Went hunting yesterday morning and had a malfunction of some sort on the first ducks of the morning. When I pulled the trigger, nothing happened. I had cleaned the gun the night before and nothing seemed out of place. I had issues in the past with Federal shells but none since I had replaced all the springs. I did have a Federal in the chamber. I was able to rack the gun, eject the shell in the chamber and kill the pair of greenheads. The gun worked just fine after that, no malfunctions. Thinking back, I'm quite sure when I pulled the trigger, the firing pin did not drop but the gun was in full battery. The ejected shell had no light strike. I'm still scratching my head. The gun is a SuperX2.
