glock/polygon barrles (reloading)

[GoneSouth]

I was always told not to use reloads in my Glocks. The range I used to go to would not even allow me to shoot reloads in my Glocks while at the range. They said it was a safety issue, but never elaborated. Later I heard sometimes Glocks go Kaboom with reloads b/c the chamber is not fully supported. After hundreds of rounds of reloads being shot over the years with Glocks, I had a kaboom a few years ago. Unsupported rim blew out and sent gas everywhere. Pushed the magazine out of the gun onto the ground. Pretty scary, but no evidence of any gun damage. I have heard you can buy aftermarket barrels with fully supported chambers. For me, I am sticking with factory loads.

Never heard that before. I must just be lucky, I have three glocks that have shot thousands of rounds and I’ve never bought factory ammo

This! Lots of info on the Glock forums about this.

What generation? The older .40's did not have supported chamber, so the brass would get the "glock bulge". Anything gen 3 and up doesnt have the issue.

What was the story on the ammo? Did you load it? Lots of variables here.


And pretty much every firearms manufacturer says not to use reloads.

Was your kaboom a 40 cal with reloads?

[Bigfootwolff]

It was a Glock 19, 9mm.

Can you elaborate please, were these loaded by you?

The reloads I shot that caused the failure were purchased at a gun show several years ago, and were brass with 115 grain FMJs. Can’t recall which vendor they came from. They were in an all white box with a 50 round styrofoam insert. There was a large blue stamp on the top that read 9mm 115gr FMJ. Shot a lot of those rounds in my Glock and only had that one Kaboom.

I think the polygonal rifling doesn’t like hardcast, right? Regular lead bullets are fine, because they are soft, but hardcast, like what you’d use in a revolver or a barrel with cut rifling are not a good choice for standard Glock barrels. IIRC, this was part of the reason people bought the Lone Wolf barrels for their 20’s, as the cut rifling was better for 10mm heavy hardcast hunting loads

Edit: apparently I was wrong. I was going off conventional wisdom from back in the Gen2/Gen3 days. Lots of info online about safely shooting hardcast through a standard Glock barrel. This is good, because I’ve got a crapload of 95gr hardcast .356 bullets from a 380 I used to have, so these can be loaded into 9mm for plinking.
