Brownells 75th Anniversary - A Shooting Heritage


  • Includes forward set sear, trigger, striker block kit, and spring kit
  • Striker block kit includes striker block, spring, and talon tactical tool
  • Spring kit includes 4 and 5.5lb  trigger return springs, trigger return spring install tool, sear spring, and ram spring
  • Results in trigger pull weight near 4lbs for competition or 5.5 for duty/carry
  • Smooth uptake and reset
  • Total trigger travel of .120"
  • Improved safety features make the FSS a reliably safe trigger system
  • Works with all Smith & Wesson M&P pistols in all centerfire calibers and configurations except M&P Shield
  • Requires the use of the sear housing block designed for the large size sear plunger and spring (current production as of June, 2011)


  • Forward set trigger reduces trigger pre-travel and over-travel
  • The center mounted pivoting safety bar prevents unintended operation by creating a trigger block that will not disengage unless the shooter places their finger on the center of the trigger and encourages trigger manipulation directly in line with the bore axis 
  • Forward set sear shortens the stroke of the trigger pull by dropping the striker at a point farther forward than the factory sear
  • Forward set striker block has an improved radius on the striker block face that produces a smoother trigger pull and eliminates most false reset issues
  • This kit produces a smooth 4lb. trigger pull for competition or 5.5lbs for duty/carry use

Does not fit M&P 2.0 Pistols
