Decoding the FEG Hi Power is also a very good resource that covers the FEG made copies of the Hi Power.

The FEG P9 is a very faithful copy of the pre Mk II Hi Power and has 100% parts compatibility.
The first generation P9M is a P9 with a 1911 style slide release an extended safety, and larger 3 dot sights. Other than the slide release and smaller cut in the slide, it has 100% parts compatibility with the Hi Power.
The second generation P9M uses a S&W locking system and while it looks like a Hi power it isn't and has very little parts compatibility.
Unfortunately KBI imported all of them as the PJK-9HP, so it gets confusing.
FEG made Hi Powers for both military and civilian contracts and produced them to the customer specifications with blued or parkerized finish, wood or plastic grips, round or spur hammer, and in the P9 or either P9M configuration. Their commercial pistols were almost always blued, but you'll otherwise find the widest variety in the commercial pistols as companies like KBI often were not picky about the specifics and FEG used whatever parts were on hand.
This is a commercial P9 made for KBI but it has the later P9M extended safety and larger 3 dot sights. The polish and blus is quite good and the over all quality is excellent. The FEG pistols all came with the Pre- Mk II humped feed ramp which can cause issues feeding some hollow points, but I've had excellent reliability with all four of the FEGs Hi Powers I have owned with both Hornady XTPs and Remington Golden Sabers.
I converted a P9M to the SFS Hi Power configuration to match my factory FN SFS Hi power. Other than having to fit the restyled DFS slide stop to the 1911 style slide cut, it was no different than fitting the SFS parts to any Browning Hi Power, requiring some minor hand fitting of the safety.

FEG also made counterfeit Browning Hi Powers for sale to mid eastern nations under arms embargoes. These have browning roll marks but can be identified by their B series 5 digit serial numbers (an FEG format). The idea was that if these arms were captured FEG would have plausible deniability.
FEG also sold FEG marked Hi Powers directly to Israel and later supplied complete parts kits to Israel for assembly in Israel. This culminated in the the Israeli Kareen.
The Hi Powers that have been imported in the last few years from Israel include a mix of FN made Hi Powers, FEG made Hi Powers, Kareen Hi Powers and some FEG counterfeit Hi Powers that were probably captured by the Israelis. Condition of these imports however is generally poor.
KBI also imported parts from FEG with the final machining and assembly completed in the US, with KBI selling them under their Charles Daly brand. The first 500 or so were completed by Dan Wesson and and the remaining 2500 or so were completed by Magnum research. These are very well made Hi Powers. The Charles Daly Hi Powers were discontinued in January 2008 and at the time they sold for around $400, compared to around $600 for an FN/Browning Hi Power. At $400 KBI was losing money on them, and at much more than $400, customers were opting for a Browning or FN made Hi Power.
KBI closed its doors in January 2010, and FEG nearly went bankrupt around the same time and stopped producing the P9 and P9M at that time. With FEG out of the Hi power business, FN/Browning Hi Power prices started climbing - to the point they stopped selling them in large enough numbers to warrant production. Competition is a good thing.

The Argentine FM (Fabrica Militar) Hi Power was made under license from FN from about 1970 to 1990 and this included final inspection by FN staff. These Argentine made Hi Powers are actual licenced made Hi Powers meeting FN acceptance standards.
However, when that agreement expired in 1990, FM started making a clone of the Hi Power, the FM 90 with some changes such as a more 1911 looking slide. FM also started making the FM 95, a compact version of the Hi Power in 1995. The fit and finish on the FM 90 and FM 95 isn't up to FN standards but they are still good shooters.

There are a lot of FN and Browning made variants including wartime Nazi marked Hi Powers made by FN as a subsidiary of DWN, wartime Inglis made No 1, No 2 and No 2 Mk 1* Hi Powers for Chinese, Canadian and British contracts, later British L9A1 Hi Powers, a large number of FN Hi Powers made for various police and military contracts, many with their own serial number series, the commercial C and T series Hi Powers and the later MK II and the stronger cast frame MK III Hi Powers, the latter also available in .40 S&W with a heavier slide, and the SFS Hi Power, and in epoxy and various polished blue and nickel plated finishes.

Now that FEG and FN have both discontinued the Hi Power, TISAS (Trabzon Silah Sanayi A.Ş) is now making a clone of the Hi Power called the BR9 Regent. It has MK III features such as the flat feed ramp, but an older style flat safety lever. It also has dovetailed 3 dot sights but appears to be using proprietary dovetails dimension rather than the Novak dovetails used on the Mk III.
I haven't shot one of these yet, but it's on the list. Bill Laughridge from Cylinder & Slide has had nice things to say about them and other than using a slightly larger sear pin and the sights, they appear to have full parts compatibility with the FN Hi Power and are reported to be very well made. They also have a stainless steel version, which is a first for the Hi Power.
As much as I love the standard Hi-Power, I really love that shorter Detective model. 
, and the equally-awful trigger. I wish I could say removing the mag disconnect is all you need to do to tidy up the trigger. It’s not. I like Cylinder & Slide’s hammer. Never yet been pinched by mine, and looks great on the gun, IMO. I’m not a big fan of the Browning ambidextrous safety lock, which is shamefully ugly on an otherwise beautiful gun, but it works - I guess.
