         8 . A firearm sound suppression device comprising:
 a tubular body portion defining an entry aperture and an exit aperture;   one or more baffles disposed inside the tubular body portion at locations along the length of the tubular body portion, the one or more baffles including:
 a central aperture; and 
 one or more through-channels disposed between a first surface of the one or more baffles oriented at least partially towards the entry aperture and a second surface of the one or more baffles oriented at least partially towards the exit aperture. 
   
     
     
         9 . The firearm sound suppression device of  claim 8 , wherein the one or more through-channels include:
 a through-channel opening in the first surface; and   a through-channel opening in the second surface that is aligned with the through-channel opening in the first surface.   
     
     
         10 . The firearm sound suppression device of  claim 8 , wherein the one or more through-channels include:
 a through-channel opening in the first surface; and   a through-channel opening in the second surface that is offset from the through-channel opening in the first surface.   
     
     
         11 . The firearm sound suppression device of  claim 8 , wherein the one or more through-channels include:
 a plurality of uniformly distributed through-channels.   
     
     
         12 . The firearm sound suppression device of  claim 11 , wherein the plurality of uniformly distributed through-channels of each baffle of the plurality of baffles has a common rotational orientation. 
     
     
         13 . The firearm sound suppression device of  claim 11 , wherein the plurality of uniformly distributed through-channels of each baffle of the plurality of baffles has a distinct rotational orientation. 
     
     
         14 . The firearm sound suppression device of  claim 13 , wherein a through-channel opening on a second surface of a first baffle is aligned with a through-channel opening on a first surface of a second baffle. 
     
     
         15 . A firearm sound suppression device comprising:
 a tubular body portion defining an entry aperture and an exit aperture;   one or more baffles disposed inside the tubular body portion at locations along the length of the tubular body portion, the one or more baffles including:
 a central aperture, 
   wherein the entry aperture, the one or more baffles, and the exit aperture are co-aligned to form a bore through the firearm sound suppression device, and   wherein the one or more baffles have a porous construction.   
     
     
         16 . The firearm sound suppression device of  claim 15 , wherein the one or more baffles having a porous construction include:
