Absolutely love the Walther PPS!
I usually carry the PPQ but I've had the PPS for about 4 years now and its one fine little handgun. Wife used it for her ccdw range test and is her preferred carry. I always carry it with the 6 round flush bottomed mag and carry the 8 rounder as a spare. Wife carries it with the 7 rounders only. With the 6 round mag it'll disappear in a pocket almost as nicely as the LCP though of course not quite. Its very thin and I really like how its nearly perfectly flat. I have the LCP but its hardly ever touched because of the size and flatness of the PPS. Another thing I really like about it is how tightly designed it is! As soon as you feel it you know its a quality handgun and it has the heft of a solid metal gun instead of a poly.
I see it's sales growing since Walther has lowered the PPS price AND brought the PPS M2 out with the button release which most Americans prefer. I'll stick with the Classic paddle versions for the PPS and PPQ however.
Mine makes it to the range regularly for a couple mags and when I first purchased it I put several hundred rounds through it each trip as I wanted to test its reliability. Its never had a failure nor has the wife's. Very easy to shoot and, for me, one of the most accurate subcompacts on the market. Many online reviews say the same.
If anyone is in the market for a small firearm they should really drop by a store (ie pop by and see Chris) and check one out.
If Chris has a paddle version in next time I drop by I might have to pickup one more.
