    I have a S&W M&P .45 ACP pistol that I use for “COMPETITION ONLY”, and I was hoping you could tell me if you could install all the parts necessary to make this pistol have a better trigger let off (trigger pull). Thank you very much for your assistance!

    I have a S&W Sigma 40 and would like to purchase a trigger spring kit to reduce the trigger pull. Do you have anything like that?

    I recently purchased a S&W M&P .45 compact. Wanted to know if your trigger kit will work in this gun.Have been told that it willl NOT fit a compact.

    PLease clarify for me.

    I took my M&P .45ACP to a gunsmith for the DCAEK. What they gave me was the competition kit and now I have a 2.5 lb. trigger pull. I like it, but the reset is not distinguishable. Is it possible I need a Return Assist Mechanism? Will this improve reset? The 2.5 lb. trigger is awfully light. Is it possible to up the pressure to 4 lbs.?

    I have an M&P Compact in 9mm. Do your kits fit all M&P’s or is there one specifically made for the Compact? Thank you.

    Hi Scott,
    You put a ESP (Completely replaced the old trigger) in my M&P9 at the winter championships but there was a part you didn’t bring with you and I would like to order it. Let me know what it is and cost and I will send or call in my CC.
    Thank you

    Do your triggers work with the S&W core?

  12. paul - June 11, 2015 @ 10:55 am

    No, it does not.

  13. paul - June 11, 2015 @ 11:01 am

    The kits fit the compact models as well. Look to the “Applicable To What Gun(s)” section of the product info for full details.

  14. paul - June 11, 2015 @ 11:02 am

    Look here for M&P Shield trigger options.
