I just bought the cm9
I was in the same position, I was looking To buy a used pm9. I went for a new cm9 for 150 bucks less. I bought a holster and a ct laser guard with the difference. The pm9 looks nicer and has smoother edges but I'm glad I went less expensive. A new pm9 was going for 280 bucks more than a new cm9. My cm9 has 300 rounds through it and not one problem. I'm sure you will love both, i wanted the pm9 but when it came down to spending the money I went with the cm9 and accessorized it and am thrilled.
