Looking at the wrong places. There are two dead giveaways on fake pm2's.
1. Fakes use stamped liners because they are a lot cheaper. Stamped liners don't have the little notch seen in the circled areas.
2. They also do not bother with the cutouts or they do them differently. An authentic PM2 should have 3 cutouts as indicated in the pic by the yellow lines.
As a 3rd giveaway, I don't think I have seen a fake PM2 in an upgraded steel yet. They usually just fake the s30v versions. However, I am not 100% on this. The things in the pic though I am sure about.
EDIT: Yes, it is real. I didn't see your
