M&P9 m2.0 Apex upgrade question

[dustinb43]

I have an M&P9 m2.0, i want to get the Apex trigger upgrade, but on apex it says the following for the action enhancement kit:

*This kit REQUIRES the use of the larger 1/8 inch sear spring and plunger set up. If your M&P has a 1/16th inch diameter sear plunger and spring, we strongly advise you upgrade to a new style sear housing block before installing this product. All function and reliability testing was done with a 1/8 inch sear plunger and spring, therefore we cannot guarantee proper function without the appropriate size sear plunger and spring. Modern sear housing blocks can be found on Brownells.com and other online firearms product retailers.

brownells has the sear housing block:
SMITH & WESSON SEAR HOUSING BLOCK ASSEMBLY, STANDARD | Brownells

my question is, how can i tell if my M&P has the 1/16th or the 1/8th?

It's determined by date of manufacture.
I had to call S&W this AM about a few things. I saw your post before calling them and added your Q? to the ones I asked. S&W tech dude stated the M&P changed to 1/8" in 2013.
