Detailed Features 

 
The full-size grip ships with interchangeable backstraps so you can fit the gun to your hand size. The Armornite finish resists corrosion without adding bulk. As a striker-fired pistol there is no manual thumb safety; the trigger pull is consistent shot to shot. At 17+1 capacity, you can put a meaningful number of rounds downrange before reloading. 
 
The optics-ready slide uses an adapter plate system compatible with common miniature red dot footprints, so adding a reflex sight is straightforward without machining.

Owners of the M&P 2.0 Gen 2 Optics-Ready generally speak well of it. The grip comfort and ergonomics come up most often -- the interchangeable backstraps let most shooters find a natural fit without modification.

Accuracy with a mounted optic is a consistent talking point. The optics-ready feature is one of the main reasons people choose this pistol over comparable striker-fired options, and most find the adapter plate system easy to use.

Reliability with a wide range of ammunition is another theme in owner feedback; feeding problems are uncommon.

The main complaints center on weight -- at about 44.8 oz loaded it is on the heavier side compared to some polymer-frame competitors -- and trigger pull weight, which some shooters find heavier than they prefer. Neither criticism is universal, but they come up often enough to mention.
