I've been comparison shooting the two versions of the PPS, along side a XDs 3.3, all in 9mm caliber.
For the Walthers, the triggers and sights are the same. But the frame shape and mag release on the PPS M2 is so much nicer that I plan to sell my original model PPS.
And I am not sure about the XDs. I sure like that red fiber optic front sight. And the larger mag capacity. But the trigger is slightly beat out by the Walther trigger.
It is possible that I'll sell the XDs also and just look for a fiber optic sight for the PPS M2. I really can't see that I need 3 small single stack 9mm pistols.
In the very small double stack category, the SIG 290 seems to be the one for me.
The problem with owning many different guns is keeping track of the different trigger pulls. The PPS and the 290 couldn't be more different in that regard.
