Just took possesion of this today. First one I ever owned. Shot a couple hundred rounds through it with zero malfunctions.
Well, I must say that the PC9 is unlike any other gun I have ever owned. It is a blow back gun, so the slide is massive!

The trigger and mag release are actually part of the stock:

And I still have not figured out exactly what this piece inside the receiver does:

Anyway, as I said, it functioned 100% reliably, with both my lead reloads and JHP reloads. The mag in this pic is a Mec-Gar 20 rounder, I bought two, and both functioned fine as well.

Think I forsee burning up copious amounts of 9mm through this thing! Now, if I can just find a rail to fit it so I can mount a red dot. This gun really would go well with a red dot.
