Push the hammer back into the trigger guard and do this again. No make sure that the safety is functioning properly by engaging the safety and attempting fire the trigger. If the safety is working properly the trigger will not fire while the safety is engaged. If the safety is not working properly please contact KIDD and we will assist with this adjustment.
