I had a Brigadier back in the early 70s that fed everything reliably, but it was just too long of a grip for me so I sold it off. It used a modified Walther dropping block lock, which carried over to the 92 series of handguns. It was truly a beautifully made gun, though.
The Egyptians thought enough of it to produce a copy of it, the Helwan.
Steyr imported some "commercial" Helwans in the 80s that had some of the worst polishing I have ever seen on a new gun.
I believe Beretta made some Brigadiers for the Israelis, as well.
