I bought the gun directly from Cylinder & Slide. I've never handled a stock PM9. But the trigger pull is every bit as smooth as my S&W 686 revolver, and lighter to boot. I've owned over 100 firearms over the years, and this PM9 has the smoothest DA trigger pull I've ever experienced. When the trigger is smooth, it doesn't necessarily have to be light weight - the smoothness makes up for weight, yet you retain the safety of a heavier trigger pull in stressful situations. I don't have a trigger pull gauge, but I would guess this one is around 6-7 pounds.
The photos came out pretty small (I've got to work on learning more about posting photos). What you can't see very well is the polishing on the feedramp and the trigger face. If they weren't curved surfaces, you could shave using them as your mirror.
