Freedom Ordnance FX-9 9mm AR Pistol

Freedom Ordnance FX-9 with Red Dot on Table

There’s no shortage of AR-15 rifles, pistols, manufacturers, and models, but one that stands out in both value and features is the Freedom Ordnance FX-9. This AR pistol chambered in 9mm Luger provides a lot of bang for the buck — pun intended! Freedom Ordnance, a firearms manufacturer in Indiana, has developed a good reputation for making 9mm AR rifles and pistols. Additionally, Freedom Ordnance is no stranger to the Second Amendment, with “Shall not be infringed” stated as the core belief of the company’s mission.

FX-9 AR Pistol Features

With so many ARs on the market, it can be hard for a single model to stand out. The Freedom Ordnance FX-9 is constructed out of billet aluminum alloy receivers and is compatible with most standard AR parts and accessories. Further, steel components (such as the barrel, bolt, ejector, last round hold-open, feed ramp, and extractor) are nitride coated for extended wear properties and corrosion resistance.

The FX-9 features an ambidextrous safety selector, which, being left-handed, I was happy to see. Even before firing, I had issues with the ambi safety lever (side for left-hand use) coming loose and falling off the firearm. This was simply an issue with the set screw coming loose and needing a bit of thread lock.

The free-float rail helps improve accuracy and barrel cooling, and M-Lok slots allow you to attach lights, lasers, and grips. The magwell has been designed for Glock-style magazines and is not just converted from a standard AR lower. From the factory, the FX-9 comes with either a Shockwave Blade pistol brace or a padded buffer tube with a sling attachment.

I swapped the brace out for the SBA4 from SB Tactical because I prefer this style. I also swapped out the muzzle device to a Yankee Hill mount for suppressor use. Both originals would work well if you wanted to keep the firearm as is, but personalizing is half the fun of the AR platform.

Accuracy and Reliability

At the range, the Freedom Ordnance FX-9 was a blast to shoot. Accuracy was what I expected, not high-end rifle level, but perfectly suitable for what it’s designed for. I didn’t test it out to 100 yards. However, for closer engagements, it worked well. Definitely more accurate than using a standard 9mm pistol. A 9mm AR pistol produces basically no recoil, so follow-up shots were a breeze. A good pistol brace works wonders.

Freedom Ordnance advises against using aluminum-cased ammunition. Not an issue for me, but it’s worth noting. I test-fired 100 rounds of 147-grain Federal American Eagle as well as a couple of boxes of 115-grain Winchester white box. Reliability was good, with only one failure to eject from the American Eagle. The spent casing got stuck sideways in the chamber, and I had to use the pick on my Leatherman MUT to remove it. Aside from that, it was smooth sailing.

Swampfox Red Dot Sight

For testing, I mounted a Swampfox Liberator red dot sight to the FX-9. This is a lightweight and compact option that pairs well with these smaller AR pistols. The version I selected features green illumination with a circle dot reticle (2 MOA dot for precision paired with a 65 MOA circle to catch your eye). Adjustable brightness settings allow you to optimize the optic for your lighting environment.

The Swampfox Liberator runs on a CR2032 battery for up to 3,000 hours of runtime on the medium brightness setting. After four hours of inactivity, it will shut off automatically. Simply press one of the brightness adjustment buttons to turn it on again.

The Liberator features multi-coated lenses to reduce glare and is fog-resistant, shockproof, and waterproof. Overall, Swampfox makes an accurate and durable optic.

Why an AR-9 Pistol?

With so many firearms on the market, why would you choose an AR-9 pistol? A 9mm AR pistol is a compact alternative to a rifle or carbine. It’s more maneuverable in tight quarters, while still providing three points of contact (both hands and shoulder). This allows you to shoot faster and more accurately.

Having your AR pistol chambered in 9mm Luger has the added benefit of producing less recoil than a rifle caliber. Though it will not be as powerful as a rifle caliber, it’s quieter, lighter weight, and produces less muzzle blast. If you build your system right, an AR pistol offers magazine compatibility to your sidearm. Additionally, this can help reduce the number of different calibers of ammunition you need to stockpile.

Conclusion: Freedom Ordnance FX-9

Shooters looking for a quality AR pistol in 9mm would be hard-pressed to find a better deal than the Freedom Ordnance FX-9. With quality features at an excellent price point, the FX-9 flat-out delivers. Having a good 9mm AR pistol provides you with a compact alternative to a full-size rifle that has a little more versatility than a handgun. If you haven’t tried one out, it should definitely be on your to-do list.

  1. I have this one in my cart as we speak. Yet t pull the trigger. Great price too. But with 3 dozen other firearms, I’m not sure I really need this one. As I get older I have been naturally looking for easier, lighter, and more convenient firearms for home defense, varmints, and ones I can pack away easily in my truck. I just sold two of my comparable firearms cuz I was going to widdle down my collection a little, but I think I went the wrong direction. I need to start selling all those big bores! (460, 44s, 45s, etc.) I’ll keep my 357s all day long.

  2. I recently purchased a fx-9 8 inch barrel freedom ordnance pistol and would really like to know the year it was manufactured. How do I determine this. I really love this pistol and have noticed on the web site that it helps to have this info. for various reasons. Thanks very much!

  3. Love my FX-9!! Smooth as butter and fun to shot. I can fill a target full of head shots at 25 yards with a decent red dot, pretty good at 50 yards too. I

  4. I purchased one of their FX-9 carbines (16″ BBL) back in 2019 and I love it. Of course back then I got it for $579.99 but now I see they are selling for $753.42. Inflation I guess…

  5. I purchased my fx-9 for about 2 years ago. It is a GREAT firearm! While I have not had any issues with the ambi safety switch, I agree with the author and can’t add anything else. Well, maybe I could say, buy one for yourself. I don’t think you will be disappointed.

  6. I’ve enjoyed shooting a buddy’s CMMG Banshee and Ruger PC9 enough to look into buying my own PCC, but I’m a Sig fanboy and there are limited cost effective options taking P320 mags! Hope manufacturers get on board in the near future so I can enjoy mag interchangeability.
