Every gun maker out there disclaims reloaded ammo- that is their lawyers talking.
Glocks (as he said right up there) use a different style of rifling. They should not fire unjacketed lead bullets. But the Blazer is a jacketed bullet.
Left to right- lead bullet (truncated cone) jacketed lead bullet, jacketed lead hollow point bullet. All 3 are 9mm Parabellum.
