other hand, my S&W 9mm M&P likes 9mm sized to .356.

Well they are welcome to do whatever they feel is right. I wouldn't ask them to do otherwise and hope they wouldn't give me a hard time for doing what I feel is correct. With my wife and kid shooting this rig the stakes were just too high for me no matter how many testimonials I saw on the net. So I bought a Lone Wolf.
And I traded for the gun used at a price that it was still a decent deal with the extra $100 thrown in there for the barrel.

So does this mean I should have kept my sigma instead of getting this glock? If glocks are so intolerant to reloads how are they still such a highly praised gun? I don't see how it is such a great gun if all you can shoot are factory FMJs and still not even be sure that things won't go bad. I know bad things can happen to any gun but there just seems to be so much more drama about glocks. Can someone fill me in?
They're not intolerant to reloads, just sensitive to reloads with a LEAD bullet. If you're reloading jacketed bullets, you're fine. If you're shooting lead, you can either stop and run a bore snake or something through the barrel pretty frequently and make sure there isn't excessive lead fouling, or get an aftermarket conventionally rifled barrel and shoot all the lead you want.Lt.Dan said:
There are lots of guys out there shooting lead through factory Glock barrels, but they're keeping a very close eye on the leading.
