Overview

This drop-in spring kit is intended for M&P pistols used in duty or carry roles, offering replacement components that can refresh worn factory springs while supporting a more refined trigger setup. It includes a trigger return spring, a slave pin to assist installation of the return spring, and one sear spring. The kit is designed to fit all M&P pistols, including recent and older manufacture, but it will not fit pistols adapted for sale in Massachusetts. For shooters looking to maintain their pistol with factory-style replacement parts, it provides a straightforward upgrade path without changing the platform’s basic setup.

Considerations & Trade-offs

  • This kit is limited to M&P pistols and is not compatible with pistols adapted for sale in Massachusetts.
  • It is a spring-only replacement set, so it addresses trigger-related components rather than broader pistol setup or performance changes.
  • Installation is intended as a drop-in replacement, but the included slave pin is specifically there to help with the trigger return spring installation.
  • The Duty/Carry kit does not include the competition striker spring mentioned for the separate Competition Spring Kit.
