The trigger pull of the guns is usually manageable to most people though some might have difficulty getting used to the SubCompact at first. Some people say that double action trigger pull of the SubCompact could decrease the shots precision a bit. However, you are still able to fire the SubCompact accurately in quick succession on single action mode.
