883937 - Trigger Valve

The trigger mechanism actuates the trigger valve inside the gun when you pull it, which fires the driver and drives the nail/staple. There are two types of triggers: “sequential” and “contact”. Contact triggers allow you to “bump fire” the gun: just hold the trigger down and fire multiple nails at a time. Sequential triggers require you to first press the nose to the medium before the gun will fire, so it allows you to fire only one nail at a time.
