Reduction in Firearm Stock
It seems likely that Australia collected and destroyed well over a million firearms - that is, between five and six firearms per 100 people.
A commonly accepted estimate of the number of firearms in Australia at the time of the Port Arthur shootings is 3.2 million (Reuter and Mouzos 2003, 130). This suggests that post-massacre destruction efforts reduced the national stock of firearms by one-third.
If we accept a frequently cited estimate of 270 million privately owned guns in the United States (Karp 2007, 47), a similar effort in that country would require the destruction of 90 million firearms.
