Glock Supported Barrel ?

[The Cold Lake Kid]

I finally broke down and bought a Glock to play with.
A Glock 19 Gen 4
I heard of someone selling supported barrels allowing the safe use of reloaded 9mm cartridges and even lead bullets.
Does anyone know who this is?

More than likely Storm Lake, KKM et al.

it was only earlier gen 2/3 .40s that did not have the fully supported chamber. Glock gen 4 19s should be fully supported but it has polygonal rifling so lead wouldn’t be great to use.

<SNIP> but it has polygonal rifling so lead wouldn’t be great to use.

Why is this? I don't have a Glock; I do have a Jericho with a polygonal rifled barrel, and all I shoot is cast lead, un-jacketed DRG lubricated cast bullets. No issues, no leading issues, no accuracy issues, just a great shooting pistol!!! I think the cast lead myth in Polygonal barrels is just that; a myth.

Well, I followed up with FOC and ordered a barrel they recommended for my use of reloaded and lead bullets: Rival Arms Gen 3/4 SS PVD 6 grooves with 1:10 twist.
Now just waiting for the Ontario CFO to process the paper work.
7 weeks now and counting.
I'm looking forward to trying it out. It's been a long time since I shot a Glock.

Here is a Gen3 35. Well supported. My 9's are just as good.

It's not a myth but it is a bit overblown. By simply running a bore brush through the barrel every now and then while shooting lead you can completely avoid any of the supposed issues. I find the whole aftermarket barrel thing with Glocks to be total nonsense unless you are looking to load ammunition that is beyond SAAMI or CIP specs.

Even then, at least IME, it's not worth it. I did thousands and thousands of rounds of testing years ago and at the end I sold all my aftermarket barrels once I realized stock was actually best despite the supposed experts on the internet. Glock's design is pretty good. Their engineers spent more time on things than any of the folks saying you "need" an aftermarket barrel.

Now ya tell me! LOL
Any recommendations on lead bullet weight for the 9mm Glock?
I usually load and shoot .45's. I just hope my old arthritic, fumbling fingers can manipulate those little 9mm cases.!!

I use the LEE 124 RN myself. Shoots fine from my 17 and 48. I powder coat mine so lead deposits aren't an issue. If you shoot traditionally lubed bullets be sure to quickly scrub the barrel every 100 rounds or so.

Not a myth at all. I once had the acquaintance of a friend show me his Glock 17 barrel which was so fouled that he thought the steel in the bore was peeling off. I picked at the separating metal and it turned out that the polygonal 'grooves' had accumulated such thick deposits of lead that it was starting to separate from the interior of the steel barrel in such a way that it appeared the metal was peeling from the bore. Turns out he had fired hundreds and hundreds of lead bullets without cleaning the gun.

Factory Glock barrels will shoot conventionally lubed lead bullets just fine but the barrels do need to be cleaned frequently due to the above situation. I now powder coat nearly all my pistol bullets which avoids the leading problem.

I'm not sure if all polygonal barrels are created equal so maybe this doesn't apply to Jerichos but it can be an issue with factory Glock barrels.
