I REALLY like my CM9. Crazy accurate and a pleasure to shoot. I had no problem adjusting to the trigger, either.
As for your "first round FTF problem" (I assume that you meant "failure to feed", right ?).... if that is so, I have a solution. I just went through this with my CM9, which is essentially the same pistol as the PM9.
Check your magazines - how difficult is it to load the last round ? If it is quite difficult, as compared to the rest of the rounds, then you have the same problem as I had. To fix this, just remove TWO coils from the mag springs, then re-bend the cut end to match the original shape. This will relieve the excess spring force on the top round, which should then strip out of the mag perfectly.
My CM9 is now 100 %. Feeds perfectly, every time.
