Make you an offer...you and yours abandon the RKBA group, quit smearing it and its participants, and I will quit posting here.
Note that I do support regulation changes including:
NICS checks or equivalent on all transactions, even private party transaction, inheritance, and gifts. My approach would be a Federal FOID that you would automatically get at 18yo so they are not a "firearms ownership licenses", a common objection to that approach. The check is then if the FOID is still valid for the sale to proceed. This is easy from the IT perspective. Note the NRA rejects the FOID approach.
Limitation of pistol magazines to what fits inside the grip of the gun. Require that new designs not support magazines that extend beneath the handle (BATF already has authority to force design changes). This is readily demonstrated by the Ruger line of .22LR handguns and the Astra 400/600. Grandfather or buy back at retail price non-conforming magazines. This approach also slows down magazine changes. Note that the NRA has rejected magazine limitations
All firearms must be secured when not in use, being cleaned, transported, etc. While California got stupid on parts of this, its the right thing to do. Some will miss their old time glass front display cases or wall rack, but proper security is a must. Would consider an exemption for non-functional devices. I believe the NRA has fought mandatory safes. It adds costs to gun ownership, but this has to be done.
Mandatory reporting of theft or loss. This is a no brainer. A number of pro gun people say they will report theirs missing to avoid registration etc. That should be felony country.
Enforce the existing Federal laws about false paperwork by purchasers. Bloomie and I even agree on this one
