Once you pay it off, just get the serial number, make, model, barrel length, and caliber of the handgun and get the permit to acquire. You don't HAVE to have the seller meet you at HPD, but it'll may make things smoother. If not, just make sure he signs the back of the Permit to Acquire and fills it out. If the seller doesn't meet at the range, gun store, or his house, it IS okay to do the transfer at a police station (did my F2F handgun transfer at Kailua substation) as a police station is one of the places you're allowed to take firearms. BK did remind of a very important step...once you have the permit to acquire, arrange with Kingkeoni to pay the KK tax and safety inspection.
