I have a rather beat-up Hi Power that I picked up a couple years back for a song...and am wondering a bit about it's origins. It was made in Argentina. Most of the Argentinian Hi Powers I've heard of have been referred to as "FM"s. Mine is marked F.N. Browning, Armscorp, Silver Spring MD, Made in Argentina. Is it the same thing as an FM, or is it something different? No matter what its history mat be, it's a fantastic shooter, and I love it to death...am just somewhat curious about it.
