       8 . The firearm as claimed in  claim 1 , 
 the sear assembly further comprising a sear roller that is operably connected to obstruct the movement of the cocking piece until the trigger is pulled to a firing position; wherein    the sear roller comprises a low friction material.    
   
   
       9 . The firearm as claimed in  claim 8 , wherein the low friction material comprises a jewel material.  
   
   
       10 . The firearm as claimed in  claim 9 , wherein the jewel material comprises ruby, sapphire, garnet, or any mixtures thereof.  
   
   
       11 . The firearm as claimed in  claim 8 , further comprising a receiver, 
 the sear being connected to the receiver by a sear pin,    wherein one or more regions of the receiver contacting the sear pin comprises the low friction material.    
   
   
       12 . The firearm as claimed in  claim 1 , further comprising 
 means for providing one or more regions that are in contact with one or more pins comprised in the firearm with a low friction material.    
   
   
       13 . The firearm as claimed in  claim 12 , wherein the low friction material comprises a jewel material.  
   
   
       14 . The firearm as claimed in  claim 13 , wherein the jewel material comprises ruby, sapphire, garnet, or any mixtures thereof.  
   
   
       15 . A trigger mechanism comprising: 
 a sear assembly which comprises a sear;    a trigger assembly which comprises a trigger;    a firing pin assembly which comprises a cocking piece; and    wherein the sear assembly, the trigger assembly, and the firing pin assembly are operably connected to each other so that one or more rolling elements obstructs the movement of the cocking piece until the trigger is pulled to a firing position.    
   
   
       16 . The trigger mechanism as claimed in  claim 15 , wherein the cocking piece comprises the rolling element.  
   
   
       17 . The trigger mechanism as claimed in  claim 16 , wherein 
 the sear assembly further comprises a sear catch.    
   
   
       18 . The trigger mechanism as claimed in  claim 15 , 
 the sear assembly further comprising a sear roller that is operably connected to obstruct the movement of the cocking piece until the trigger is pulled to a firing position; wherein    the sear roller comprises a low friction material.    
   
   
       19 . The trigger mechanism as claimed in  claim 18 , wherein the low friction material comprises a jewel material.  
   
   
       20 . The trigger mechanism as claimed in  claim 19 , wherein the jewel material comprises ruby, sapphire, garnet, or any mixtures thereof.  
   
   
       21 . The trigger mechanism as claimed in  claim 15 , further comprising 
 means for providing one or more regions that are each in contact with a pin comprised in the trigger mechanism with a low friction material.    
   
   
       22 . The trigger mechanism as claimed in  claim 21 , wherein the low friction material comprises a jewel material.  
   
   
       23 . The firearm as claimed in  claim 22 , wherein the jewel material comprises ruby, sapphire, garnet, or any mixtures thereof.  
   
   
       24 . A trigger mechanism comprising: 
 a sear assembly comprising a sear and a sear catch; and    a trigger assembly comprising a trigger;    the sear assembly and the trigger assembly being operably connected to each other to provide a ratio of sear engagement to a trigger pull distance that is greater than or equal to 0.5 and less than or equal to 6.0;    the sear assembly and the trigger assembly being operably connected to each other through one or more low friction materials;    the sear engagement being an overlap of the sear and the sear catch; and    the trigger pull distance being a distance traveled by the trigger from a set position to a position which causes the sear and the sear catch to be disengaged from each other.    
   
   
       25 . The trigger mechanism as claimed in  claim 24 , wherein 
 the one or more low friction materials comprise one or more jewel pivots; and    the one or more jewel pivots comprise a material containing ruby, sapphire, garnet, or any mixtures thereof.    
   
   
       26 . The trigger mechanism as claimed in  claim 24 , further comprising:
