Been a while since I have posted on this board. I do have a FNP 40 & 45 so I am very familiar with the FN series of pistols. Had been considering the FNS or the Sig P320 compact, but when I handled both at my LGS today, the FNS just seemed to fit the hand and even the arthritic trigger finger felt at home with the trigger system. Since the only model in stock had plain sights, they are tracking down one with NS and a thumb safety. I know a lot of folks don't like a thumb safety these days, but for years I carried a 1911 and feel at home with them. Also, it is there to use or not use as well. Will follow up later when I bring it home and put a few hundred rounds through it.
I got one with night sights and the safety. P320's trigger felt really gritty to me--which was a real surprise, given how much people have raved about it.
I'm fairly new to pistol shooting, but I have an HK VP9, Glock 30, and M&P Shield. I was really intrigued by the FNS-9c when I saw its specs. After getting it, I have to say that it's a phenomenal pistol. For a carry gun, I think the trigger is spot on. Ergos are great too. Most noticeable is the really aggressive grip texture, which I think is a huge plus. (I have to put talon grips on my others.) I have 300-400 rounds through mine. Not one hiccup.
The only downside, as far as I can tell, is that magazines aren't yet available.... Per my e-mail to FN customer service last week, they're supposed to become available at the end of this month....
