My bf's glock issue: Glock 23,gen 3. While firing at the range, a round (a reload) fired, but failed to eject the spent round. I manually pulled slide back and chambered the next round. The weapon failed to fire, leaving no strike mark on the primer...I worked the action a second time, and again the weapon failed to fire. I unloaded the weapon, and loaded a (factory round) and again, it failed to fire with "no markings" on the primer. Has anyone had the same issue with their Glock? any help or suggestion's would be appreciated. Thank you!
