FN makes a ton of small arms for the United States military. I carried an FN-produced M16A4 and M240 as a Marine, and FN’s firearms dominate military armories. It wasn’t a big surprise to see that FN decided to toss an entry in the Army’s modular handgun contest. FN didn’t win, but we did, and FN made the wise move to make the FN 509 their flagship handgun.
The Army didn’t choose the FN 509, but it didn’t get abandoned entirely. Brinks, the armored car company, selected the FN 509. Recently, the LAPD also chose the 509. It’s not without a home by any means.
What exactly is the FN 509? Well, it’s a striker-fired, polymer-frame pistol chambered in 9×19. Predictably, it uses a double-stack magazine and gives users a capacity of 17 rounds in a flush-fitting magazine. Various capacity magazines exist, including California-approved 10 rounders and tactical 24 rounders.
The FN 509 proved popular enough and evolved over time to produce various models.
I’d imagine the gun’s overall design was made to be modular and easy to switch up on the fly. It might not have the FCU of the P320, but that doesn’t mean you only get one flavor of FN 509. FN’s done a fantastic job of producing various models at various price points
This includes compact, tactical, and now the FN LS Edge variants. LS stands for Long Slide, and the barrel length reaches 5 inches. Edge can stand for bleeding edge, which is an accurate way to describe the weapon. Sure, we get the long slide, but we get so much more than that.
The LS Edge comes optic ready, with the fancy two-tone finish, and it comes with a variety of favorable features found on modern handguns. FN took the 509 series to the moon with the LS Edge. The design pushes the pistol away from concealed carry and more towards the competitive market.
Although, the idea that the LS Edge couldn’t be used for home defense or duty is silly. Neither of those duties has a concealment need. It’s a big gun, and if you like big guns, the LS Edge might be a rock-solid go-to for a variety of roles.

FN LS Edge Review – Our Take
The LS Edge comes with an optics mounting system that mixes a variety of plates and screws and more to allow you to mount all your favorite handgun optics. Dozens of pistol optics are covered. FN takes optics ready to a new level with the addition of actual suppressor height iron sights. Why suppressor height sights aren’t standard on all supposed “optics ready” handguns is beyond me.
The included iron sights are all kinds of sweet and perfect for this pistol. Our front sight packs a high visibility green insert that’s quick for the eyes to see and well suited for long-range accuracy. A big benefit of a long slide is a longer sight radius, which makes the weapon easier to shoot accurately.
A thin front sight makes it easy to see a target at longer ranges. The all-black rear sights offer awesome contrast to the high vis front sight. Those tall rear sights are also protected by a set of metal ‘wings’ that allow the weapon to be racked on a belt, table, or whatever without damaging the tall rear sights.
FN packed the gun with a flat-faced trigger that breaks cleanly at 90 degrees. It’s a light and short trigger pull with a little take-up then a solid little break. A good trigger combined with good sights and a long sight radius makes the weapon very easy to shoot accurately. Oh, and I forgot to mention that the barrel is a target-crowned, hammer-forged barrel.
At 50 yards, I had more dings than not on a steel gong. Within 25 yards, it felt like it was harder to miss than hit. Putting round between a Fred 3D’s eyes wasn’t a challenge at 7, 10, or 15 yards by any means. Neither was hitting eight playing cards in 7 seconds, at ten yards.
That long slide the LS Edge packs helps with some recoil and muzzle rise. FN used several strategic cuts to lighten the slide. A lighter slide reduced felt recoil by reducing the reciprocating mass of the slide. Those slide cuts also help better balance the gun. A lot of long slide firearms feel front-heavy, but the LS Edge feels remarkably balanced. Recoil is very controllable, and the gun’s full size, aggressively textured grip certainly helps.
The grip comes with interchangeable palm swells to fit the grip to your hand. A small beavertail allows for a high grip, but the trigger guard keeps you from getting any higher. I don’t see a lot of room to thin it out for a better undercut, either.
FN graced the pistol with a few awesome ergonomic upgrades. A set of oversized, ambidextrous slide stops are nice. The magazine release is massive and textured, and when that’s paired with the integrated magwell, your reloads can be quite fast.
I rather enjoyed the intuitive and rapid reload. Sometimes features help boost your confidence in the weapon, and I felt that way running reload drills. The mag went where I wanted it, right when I wanted it to.
I typically prefer a wide variety of ammunition to test reliability. Times being what they’ve been, limited me to several hundred 115 and 147-grain brass-cased FMJs, and 20 rounds of 124 SIG JHPs. The LS Edge took no issue with my ammo selection and blasted its way through over 400 rounds of ammo without issue. Heck, the mags even held up to sand exposure from so many reloads.
Shooting the FN 509 LS Edge is a breeze. It doesn’t buck with recoil, the sights are easy to use at any range, and the gun packs a wallop speed-wise. FN put a lot of thought into the gun, and it very clearly shows. The weapon’s remarkably balanced, reliable, accurate, and it’s a lot of fun to shoot. I felt so capable with the LS Edge I thought it’s not that big. I can totally conceal carry it.
With the Phlster Floodlight, it might just be possible.
LS Edge Pros and Cons
- Extremely Accurate
- Optics system is Low Profile
- Great Trigger
- Well Balanced
- Easy to track sights
- I would prefer an even higher grip
The LS Edge offers an awesome shooting experience free from the constraints of poor ergonomics. Recoil and muzzle rise is low, the gun’s grip is comfy, and it’s super easy to control. Tracking sights with the long slide is easy, and the gun is even well balanced.
The FN LS Edge ate everything without complaint. The gun worked well, even when the magazines ate a healthy amount of sand during reload drills. No complaints whatsoever.
It’s almost perfect. My main complaint is that I feel like a higher grip would be better for control purposes. Give me a bend and buck to that trigger guard, and let me get my hand nice and high.
Oh boy, hell yeah, this thing is accurate. It’s one of the most accurate pistols I’ve ever handled, and the combination of great sights, a long sight radius, a great trigger, and a match-grade barrel make it super easy to shoot.
Oh, boy, with an MSRP nearing $1,500 bucks, this is not a cheap gun. The price at most gun shops seems to be around 1,299ish, so still, not much better. That being the gun is featured filled and does offer you a top-notch experience.
