Went to my LGS  to set up a transfer and they had a new, extra, form to fill out for the sale. They said it is to be held tor the state if they ask. Not a formal form like the 4473, just a single page they print up that has all my info and the gun purchased. When did this go into effect? I asked, half kidding, if this was so they can come get it when they decide to collect them and I was told yes. Interesting.

Not new. Previously discussed in forum. Few were following but ISP reinforced need to comply when doing presentations on new gun dealer licensing.   This is the form also asking  reason purchased and occupation, right?

Thanks, been a while since i’ve purchased anything.
No sense living in fear of the mounting challenges to gun ownership.This is defacto gun registration at the state level. Nothing preventing the Isp from requiring FFLs to fax or email these in to create a data base for eventual forced collection.

Step by step.

Asked for price also.

Mandatory buy back?

Any cop now has full access to any of your info going forward. No warrant needed.

Link to details on this assumption?

Its only a few posts up in this very thread  Sections b and c would be relevant to your inquiry

(a) Any seller of firearms of a size which may be concealed upon the person, other than a manufacturer selling to a bona fide wholesaler or retailer or a wholesaler selling to a bona fide retailer, shall keep a register of all firearms sold or given away.
(b ) Such register shall contain the date of the sale or gift, the name, address, age and occupation of the person to whom the weapon is sold or given, the price of the weapon, the kind, description and number of the weapon, and the purpose for which it is purchased and obtained.
(c ) Such seller on demand of a peace officer shall produce for inspection the register and allow such peace officer to inspect such register and all stock on hand.

I thought this piece of law is superceded (pre-empted ?) by "... upon issuance of a warrant ..." or similar, no?

Wouldn't LEO's still need to have jurisdiction to inspect a dealer's records.  So local police, county sheriff, or ISP.

Probably. But Tango's point is still solid; which FFL is gonna say no to a badge? And the crooked cops know this
