Action Enhancement Trigger Kit for M&P M2.0

This Action Enhancement Trigger Kit for the M&P M2.0 is a drop-in replacement system designed to reduce trigger pull weight to a consistent 5.0–5.5 lbs. range while shortening pre-travel and over-travel by approximately 20%. The kit addresses the primary complaint with the factory M&P trigger: a long, gritty pull and excessive reset distance. By replacing the sear, trigger, and striker block components with precision-machined parts, the kit delivers a smooth uptake, a crisp break, and a short, positive reset. Pull weight is reduced by roughly 1 lb. from factory spec, keeping the trigger within service pistol tolerances for USPSA Production, IDPA SSP, or duty use.

Platform Compatibility

• Smith & Wesson M&P M2.0 (full-size, Compact, and Subcompact variants)
• NOT compatible with original M&P 1.0 pistols
• NOT compatible with M&P Shield, Shield Plus, or Bodyguard series
• Requires 1/8-inch sear plunger and spring – verify your pistol’s sear housing block before installation

Key Features

• Drop-in fit – no fitting, filing, or polishing required
• Reduces pull weight to 5.0–5.5 lbs. (approx. 1 lb. reduction from factory)
• Shortens pre-travel and over-travel by approx. 20%
• Center-mounted pivoting safety maintains factory drop-safety values
• Includes sear, trigger, striker block, and all necessary springs

Install Difficulty: 3/5

Moderate. Requires detail stripping the M&P frame and slide. Tools needed: 1/16-inch punch, 3/32-inch punch, small hammer, and a slave pin or paperclip for the trigger bar spring. Armorer-level familiarity with the M&P platform recommended. If your pistol has the older 1/16-inch sear plunger and spring, you must upgrade to a 1/8-inch sear housing block (available from Brownells or other retailers) before installing this kit. The kit was tested exclusively with 1/8-inch components, and function cannot be guaranteed with the smaller plunger.

Frequently Asked Questions

Will this work in my M&P 2.0 Compact 4-inch?

Yes. All M2.0 variants (full-size, Compact, Subcompact) share the same trigger housing and sear geometry.

What is the reset distance after installation?

Reset is shortened by approximately 20% compared to factory. Expect a tactile and audible reset at roughly 0.15–0.18 inches of forward travel.

Do I need to replace the sear housing block?

Only if your pistol has the 1/16-inch diameter sear plunger and spring. If you are unsure, remove the slide and measure the plunger diameter. The 1/8-inch plunger is standard on newer production M2.0s.
