Many of the Kabooms were experienced with jacketed ammo. No lead is involved there. The Glock was designed for military purposes using FMJ bullets. They can shoot many thousands of them with NO maintenance. I NEVER use lead for any of my semi-autos. To do so means you take your chances and suffer the consequences. The tradeoff of cheaper ammo is risk of destroying your gun. Something I won't chance. Wanna kill these ads? We can help!
