No, I got it from a fellow on the M&P forum. Just FYI, it did not work, I ended up putting the Apex spring back in. If you look at the S&W .PDF parts lists for the M&P, you see that have 3 different trigger bars listed. I found the MA TRS would not fit right and was preventing the trigger from reseting because it was rubbing or contacting someplace near the top of the trigger itself. I gather there is a fix for this if you are willing to take an Xacto kinfe to your trigger innerds, which I am not. I may try and order the correct MA trigger/trigger bar from S&W, if it is not a "restricted part". S&W seems to have alot of "restricted parts" for these pistols.
