I received a FNS 9 as a Christmas present from my son in-law. This is their newer model with no manual safety.
Looks nice, but read lots of things in older reviews and youtube vids that were not too promising.
My son in-law has the FNX 45 and I didn’t like the way it shot or the very minimal way it ejected the empty shell cases, usually right in my face.
But....
I took it to the range a couple of days ago. I really wanted to wring it out. I cleaned it thoroughly then off to the range.
I mainly used Winchester 9mm Nato 124 grain hardball and Ranger T series 147 grain ammo, plus some older Remington 115 JHP.
All together I fired 700 rounds through the gun, 10 round mags at a time. (Yea I know its Calislavia).
No cleanining, lube, or wiping down until done.
Feel
The sights and trigger were good for a striker fired pistol. The front sight dot is just a little bigger than the rear dots making it easier for my old eyes to see.
The FNS 9 comes with a straight and curved back strap. I first tried the curved then switched to the straight. I seemed to like that much better.
Magazine ejection was smooth and the mag well is beveled nicely. Fast reloads are positive. The checkering is aggressive.
If you thought the Glock was a blocky gun, well, so is this.
Shooting
No failures of any kind observed. Positive feed, function, ejection. Certainly nothing in my face like the FNX 45.
Accuracy was excellent at 15 yards. Even when the gun was filthy dirty it kept running with no issues.
Carry
The only issue I found, and it is not really much of an issue, is the grip checking is pretty sharp. Not shooting it in my rough hands, that I liked.
It was in the carrying of it for a couple of hours that I felt those sharp edges.
I have not found a holster for it yet so I carried Israeli style, full mag, nothing in the chamber, in my waistband. Since it was cold I had an undershirt on but still felt that checkering. If this had been summer, without a holster, no way against my bare skin.
A good IWB holster will help to some extent. But the grip is rough. I like it, I just have to watch it. YMMV
Overall I like it, it is a keeper. I am a die hard Glock guy, but this is a good gun IMHO. It rivals the Glock.
Now if I can just find a good IWB holster, night sights, and some 17 round mags.....
