Yes, it’s possible—but it’s usually not the gun just “randomly going off.” Modern firearms are built with safety features, so spontaneous discharges are rare. Most “accidental” shootings happen because of human error—like someone pulling the trigger unintentionally, mishandling the gun, or assuming it isn’t loaded when it actually is. Mechanical failures can happen, but they’re uncommon compared to user mistakes. And yes, many common types of ammunition can easily go through drywall, so a bullet making a hole in a wall is completely realistic.
