I checked out the PPS at a gun store last week. Finally found one after like 6 months of searching.
It will fit in your pocket no problem.
I think I'll pass on buying one for now though. I'm not experienced enough with guns to really feel comfortable shooting guns that aren't full grip yet (even though I have small hands). I'm plenty happy with my new glock 19 and think my next gun will be a glock 38.
Reviews on the guns seem pretty good, but there have been some issues I believe related to the larger grips.
If you are interested in a pocket gun, take a look at the Kahr 9mm's too.
