I may look at the 3.6" version when it hits Mass, but I just picked up a basically brand new 1.0 version with an Apex kit already installed and trijicon HD night sights installed
for less than what the new 2.0 costs. That extra 1/2 " in the grip isn't worth the cost to me with a shitty 10 pound trigger that I have to redo. The 4" version is almost as big as the full size M&P
with a little bit of a shorter grip.
I'm thinking only G19 fans are going to really jump on these, I wasn't sold on it, maybe the 3.6 version will have me singing a different tune, but the 1.0 I just bought
is a tack driver.
