I also had a jam in my 10yr old G19. I am shooting reloads, but this was the first jam I've ever encountered. Tapping the slide did engage the live round, but I could not pull the slide. Knowing I had a live round chambered, I triggered and discharged the round safely. I do have a modified guide rod with a laser device, but it survived the tapping of the slide. Now the G19 works properly. Thanks for this forum!
