Representative Miguel Garcia (D-Bernalillo) has introduced Bill 44 that would prohibit anyone except a licensed dealer from selling guns at a gun show.

From NRA-ILA:

Although HB 44 contains language that would require improved reporting to the FBI of persons prohibited from purchasing firearms and protect against the development of any registry of lawful gun buyers by state or local agencies, make no mistake: gun control remains the centerpiece of this very flawed legislation.  This will be just the first step toward banning ALL private gun sales and transfers – in fact, that’s exactly what the original language of HB 77 did when it was introduced last year!  If enacted, gun control advocates will check this scheme off their list and they will move toward gun bans and magazine limits, just like in Colorado.
