FAQ

Will this work in an original M&P (non-2.0)?

Not directly. The kit is designed for M2.0 frames. For original M&P pistols, you must upgrade to a modern sear housing block (1/8-inch sear plunger/spring) before installing. Without that swap, function and reliability cannot be guaranteed.

Does this require any permanent modifications to my pistol?

No. All parts are direct drop-in replacements. No filing, drilling, or permanent fitting needed. Can be removed and factory parts reinstalled.

What pull weight should I expect?

5.0–5.5 lbs. as installed. Actual weight may vary slightly depending on sear housing block condition and lubrication. All testing was performed with 1/8-inch sear plunger/spring.
