Good pistol it fits the nitch of going through soft body armor if that interests you. The majority of pistol rounds will not achieve that kind of speed. I have heard people can shoot out to 100 yards with them accurately but have not seen anyone do it and I definitely can not. The 22 tcm is the only other modern pistol that will produce that kind of speed. Rock Island Arms sells a 22 tcm type 1911 that has a 9mm conversion barrel also. Elite ammunition and R&R Weapon Systems sell some very hot ammo for the 5.7. When things get crazy in 6 months due to the election panic you will be able to sell one on gunbroker for probably 500 to 700 more than you paid due to them being hard to get. I saw them go for over $2000 regularly in the last panic.
The problem with the FsN pistol is that the ammo that is available is weak loaded. If you can find some of the better ammo, than you are golden, but the premium you pay for those rounds is very expensive.
Especially the Elite Ammunition. There is only so much powder you can put into that tiny case to bump up velocities.
I would never recommend buying any firearm for resale value. Firearms are just like everything else...it's all about supply and demand. That product is only worth what someone is willing to pay for that item.
The recoil is very mild. When I had my FsN I also had the Kel Tec PMR as well in 22 mag. People would say they are equal and they aren't...22mag isn't close to what a 5.7 bullet will do. One is a rimfire and the other is a centerfire cartridge.
You can get distance with the FsN and I've seen folks shoot them to 100 yards. I never did as I felt that if I need to shoot a 100 yards, I need to grab a rifle or a more suitable firearm.
