The FEG P9 is a very close copy of the Pre Mk II Hi Power.

The first generation P9M is nearly identical to the P9 except for a 1911 style slide release lever, larger 3 dot sights and an extended safety. It's arguably a better shooter given those refinements.

The second generation P9M is not a Hi Power at all as it uses a S&W style locking system.

Unfortunately KBI imported all of them as the "PJK-9HP" and TGI imported them all as the "P9M".

I talk about them in more detail in this post, along with the Argentine FM Hi Power, and the "Kareen" version of the FEG Hi Power in its different forms:
