I am not an experienced Glock person, so I am really not sure what happened. I took the brand new, unmolested, not even taken down yet, glock to the range today. I put about 200 rounds through it. About half way through that, the pistol didn’t fire. The trigger wasn’t cocked. It had cycled fine otherwise. There was a new unfired round in the chamber. I dropped the mag and checked. It ran fine after that. I have never had something happen like that before.
