Todd, Where can a guy get the MA compliant trigger bar and spring?

S&W says “factory installed only.”

Thanks

Mike B — It’s actually the MA-compliant trigger bar and trigger spring, which are different parts than the standard ones. They’re used in the gun to meet Massachusetts’ product liability laws, and increase the trigger pull. The Performance Center sear is just a different sear that S&W puts in the M&P9 Pro, it reduces the trigger pull and makes the reset more positive. The combination of the MA trigger bar/spring and PC sear is my personal preference.

Pepper — The combo I’m using gives a very strong, forceful trigger reset and more resistance in the trigger pull during the take-up, so in that respect it’s much closer to a DA revolver trigger. Bowie can, if you want, use the MA-compliant trigger bar & spring in conjunction with his normal action job to achieve basically the same results as I’m getting with the PC sear. In fact, Bowie can probably fine tune your trigger pull weight a little higher or lower based on exactly how he works the sear during the trigger job.

Todd,

Just sent my M&P9 off to David Bowie for a trigger job, but now you have me thinking that I might want to go with the PC+MA setup. I’m an old wheel gun man. How does this setup compare with a good double-action revolver trigger?

Thanks

I just picked up a M&P9 over the weekend and this website actually helped me to make my choice. I have a few questions about some of the changes made to the M&P9 used in the torture test:

(1)Is a Massachusetts trigger an actual trigger or is it an adjustment to the settings?

(2)What is a performance center sear?

(3)Are these changes necessary or user preference?
