So you pulled the triggeer when you shot the window out thinking the gun wa unloaded. That makes more sense. Just a suggestion I would send it bck to the vendor with maybe a phone call first detailing all the trouble you are having. I sure wouldn't continue to shoot it in its unsafe condition. (Any airguns with trigger failures are dangerous!).

Thanks for the explanation and remember that gun safety rules apply to airguns too. Just using a gun that you deem unsafe is a violation of those rules. Good luck in the repair.
