The Norwegian Initiative on Small Arms Transfers (NISAT) provides an extensive file collection and database on the legal and illegal trade in small arms and light weapons.
This is the world's only on-line global database of small arms transfers. It contains 1 389 355 records detailing transfers between some 250 states and territories over the period 1962-2015.
Unfortunately, due to a lack of funding, as of October 2017 this database is no longer being updated.
