Yes, they are fantastic pistols. Great trigger, good ergonomics, run flawless, slim and light for carry behind the bino holster, stupid flat and accurate, and a great suppressor host. Feels like shooting a real life ray gun.
The only real criticisms I see with the pistol is that it is a bit loud (the gas ports act like a comp to a degree when it comes to the sound profile) and the magazines come a bit stiff. The latter seems to be easily fixed after leaving the mags loaded for a day or two. The argument that 5.7s are too expensive to train with doesn't hold as much water as it once did. The gap in ammo pricing between 9mm and 5.7mm has gotten much smaller over the past couple years.
The Walther PDP Pro and M&P 5.7 are the only two striker fired, polymer framed pistols that I still own. They stand above pretty much anything in their price ranges in my opinion.
