Kent..I fired one, for a few hours, a few months ago, in Arizona... basically it is a 20 round staggered mag which looked to be under made the round is the 5.7x28 mm and shoots the SS190 ball ammo, it was said it will defeat most military body armor, as well as the new kevlar helmets....it had low recoil, and no muzzel climb...giving quick follow up shots...but the muzzel blast was LARGE... did a little night time shooting....and found this not to my liking !!! comes in double action only and I found the trigger, to need some work, but I tent to shoot custom single action autos...so I am bias, trigger work, would be a must for me. the weighed was about a pound and one third, empty... and a little over a pound and a half loaded...so about 30% less then most 9mm. Designed for defeating body armor so a high fps design, one that would not work with any current sound suppression designs, shy of maybe the VHF sonic models. At the time I was told, it would not be released to the general public... to me, it lacked the old class of the FN, and was just a new tool, for the tool chest. .......Pax
