Abstract

A firearm firing pin system upgrade kit that improves trigger feel and easily converts for heavier or lighter trigger pulls. In some embodiments a kit which eliminates a previously required component. In some other embodiments a kit which can be mailed in a letter envelope.

What is claimed is: 
     
         1 . A firearm Drop-In Improved Trigger Pull Firing Pin System Conversion Kit comprising:
 at least one Spring Cup Aligning Washer (SCAW), at least one Compression Adjusting Shim (CAS), and at least one Half Spacer Sleeve (HSS);
 the SCAW configured as an intermediary between Spring Cups and a Firing Pin Spring of a firearm and additionally configured as a front/distal stop for the Spring,
 the SCAW further configured to isolate the Spring Cups from a Spring Cup Misalignment Bias induced by the Spring, 
 
 the CAS configured as an intermediary between the Spring and the HSS and further configured as a rear/proximal stop for the Spring, 
   the Kit configured to adjust compression of the Spring by incorporating additional SCAWs or CASs.   
     
     
         2 . A firearm Drop-In Improved Trigger Pull Firing Pin System Conversion Kit comprising:
 at least one Spring Cup Aligning Washer (SCAW), at least one Compression Adjusting Shim (CAS), and at least one Half Spacer Sleeve (HSS);
 the SCAW configured as an intermediary between Spring Cups and a Firing Pin Spring of a firearm and additionally configured as a front/distal stop for the Spring,
 the SCAW further configured to isolate the Spring Cups from a Spring Cup Misalignment Bias induced by the Spring, 
 
 the CAS configured as an intermediary between the Spring and the HSS and further configured as a rear/proximal stop for the Spring, 
 the HSS configured to be shippable within a letter envelope, 
   the Kit configured to adjust compression of the Spring by incorporating additional SCAWs or CASs.   
     
     
         3 . A firearm Drop-In Improved Trigger Pull Firing Pin System Conversion Kit comprising:
 at least one Spring Liner Eliminating Spring Cup Aligning Washer (SLESCAW), at least one Compression Adjusting Shim (CAS), and at least one Half Spacer Sleeve (HSS);
 the SLESCAW configured as an intermediary between Spring Cups and a Firing Pin Spring of a firearm and additionally configured as a front/distal stop for the Spring,
 the SLESCAW further configured to isolate the Spring Cups from a Spring Cup Misalignment Bias induced by the Spring and additionally configured to eliminate a Spring Liner of the firearm, 
 
 the CAS configured as an intermediary between the Spring and the HSS and further configured as a rear/proximal stop for the Spring, 
   the Kit configured to adjust compression of the Spring by incorporating additional SLESCAWs or CASs.   
     
     
         4 . A firearm Drop-In Improved Trigger Pull Firing Pin System Conversion Kit of  claim 3  where the HSS is configured to be shippable within a letter envelope.
