I use mine with the basting gun, too, not just safety pins.
I push the needle all the way from top to bottom and back to the top, use the Kwik Klip to push the fabric to the base of the needle and pull the trigger.
If you have a nut pick (seafood pick) you can use the handle on that, too - it's got nice ridges to cradle the pin on the safety pin or the needle on the basting gun.
