Make use of the NICS system mandatory, but open it to private gun sellers. [View all]

[friendly_iconoclast]

Use the carrot and stick approach to encourage use:

1) Civil and criminal immunity for those transferors who properly use it.

2)In addition to whatever penalties entail from not using it, make the illegal transferor
accessory before the fact for whatever crimes may be committed with the gun(s).

I suspect most opposition to this would come from A) FFL holders who would miss
the corporate welfare, and B) antigun types who feel this doesn't restrict guns enough.
