This has nothing to do with shooting lead bullets through a barrel with ploygonal rifling. Different problems. Shooting lead build through a barrel with ploygonal rifling causes increased barrel pressure, not KB's in the chamber from increased pressure.The Glock barrels are not full case suport barrels.
There is a small portion of the case that is not in the barrel.
The problem is when you hot load your ammo.
If the case fails you will rip the mag out (it will spit it out ),ammo rolling around on the ground and a good powder burn. Buy an after maket barrel and your good to go.
