Action Enhancement Trigger Kit 



For Use In These Guns:

For use in all M&P M2.0 polymer frame pistols in 9mm, .40S&W, and .45ACP, including the Full Size, Standard, Compact, and Subcompact.

EXCEPT for the Shield and Shield M2.0.

Also for use in the original M&P 45.

Does Not Fit These Guns:

Not certified for use in the M2.0 Metal Series models.

Not certified for use in the 10mm models.

NOT for use in the original M&P in 9mm or .40S&W.

Not for use in the Shield or Shield M2.0

The Action Enhancement Trigger Kit is engineered to provide the M&P 2.0 pistol owner with a smooth, consistent 5.0 to 5.5 lbs. trigger pull with the advantages of shorter over-travel and shortened trigger reset.

All of the components work together to provide a pull weight within the acceptable range for a top end, service pistol.

When installed this drop-in trigger kit will:

  • Reduce trigger pull weight by approx. 1 lb. to 5.0-5.5 lbs. range
  • Reduce pre-travel and over-travel by approx. 20%
  • Deliver smooth uptake and reset with crisp trigger break
  • Maintain factory safety values with center mounted pivoting safety
  • Direct drop-in replacement parts, no fitting required


  • This kit REQUIRES the use of the larger 1/8 inch sear spring and plunger set up.
  • If your M&P has a 1/16th inch diameter sear plunger and spring, we strongly advise you upgrade to a new style sear housing block before installing this product.
  • All function and reliability testing was done with a 1/8 inch sear plunger and spring, therefore we cannot guarantee proper function without the appropriate size sear plunger and spring.
  • Modern sear housing blocks can be found on Brownells.com and other online firearms product retailers.
