New York has not attempted any kind of audit of the manufacturer-supplied samples and exhibits from guns, though this is an acknowledged source of mix-ups. The basic logistical problem with such a hypothetical audit is that it would require voluntary cooperation by gun owners to turn over their firearms for new test firings. Likewise, CoBIS is limited in its capability to answer research question due to limitations on data collected. CoBIS personnel do not know how many guns recovered by the State Police were actually sold in New York State, since those data go through separate clearinghouses. Their rough impression is that the guns tend to not be “imports” from other states, but rather the use of old existing guns. Moreover, although information on the gun is recorded in the database, ammunition brand is not, though some technicians will enter that information in IBIS as comments if it is known. All that is generally recorded in CoBIS is make, model, serial number, and caliber; any other information is gathered by the permits office.

In the 2005 legislative session, bills offered in the New York State Assembly suggested a range of legislative responses to the CoBIS database, from a complete repeal of the enacting law (A05093) to multiple-phase expansions in scope to include additional classes of firearms and ballistic images of bullets for those weapons that do not eject shell casings (A00968, A06462). None of these was enacted. In the 2007 session, A07477 would expand CoBIS to include rifles and shotguns.
