Well, that was really disappointing. I just got back from a gun store in town that had a PPS. Loved everything about it -- except that the trigger pull felt like it was about 9 or 10 lbs.! It was ridiculously stiff. No one in the store knew anything about a kit to lighten it up, and they didn't know of a gunsmith they'd recommend locally who might be able to work on it. I would have bought the gun if it had a 5 lb. trigger.
I'll write Walther (Smith & Wesson?). Maybe if they get enough complaints they'll come out with one with a lighter trigger, or at least a factory trigger kit to lighten it.
