Hi guys, I am in a discussion with some stztange folks regarding legal ownership of firearms in the US. Maybe you guys could pass me some input. 1. Wich firearms must be registered when puchased? (revolvers, pistols, shotguns, etc.) 2. Can anybody let me know, how many crimes are done in the US with legaly owned firarms and with illegal firearms? It would be great if you could give an official refference (not from the NRA, but from the FBI or so).
