The J-Frame Duty/Carry Kit is the next evolution of drop in parts from ATS, Inc. Installation of this kit reduces the trigger pull weight of your centerfire J-Frame* Smith & Wesson Revolver from over 12 lbs to 9lbs.
This kit contains a new Rebound Slide Spring, Main Spring and an Apex XP Firing Pin kit. Installation requires no fitting or modification to the factory springs or parts, just remove the factory parts and install the J-Frame Duty/Carry Kit.
*Works with all modern* centerfire J-Frame revolvers with the frame mounted firing pin.
