Grip texture on the FNS starts getting to me after 6 or 7 magazines. Only other gripe I have on mine is the take down lever pin gets warms obviously but it’s where my index finger sits when I’m in between shots. Looks like I might change over to the 509. I do like my 17+1 though.

I like this. Never owned an FN but this one peaks my interest.

Love my FNS9!!!  Best pistol I own.  I thought it was similar in size to the Glock 19, except for the grip.  Dimensionally the FNS and 509 are pretty much the same I think.  A lot of the changes appear to be cosmetic. Not sure why the mag capacity dropped to 15, though.

I'd like to pick up a FNS 9C at some point.  That might actually be my new carry piece, if I do.

FN's were my favorite, until I saw the inconsistency in accuracy among units. You could have two of the same exact model, and one would drive tacks, the other would look like you were patterning a shotgun. You never knew what you were getting.

I've owned three. One was dead accurate. The others, not so much.

Stick to CZs and PPQs. lol

I was happy to see they now offer the 509T in black. Would be nice to get my FNX45T a little bro.

I imagine like any production gun, luck of the draw applies. Happy to say my FNX is a tack driver with a surprising good trigger.

I imagine the gun is the one getting the short end of the stick when it comes to the accuracy equation 😁 (I know this is true when I'm behind the trigger)

I feel that pain all to many days. I dont feel particularly cross-eyed at the time, but the target begs to differ !

 I just sold my FNS which was great but the trigger was 7.5 lbs,too stiff for me and this one also is 7.5#s..Deal killer for me.

CZs are under 400 bucks now,I find them to be top of the food chain so Ill stick with them for a while,3.5# triggers too

I own an FNP45, FNX9 and an FNS9c. All are more accurate than I am. I was surprised how well I shot the compact. It goes with me everywhere in an IWB holster. I did however just get a Sig p365 for pocket carry for times that I don't carry IWB for some reason. Haven't shot it yet but like the size. Love my FN pistols. Coveting the FNS 509 tactical at the moment.

Think I have too may 9mm pistols already, so probably wont go after this one.  I do love my FNP-45USG though.  Shoots anything i put in it, and way better than I do.  Even likes that cheap Russian ammo, lol.  As I age, though, I find that my fat body just doesnt carry the extra weight these days...New daily carry is my Sig P-365 and the S&W Bodyguard .380.  I can carry both of these  easier than I carried the FN with extra mags...

 Initial thoughts:

▪️Grip texturing is great! I like how they used different textures for different parts of the grip. It's as if they spent some time thinking about it rather than just smearing the same texture all over. 😉

▪️It really is the same size as Glock 19 or an M&P M2.0 9mm Compact and, for me, that is a good thing. With the larger of the two backstraps installed, as it came from the factory, the grip profile has a soft curve that a cover garment should drape across more gracefully and not be as "identifiable" as is with a Glock 19.

▪️The mag release on the 509M is easy to manipulate but not so easy that it could happen accidentally.

▪️Deep undercut on the trigger guard allows you to get a good, high grip on it. The polymer there has a super-fine texture that shouldn't agitate anyone but I may polish it to a mirror at some point. I prefer an undercut that is as smooth as glass.

▪️The stock sights are steel, which is good, but I prefer a very prominent front dot and no, or subdued, rear dots with a U-notch. I have a set of Trijicon HD sights on the way.

▪️The barrel is crowned, which is nice to see. I also noticed that the final half-inch (approximate) of the barrel right before the muzzle is a thousandth of an inch or so larger in circumference than the rest of the barrel's length. I assume this aids in accuracy much the way a bull-barrel in a 1911 does by providing a snug fit between the barrel's terminus and the portal that it passes through in the end of the slide.

▪️The slide release lever is a piece of cake to manipulate with either hand, unlike the M&P M2.0. The extractor is a monster and looks hella stout. The slide serrations, fore and aft, are perfect and exactly what I prefer on a fighting gun.

▪️The trigger is NOT BAD AT ALL! It's a bit heavy but seems to be lightening up and smoothing out a little as I dry fire it. I'll put a trigger gauge on it tomorrow. Wish I'd done that before dry firing it a hundred or so times, for comparison. Whoopsie.

I doubt seriously that I will swap the trigger out for an Apex part. The OEM trigger seems just fine for me.

      I wasn't planning on picking up a new gun "BUT" Walther just came out with the new Walther PPQ Q5 Match Steel Frame.  I sold my polymer PPQ and picked up the new steel frame.  It has been a long time since I really got excited about a new gun but I really like this gun.  It is a heavy gun at 2lbs 10oz with an empty magazine so it will be legal for SSP/ESP division in IDPA.  My main purpose for the gun is to shoot Carry Optics division and the weight limit is 45oz with an optic.  The optic I will use will be the C-more RTS2 6 MOA.  The gun does come with three mounting plates, not for the C-more.  Had to purchase one from C-more.  The grip is a little bit more aggressive than the polymer gun and I am very happy with that.  I hope to get out to the range soon and when I do I will do a range report.

      For 2019, Ruger has decided to cease production of the SR family of striker fired pistols.  

      Personally, I think they made a big mistake.  I guess they wanted to push the American but I think the SR would have done better if they released it in a "pro" model without the safety.
