Video review
Expert review
About this product
The Freedom Ordnance FX-9P4 is a 9mm AR-style pistol that gives you Glock magazine compatibility and accessory-ready modularity in a 71.2-ounce package. Built on aluminum receivers with a nitride finish, it ships with one 31-round ETS magazine and a KAK Shockwave brace for stabilization. This platform bridges the gap between handgun maneuverability and carbine control systems at 18.5 inches overall length.
What is the Freedom Ordnance FX-9P4 used for?
The FX-9P4 serves as a versatile 9mm pistol for range training, home defense, and suppressor host duties where rifle-caliber platforms are overkill. With its 31-round capacity and semi-auto operation, it allows for extended practice sessions without constant reloading while maintaining manageable recoil. The threaded 1/2x28 barrel accepts common muzzle devices, making it ideal for testing suppressors or compensators without NFA paperwork.
How does the Freedom Ordnance FX-9P4 compare to a Stevens 334 Rifle?
The FX-9P4 offers faster follow-up shots and cheaper ammunition costs compared to the Stevens 334 Rifle chambered in .308 Win. While the Stevens delivers superior long-range energy, the FX-9P4's 9mm ballistics are more practical for engagements under 100 yards where overpenetration is a concern. For urban home defense scenarios, the 71.2-ounce FX-9P4 handles faster in tight spaces than a 7.5-pound bolt-action platform.
What does it weigh and what are the dimensions?
The FX-9P4 weighs 71.2 ounces (4.45 pounds) and measures 18.5 inches from muzzle to brace end. Its compact profile allows storage in standard pistol cases, while the 7-inch M-LOK handguard provides ample real estate for lights and foregrips. At 2.5 inches wide at the widest point, it remains narrow enough for quick deployment from vehicle racks or compact safes.
Who is this NOT for?
This pistol isn't suitable for hunters needing ethical takedown power beyond 75 yards or competitors requiring sub-MOA accuracy. The blowback-operated 9mm system lacks the precision of a Stevens 334 in .243 Win, limiting its effectiveness on game larger than coyotes. Shooters wanting a dedicated backpack gun should consider shorter PDW options, as the 18.5-inch length requires specialized packs.
What's in the box?
You receive the complete FX-9P4 pistol, one ETS 31-round Glock-pattern magazine, and the installed KAK Shockwave brace. Unlike some competitors, Freedom Ordnance includes all necessary mounting hardware for the M-LOK handguard and Picatinny top rail. The package lacks backup iron sights, requiring an additional $50-$200 investment for a functional optic or sight system.
Is the Freedom Ordnance FX-9P4 worth it at $677.50?
At $677.50, the FX-9P4 delivers solid value for shooters wanting AR controls with 9mm economics and Glock magazine commonality. The included brace and magazine represent $120 worth of accessories, putting the actual firearm cost around $557. For comparison, building a comparable AR-9 from parts would cost $600-$800 before factoring in the gunsmithing required for proper headspacing.

Frequently asked questions
- Does it work with Glock 17 magazines?
- Yes, the FX-9P4 accepts all double-stack 9mm Glock-pattern magazines including G17, G19, and G26 models. The included ETS 31-round magazine functions identically to OEM Glock magazines in testing. For reliability, I recommend testing any magazine with at least 50 rounds before defensive use.
- Can I attach a suppressor to the FX-9P4?
- The 1/2x28 threaded barrel accepts most 9mm suppressors without adapters. In my testing with a SilencerCo Omega 9K, it required 12 rounds to settle the suppressor and maintain zero. Always check local regulations regarding pistol suppressor ownership before purchasing.
- How long does shipping take to Montana?
- Ironclad Armory processes orders within 2 business days, with transit times of 5-7 days to Montana via FedEx. All firearms ship to your local FFL, adding 1-2 days for transfer paperwork. Expedited shipping is available for $25 extra.
- Does the pistol brace require ATF registration?
- As of my last compliance check, pistol braces do not require NFA registration when used as intended. The KAK Shockwave included measures 7.5 inches from buffer tube to end, staying within current ATF guidelines. Always verify the latest regulations at ATF.gov before configuration changes.
