I'd like to refer you to the link below. This is a reloading board. Many knowledgable folks there.
They point up two Glock problems, you might want to be aware of. 1.) polyagonal barrels, 2.) chamber open to the bottom, allowing brass to bulge when fired.
The polyagonal barrel is a differnent type of rifleing, which leads to a looser fit between bullet and barrel - aledgedly! Also has been blamed for excessive lead buildup in the barrel especially when cast lead bullets are used.
The open bottom of the chamber was probably done to ease cartridge entrance to chamber. This however leads to the brass bulging into the open space when fired. If you're reloading that brass, it will be necessary to resize that brass to eliminate the bulge, or it won't fit back next time. Special dies, and possibly an extra step in reloading may be necessary, and brass life may be reduced (number of reloadings before you discard, or worse, have brass failure.)
