So I guess the thousands of rounds of "lead" bullets I've put down range through my Glock 29 & Glock 20 should have caused it to go "Kaboom" long ago.
Buffalo Bore bullets and my personal cast bullets are hard cast, not typical pure lead bullets. They are perfectly safe to shoot in a Glock. And if your worried about shooting lead in your Glock, try cleaning your barrel once in a while. YMMV
