Firearms having a barcode on an external surface and methods for producing the same

Abstract

Firearms having a barcode on an external surface and methods of providing the same are disclosed. An illustrated firearm includes a substantially even exterior metal surface that has a barcode formed therein. The barcode includes fine grooves or bars such that the exterior metal surface appears raised in an area of the barcode.

1 . A firearm comprising: 
 a substantially even exterior metal surface; and    a barcode, formed in the even exterior metal surface, the barcode including fine grooves or bars such that the exterior metal surface appears raised in an area of the barcode.    
     
     
         2 . A firearm as defined in  claim 1 , wherein the barcode includes information and provides an at least partially non-reflective surface for the firearm.  
     
     
         3 . A firearm as defined in  claim 1 , wherein the barcode comprises a substantial portion of the exterior metal surface.  
     
     
         4 . A firearm as defined in  claim 1 , wherein the barcode subdivides the metal surface.  
     
     
         5 . A firearm as defined in  claim 1 , wherein the firearm is an automatic pistol further comprising: 
 a plastic handle; and    a slide.    
     
     
         6 . A firearm as defined in  claim 5 , wherein the barcode is located on the slide.  
     
     
         7 . A firearm as defined in  claim 1 , wherein there is no color contrast between the barcode and the exterior metal surface.  
     
     
         8 . A method of manufacturing a firearm comprising: 
 providing information to be encoded onto a firearm;    providing an exterior metal surface on the firearm; and    performing a laser treatment to the exterior surface of the firearm to brand the exterior surface with a barcode including the information.    
     
     
         9 . A method of manufacturing a firearm as defined in  claim 8 , wherein performing the laser treatment forms the barcode and dampens light reflection from the exterior surface.
