A couple of threads have discussed the the fact that some folks have experienced a painful trigger finger when firing the Walther PPS M2. I decided to write Walther about this issue to see what they would say. I received the following email this morning from a service tech at Walther:
"I know what you’re referencing. I have the same experience shooting this gun.
Can you please focus on pressing toward [sic] more toward the top of the trigger?"
So there you have it. They are aware of the problem and the solution is for the user to resolve.
