I just had the Apex Dceak kit install in my M&P 45 by John @ Remsport. Wow what a differance the trigger pull went from 9lbs to 5lbs along with a clean and very crisp trigger. I took the gun straight to a defencive class and the instructor was very impressed as well. If you have an M&P you need to get this kit! Can wait to get my M&P 40 done. John did it while I waited and you can beat that. Thanks John
