As I understand the process you must also already know before you even apply for the permit the exact model you will be getting the permit for including the serial number of the gun. So basically you need to decide on and buy the handgun before you even go get your permit.I have not gotten myself a handgun permit but at least thats how I understand the process works. Someone please correct me if I am wrong.
You are right. You need to know all the registration information. Make, model, caliber, store, serial number.
Pretty much you buy the gun, or put a down payment, then ask HPD if your qualified to own it.
Wait the 14 days while they make up their mind and let you cool down in case you need to firearm to commit a crime.
Then they tell you ok, i guess you can have it.
You pick up the permit
Get your gun and show them the permit which says HPD says you can have it
Go back and stand in that long line again.
Repeat everytime you want a new one
