I had a couple of shooting buddies who had FNH 5.7s with threaded barrels and suppressors, but they got rid of them after a year because of the ammo scarcity and cost. That was 3-4yrs ago, so maybe that unusual caliber cartridge is more widely-available these days. A very nice piece, but I’d rather have the Kimber 1911.
Yep, ammo is the problem.
