Can I shoot lead bullets in my Glock barrel? - GlockPost
Hard lead bullets & a factory Glock barrel - Glock Talk
Shooting reloads with Glocks. . . - TheFiringLine Forums
For what its' worth. I'll personally never fire anything but factory ammo in any of my Glocks with factory barrels. Limits the risk of me being injured or ruining my pistols. That being said, we all make our own choices. I have heard of those with no issues shooting reloads in their Glocks. Again...for what it's worth that I posted some links for you. I cannot say one way or another. Be careful, be safe.
