Reddit reviews DECODING THE FÉG HI-POWER

So those, I believe are FEG P9F's imported by Mauser. It's definitely not a Hi Power clone like the early FEGs which have interchangeable parts with FNs and are true clones. This gun is more like they took a S&W Model 39 and put into a vaguely Hi Power shape.

Great little $0.99 PDF that started as a forum post but is definitely worth reading for anyone interested in FEG.

It depends on when it was made. Some versions are very similar while some are direct clones of the HP. The Argentinian FM Hi Powers are direct clones and should accept all BHP parts.

There's a good book out there that has some production details: https://www.amazon.com/DECODING-F%C3%89G-HI-POWER-Jerry-Paregien-ebook/dp/B00DKB3LXY

My understanding was that there was a good website but the guy who made it wrote the book.
