Search the law enforcement website of the state where you purchased the gun to see if it offers an online service. Check Third-Party Websites Websites such as HotGunz publish databases of firearms that owners report after they realize a gun has been stolen.
These sites are not tied to any law enforcement agency and aren't a substitute for an official police trace, but they are quick to use and can provide some valuable information. Simply input the gun's serial number into the search field to see if your weapon is listed. A Note About Vintage Guns Vintage and antique guns may not have the serial number printed on the gun's body, because they were manufactured before the legal requirement to do so. To identify the make and model of these guns, dig around the manufacturer's website. Alternatively, take the firearm to a gun dealer who specializes in antique and collectible guns.
He or she should be able to research the gun's history and provide the make, model, date of manufacture and original owner specifications, for a fee.
