         7 . The silencer of  claim 1 , whereby open channels ( 31 ) are formed on either one or both sides of the silencer insert ( 30 ) that end in the shot channel ( 23 ). 
     
     
         8 . The silencer of  claim 1 , whereby at least some of the channels ( 31 ) are connected with each other. 
     
     
         9 . The silencer of  claim 1 , whereby the silencer insert ( 30 ) is removably arranged in the silencer housing ( 20 ). 
     
     
         10 . The silencer of  claim 1 , whereby the shot channel ( 25 ) is formed at least partially in the silencer insert ( 30 ). 
     
     
         11 . The silencer of  claim 1 , whereby exactly one gas expansion chamber ( 25 ) is formed in the silencer housing ( 20 ) and whereby exactly one silencer insert ( 30 ) is arranged in this gas expansion chamber ( 25 ). 
     
     
         12 . A firearm, in particular a handgun, comprising a silencer of  claim 1 . 
     
     
         13 . A silencer insert ( 30 ) for a silencer ( 10 ) of a firearm, in particular a handgun, whereby the silencer insert ( 30 ) is adapted to be arranged in a silencer housing ( 20 ) of the silencer ( 10 ), whereby the silencer insert ( 30 ) comprises a stable material with high open porosity. 
     
     
         14 . The silencer insert of  claim 13 , whereby the material of the silencer insert ( 30 ) consists of at least one of the group comprising
 metal, in particular aluminum, copper, zinc, nickel, iron, or a combination thereof,   ceramic,   carbon,   and combinations thereof.

         17 . The silencer insert of  claim 13 , whereby the pores and/or cavities formed in the silencer insert ( 30 ) are connected to each other and the environment in such a way that gas expanding in the silencer housing ( 20 ) is absorbed at least partially by the silencer insert ( 30 ) during an expansion phase and thereby slowed and/or cooled. 
     
     
         18 . The silencer insert of  claim 13 , whereby open channels ( 31 ) are formed on either one or both sides of the silencer insert ( 30 ). 
     
     
         19 . The silencer insert of  claim 18 , whereby at least some of the channels ( 31 ) are connected with each other. 
     
     
         20 . The silencer insert of  claim 13 , whereby a shot channel ( 23 ) is formed in the silencer insert ( 30 ). 
     
     
         21 . The silencer insert of  claim 13 , whereby the silencer insert ( 30 ) is formed in one part. 
     
     
         22 . Use of a stable material with high open porosity as the silencer insert ( 30 ) for a silencer ( 10 ) of a firearm, in particular a handgun. 
     
     
         23 . The use of  claim 22 , whereby the material consists of at least one of the group comprising
