I often see tv shows where the lab traces the registration on a pistol or rifle to track down the owner. Even here in Canada you can't trace a long gun as none of them are registered. Legally owned handguns are registered and can be traced to the last owner. However, most pistols used in crimes aren't registered at all or in a very small number of cases were stolen from the legal owner. I am curious if long guns and handguns are in fact registered and traceable in the States like the csi type shows claim or is it just more tv bs? Thanks.
