Does this kit include a trigger shoe?

Yes. The Polymer Action Enhancement Trigger includes the trigger shoe, trigger bar, and the center-mounted pivoting safety. The shoe is polymer with a textured face.

Will this reduce trigger pull below the factory safety threshold?

No. The kit reduces pull weight approximately 1 lb. below factory spec, staying within safe operational parameters. The Ultimate Safety Plunger and Performance Connector maintain positive sear engagement and drop-safety function.
