Well, I bought a PM9 about 2-3 months ago, and loved the gun. I got a killer deal on a used all black one. Anyways, I was looking for a stainless slide model originally, and found a new one for a good deal and sold my Black model (which worked flawlessly). My new Stainless slide model does not want to feed the first round of a new mag very well. I know it's not worn in at all, but I didn't have any problem at all with my other model. I don't know why I can't just stick with what I have sometimes. Especially since I only made the change for esthetics, when noone really ever see's it except me. Hopefully this will work itself out with a few hundred rounds. I just really hope I didn't swap a sweet running gun for a problem gun only for looks .
