There are some options:
The Browning and FN Hi powers: I have a couple Mk III Hi Powers and an FN SFS Hi Power. It hard to go wrong with an original.
The FEG Hi Powers
I also have three FEG Hi Powers, but it’s important to understand they come in three different flavors.
The FEG P9 is a very faithful copy of a pre-MK II Hi Power with 100% parts interchangeability.
The first generation FEG P9M had a 1911 style slide release lever. The corresponding small triangular notch in the slide means the slide and slide release lever are not interchangeable with a Hi Power. They also had an extended safety lever and higher profile three dot sights. Those features are also often found on P9 pistols as well (as is the case in the previous picture).
Converting this 1st Gen P9M to SFS configuration required reprofiling the slide release lever if I wanted to use it. The other fire control parts required no more than with any Browning or FN Hi Power.
The Second generation P9M looks like a Hi Power externally but uses a Smith and Wesson style operating system. Consequently parts compatibility is fairly low.
If an FEG “Hi Power” looking pistol doesn’t have the little cross bolt oval in the frame on the right side, it’s a second Gen P9M and is not a Hi Power.
There is also the FEG P9R that is often confused with the P9M. But it’s more of a knock off of the S&W 59, a double action pistol that looks more like a S&W 59 than a Hi Power.
The Girsan Hi PowerThe standard models Girsan makes look like faithful Hi Power copies and have a good reputation so far.
However they also have sold a couple variants on the compact theme that FM pursued after their manufacturing license with FN expired.
Girsan makes a Defender (PI) model that is a compact Hi Power with magazine safety and no beaver tail. However they also make the MC P35 PI LW match with an alloy frame beaver tail and pre- deleted magazine safety. It’s been a superb pistol and is my current concealed carry pistol. At 21 oz empty it is about 8 oz lighter than a standard Hi Power.
The Springfield SA-35:Springfield had some teething problems with the pistols but those have been resolved. I’d buy one if I wasn’t already top heavy with Hi Power pistols. I’d also buy one in preference to FN’s new version of the Hi Power.
