SurvivalBlog's view that these have no traction and why:

I often have SurvivalBlog readers forward me alarmist e-mails, warning of "total disarmament" of the civilian populace. While there indeed may be plans or schemes to disarm Americans, I don't consider these threats credible. Let me explain why: I would conservatively estimate that there are about 316 million firearms in private hands in the United States. Of these, less than 10% are logged in any formal registry. Perhaps another 30% have Form 4473s filed with the FFL dealers where they were first purchased, but that is a fractured mishmash of records with a quite perishable life span. It is notable that we live in a very mobile society, where most families move every three or four years. And in most states, there are no record keeping requirements for secondary sales of firearms. So to call the accumulation of 4473 forms a de facto registration system is laughable.

A Congressional Research Service report provides these details:

The National Institute of Justice (NIJ) reported in a national survey that in 1994, 44 million people, approximately 35% of households, owned 192 million firearms, 65 million of which were handguns. Seventy-four percent of those individuals were reported to own more than one firearm. According to the ATF, by the end of 1996 approximately 242 million firearms were available for sale to or were possessed by civilians in the United States. That total includes roughly 72 million handguns (mostly pistols, revolvers, and derringers), 76 million rifles, and 64 million shotguns. By 2000, the number of firearms had increased to approximately 259 million: 92 million handguns, 92 million rifles, and 75 million shotguns. By 2007, the number of firearms had increased to approximately 294 million: 106 million handguns, 105 million rifles, and 83 million shotguns.
