Looks? Meh. The grips look better than the PPQ. They are taken from the Q5 Match SF. The bowed out areas for the serrations are a pass. I like the Walther logo in the middle like that though. I wouldn't discount it for looks. It's just not a must have atm.
Brain farther, forgot PPQ made the switch.
The paddle is so much smoother and faster. I couldn't find a PPS that didn't come with an outrageous price so now I have to accustom myself to a button again with my Shield.
