"Point Break" actor John Philbin was arrested Saturday after a domestic incident with his girlfriend that allegedly ended with him going for a gun.
Law enforcement sources tell us officers were dispatched to Philbin's L.A. home after they got a call that he and his GF were having a loud, heated argument.
When officers arrived ... they were told Philbin had been waving around a gun, and stepped outside his home with the firearm. We're told a neighbor eventually convinced him to hand over the weapon, and then he took a walk.
When Philbin returned home cops arrested and booked him for brandishing a gun.
He's still in custody.
