Good afternoon everyone! S&W Customer Service Tech. Stated that the New Style Trigger Shoe can NOT be installed into the Older versions of the 2.0's.
I have had the 2 Individual New Style Trigger Shoe M&P's OR now for about a week. Run flawlessly within the 300 rounds put through them!
I have noticed that there is a little bit less pretravel on them both. One has a little bit smoother Trigger, but NOT as noticeable/positive Reset right out of the box than the other one. The One with the better reset, has a little bit more of a gritty pull to it, but it is smoothing out with a lot of dry-firing and shooting it. They both have less over-travel due to the small over-travel bump molded into they frame. Shooting them both is a pleasure and the ergo's and the natural point of aim, makes 10 yard shots easier/faster than any Glock I have, and have shot.
I would say, make the purchase, you won't regret it. The trigger will smoothen out with Dry-fire and rounds down range. You could also do the .25 polish job on it to help the process along. I haven't done it yet, but I might!
