DISCONNECTOR TEST: Slide forward, hammer back, thumb safety OFF. Grip gun normally with firing hand, while pulling slide back 1/4" with support hand. Pull trigger. Hammer should not fall. Repeat test by pulling slide all the way back, then releasing it slowly, pulling trigger every 1/2" of slide movement. The hammer should NOT fall until the slide has returned to the full forward position. If it does then the disconnector is worn. DO NOT fire the pistol until it is repaired, or else it may possibly go into firing uncontrollable bursts or go completely "full-auto".
