I'm holding a real pm2 in my hand right now. The only differences I can see are the notch at the base of the blade (but that could have been a modification), and the edges/corners around the lock cutout (mine's completes smooth). If that's a fake, it's crazy close to the real thing.
You need to look closer. We shouldn't be listing all of the ways that the fakers can improve their products to deceive people but there are probably a half dozen other aspects of the knife that are indicators that it is fake.
