IF you want to safely shoot reloads, lead or jacketed, for your own protection and SAFETY....change the barrel to an after-market barrel that has been heat treated !
Far too many GLOCKS have been blown up with Factory loads...even more with reloads !
Glocks barrels DO NOT support the rear of the case like SAAMI spec replacement barrels.
PLEASE heed this warning and be safe !
