I got a spot I decided to shoot my 10mm glock 29 that I just transferred from my friend. I started to shoot the hollow points he had in the mag and after the 5 shot I had a ammo malfunction. I took a closer look and noticed powder all over the inside of the gun took it apart and looked through the back of the barrel and noticed the bullet is lodged in the barrel. I tried to remove it but cant, why did this happen was it a bad round or primer so it looks to be a trip to the gun shop to see if he can dislodge it and see if the barrel isn't ruined. Any ideas or help to what caused this would be great.
