I have a 1.0C and a 2.0C in 3.6". As noted, one is 12 round vs. 15, but a FS mag w/ spacer works for either. Personally, the 15 round mag and 3.6" makes a very comfortable combo. The 12 round mag is better for CCW, but also stubbier and harder for me to shoot w/o the pink extension.
A little polishing, and Apex when needed, gets either to a smooth/crisp trigger pull. The 1.0 still has the trigger bar loop, which allows some adjustment to where the sear breaks in the trigger pull. The 2.0 doesn't have that flexibility. Mine breaks at the very back after dropping the apex sear in, which suits me fine. Apex has a longer disconnect for their flat face trigger option, which has the sear breaking forward in the trigger stroke. Wish they would offer that disconnect separate as it can be modified to tailor the breaking point.
Both have been a bit tedious in finding a decent load that meets my accuracy expectations. Had to go with either a storm lake or Wilson aftermarket barrel drop in. Both have a 3.6" barrel so the same aftermarket barrel works for both. Still playing with the 2.0, which seems to shun my go to 115jHP reloads and prefers 124JHPs.
If your preference is the 12 round mag for CCW, I would seriously look at the FNS9C vs. the M&P 1.0C. I love my M&Ps, but for a compact or FS 9mm, would take the FNS hands down. Mine has ambi mag release, ambi safety, and came with 3 mags. Accuracy is very good right out of the box and didn't require any tinkering. I did have a trigger job done on each, which wasn't expensive and amounted to changing out a couple springs. The trigger pulls are simply equal to or better than an Apexed M&P.
