Is it authentic M9 or COPY??

[Walkman]

It's my third generation PHROBIS M9! I spent RMB 7000 yuan (=US $875) for it, but I suspect it's not authentic knife coz the dolphin on the handguard is not very clear, and I'm not very sure how to distinguish authentic M9.

So, fine people help me to have a look over it and check it out whether it's authentic M9 or copy. sooo many thanks!

If you wanna see pictures of different angle, pls let me know and I will upload the pictures you need. Thanks again!
