In 2017, when the U.S. Army was phasing out the Beretta, everyone and their brother competed to win the Modular Handgun System contract.

Of course, that contract went to Sig Sauer, but that didn’t stop other manufacturers from releasing their entries – including FN.

The M17 is a formidable weapon designed to operate in the military theater
The M17, produced by Sig Sauer, was chosen by the U.S. Army as the replacement for the M9.

The 509 Tactical was FN’s submission for the MHS, but now it’s available in the civilian world for normal, everyday gun owners.

FN has a myriad of 509 models, but the Tactical means it has all the bells and whistles.

Who Is It For?

The 509 Tactical is a striker-fired pistol that’s best for those looking for a full-sized pistol with some elevated features. It also works great for left-handed shooters as its controls are ambidextrous.

If you need a bedside gun, I highly recommend the 509 Tactical.

Fit & Feel

This is not a small gun by any means. Being a full-sized, duty pistol means it’s large and not something you probably want to conceal appendix style. But that’s not really what it was designed for.

FN 509 Tactical Shooting

All the controls feel familiar, and this gun just makes sense in your hand. That FN grip feels good. Of course, you can change the backstraps, but whichever you choose, it will feel good in your hands.

But you lefties have already spotted something, haven’t you? The 509 series is completely ambidextrous right out of the box.

We like ambi

Nothing has to be swapped over – it’s ready to go.

That may not seem like a big deal to righties, but the lefties in the crowd can attest that this is a BIG deal.

Very few guns on the market are truly ambi. Not bad, FN, not bad…lefties are people too.

As far as aesthetics, I think it looks solid. I got FDE, but it’s available in black, of course. There’s some branding on the grip and slide, but nothing obnoxious.

Overall, it’s not a bad-looking gun.

How Does the FN 509 Tactical Shoot?

Before we start, I think it’s worth mentioning that this is my personal gun that I bought with my own money.

For this test, I got all the mags together. Loaded them with Remington UMC and let ‘er rip.

FN 509 Tactical Magazines
All the mags!

I was immediately struck with the trigger. It, of course, feels pretty stout. But it’s a duty gun, so that’s to be expected. That said, the reset is shallow, and on day one, I was able to get it running great.

Not sure how to explain it in words, but the trigger is really good for a service weapon.

FN 509 Tactical Shooting

As far as how it ran…well, it ran awesome for me — zero issues, like, for real zero.

Keep in mind I was using factory mags, and I didn’t run it suppressed or in weird weather, just summertime in Tennessee. But boy, oh boy, it kept up with me and ran without failure.

It feeds and ejects without issues and locks back on empty every time.

Locks back and everything.

I love the reliability. I have two FNs now, and they run like Belgian Sewing Machines.

Accuracy-wise, it stayed on target with no stray shots. It hit where I wanted it to without complaints.

The Trijicon 3-Dot Night Sights offer more than standard sights when sticking with traditional iron sights – even when shooting suppressed.

These sights are suppressor height, so you can still see your target even with a can.

But again, you don’t have to stay with regular, ole sights. The Tactical model means you get what you need to mount up a red dot. I added a Trijicon RMR to mine, and I really like the combo.

That Trijicon RMR worked great!

The only trouble I had was that I nicked my hand pretty badly on the range. Was that the gun’s fault? Nah.

Truth be told, I was sloppy with my grip, which is totally on me. However, those of you with big mitts, be aware.

What Sets It Apart?

Its ability to be range ready and lefty-ready out of the box is a huge win for the FN 509 Tactical.

All the features…

Want to mount an optic? You can do that. Need a light? It’s ready for one of those too.

Not to mention, the ability to upgrade mags from 17-rounders to 24 makes range reloads so much easier.

By the Numbers

Reliability: 5/5

This thing didn’t quit on me a single time. It just kept pinging targets.

Ergonomics: 5/5

It feels great in the hand, and the fact that it supports left-handed shooters is a bonus.

Accuracy: 5/5

It pings targets exactly where you want. No issues here.

Customization: 4/5

You can throw on a red dot, suppressor, or light, and those 24-round mags are great. That said, it doesn’t have the full suite of aftermarket as Glock (but really, who does).

Value: 3.5/5

It’s not cheap…at $900, it’s almost $300 more than a standard 509. Plus, you need to buy more mags. But for that price, you get what I think is a total package.

Overall: 4.5/5

    Ummmm, all the pics with the RMR mounted above are missing the included adapter plate.

    Upgrade with an apex trigger, then add a shooting sight striker to get rid of the rolling break, good setup after that, underrated option.

    If one tricks the pistol out to around $2,500, I certainly hope it would be a pleasure to shoot.

    2 things that will make this gun better, Apex and MCARBO. DARA makes a good holster to fit it even if you end up with all the furniture.

    The pistol with a suppressor and a light looks like a joke

    I think these got a really bad reputation for bad triggers. I've shot mine with a thousand rounds now and it is a great duty quality trigger. I also polished a few things and it's smooth no grit like it came with from the factory. I haven't had one FTF yet. I've shot with steel casin so much it wore off the fde on the slide from the steel shells coming out. I'd love it more if magazines weren't so expensive and there was a little more for holsters. Other than that it's one of my favorites. I also don't think that it's to expensive for everything you get from factory. 3 magazine, 2 of which are 24 rounders, the sights are amazing, threaded barrel, ambidextrous from factory. I actually think this gun is a good deal for what most people will spend on a cheaper gun to get to this point. Ask how I know. I also think the trigger is a great duty trigger but not amazing just for going to the range wanting the best trigger you can get.

      The trigger is absolute trash, even after a MCarbo trigger kit. The Walther PDP is a couple hundred dollars less and has a superior trigger. FN products are over-priced.

    I love lots of different platforms. This one just seems short of the vanilla G17. Where is the improvements? And not even close to aftermarket support of a G. Looks solid but the WHY? is where it looses me.
