As far as I'm concerned, it's simple: Ban high capacity magazines, ban

10. That's right: it's illegal unless you hold a Federal Firearms License.

Those licenses used to be very easy to get, but that was changed years ago. Now the only people to have the "standard" (not Curio and Relic only, which is only usable for very old, antique guns) FFL are those who are indeed truly in business. No more "coffee table" FFL dealers out there...

Non-FFL holders have to take delivery of their purchase through an FFL dealer, who must perform the federally-required background check and any other locally-mandated steps. In other words, these sales are subject to the same regulations as most other sales (and more so than are required between private individuals face-to-face).
