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.
