Drop-in replacement part designed to improve the tactile trigger reset on original Smith & Wesson M&P pistols. This component addresses the mushy, indistinct reset common to factory M&P triggers by providing a more positive, defined reset point. The magazine disconnect version retains full mag safety function.

Install Difficulty: 2 out of 5
Requires detail stripping of the M&P frame to access the sear housing block. Tools needed: 1/16″ punch, small hammer, slave pin (optional), and a non-marring surface. Expected install time: 15–30 minutes. Armorer-level knowledge of M&P sear block disassembly recommended.
Frequently Asked Questions
Will this work with an M&P 2.0?
No. This component is designed exclusively for original M&P frames. The 2.0 uses a different sear housing block geometry. Check your frame markings — if it says “2.0” on the slide or frame, this part will not fit.
Does the magazine disconnect version affect trigger pull weight?
No. This component only modifies the reset characteristics. It does not lighten or alter the trigger pull weight, pre-travel, or overtravel. Factory safety values remain unchanged.
Can I install this without removing the magazine disconnect?
Yes, if you order the magazine disconnect version. The part is designed to work with the factory mag safety mechanism in place. If you prefer to delete the mag disconnect, order the non-mag-disconnect version separately.
