NICS - Can be done while you wait at the shop, no need to involve HPD at all or tie up their resources that could be better allocated to say, fighting/solving/investigating actual crime.
That would be fine if HPD only ran NICS checks. They check your doctor, the Hawaii Health Department, the Hawaii criminal database, etc. Would anyone outside of HPD have access to do all of that? Would we want LGS workers to have that kind of access to personal info? With NICS, all they see is a yes or no from the FBI.
Also, the 2 week wait is supposedly needed to run all of those checks and follow up with the applicant if there are questions (needs a mental health clearance letter, court records need corrections, ...). The 3-day NICS check time limit would not be adequate if all the same agencies are contacted.
Then there is the finger printing. At least your first application in this state would require a PD visit to do that.
The whole process is far beyond a NICS background check. Lawmakers have locked-in the county PDs as the sole provider for permit processing.
What about private sales? Would HPD still do those permits? What about Long gun permits being issued without a pending purchase?
As for registration, having the gun shops do that only works for the guns they sell. Private purchases would have to be handled somewhere, too, and the LGS isn't going to do it for free.
Plus, as an FFL (Federal Firearms Licensee), having them generate a registration for guns might violate the prohibition against the federal firearms registry. I'm sure if the system resides with the state, and the FFL is only inputting data, it might slide.
At this point, the whole permit application, background check and registration process would have to be overhauled to accommodate LGS doing them, and the private sales would have to be rolled up into it as well.
It's a can of worms .... figuratively speaking.
