The Apex web site says the 1.0 triggers and kits will not work in the 2.0 and say the 2.0 triggers and kits will not work in other M&P pistols. The comments are with the description of each part or kit.

I only have M&P 1.0 pistols so I have not been able to make a comparison but I'd by the appropriate kit listed for the appropriate pistol.
