Description
The Arex Rex Zero 1 T 9mm is a service-grade pistol designed for American shooters who value reliability over flash. Whether you’re looking for a dedicated home defense handgun, a durable range companion, or a suppressor-ready platform for training, this Slovenian-made firearm offers a proven, duty-tested foundation. Chambered in 9mm with a threaded barrel and 17-round capacity, it brings NATO-spec durability to your holster or nightstand.
What This Product Is and Who It’s For
The Arex Rex Zero 1 T is a full-size, hammer-fired semi-automatic pistol based on a robust, all-metal design. It is built for shooters who prioritize consistent trigger pull, corrosion resistance, and ease of maintenance. This model is well-suited for target shooters who want a reliable platform for high-volume range sessions, home defense users who prefer a manual safety and decocker, and collectors who appreciate the engineering behind a modern military contract handgun. It is not a lightweight concealed carry piece, but it can serve that role with the right holster and belt. The threaded barrel also makes it a strong option for those who plan to use a suppressor or compensator.

Feature Deep-Dive
Hammer-Fired Action with Decocker. The Arex Rex Zero 1 T uses a traditional double-action/single-action trigger system, similar to many service pistols used by military and law enforcement. The first shot can be fired in double-action (longer, heavier pull) or you can manually cock the hammer for a single-action shot. The frame-mounted decocker allows you to safely lower the hammer on a live chamber without pulling the trigger. This system gives you the choice of a consistent single-action trigger pull for accuracy or a heavier double-action pull for added safety in a high-stress situation. The trigger break is clean, with a short reset that aids follow-up shots.
Threaded Barrel for Suppressor Use. The factory threaded barrel (1/2×28 TPI) is a significant feature for shooters who want to run a suppressor or compensator. The barrel is cold hammer-forged from stainless steel, then nitrided for surface hardness and corrosion resistance. The included thread protector is low-profile and flush-fitting. This allows you to attach most 9mm suppressors without additional adapters. The barrel extends slightly past the slide, providing a longer sight radius and improved ballistics with certain ammunition types. The threads are cut to standard U.S. specifications, so aftermarket muzzle devices are widely available.
All-Metal Construction with Modern Coatings. Unlike many polymer-framed competitors, the Arex Rex Zero 1 T uses a machined aluminum alloy frame and a stainless steel slide. This gives the pistol a solid, balanced feel that reduces perceived recoil and improves muzzle control. The frame is hard anodized, and the slide uses a black nitride finish. Both coatings are highly resistant to sweat, moisture, and holster wear. The steel barrel is also nitrided inside and out, which helps extend service life and simplifies cleaning. This level of corrosion protection is especially beneficial for shooters in humid climates or those who carry the pistol in a sweat-prone area.
Ambidextrous Controls. The pistol is designed for both right- and left-handed shooters. The manual safety is ambidextrous, as is the magazine release. The slide stop is also accessible from either side, though it is not fully ambi. The decocker is located on the frame behind the trigger guard and is easily reached with the thumb of either hand. This makes the pistol suitable for shooters who train with support-hand manipulation or who need to hand the firearm to a partner. The magazine well is slightly beveled to speed reloads, and the steel magazines drop free consistently.
Sight System and Accessory Rail. The fixed 3-dot steel sights are dovetailed into the slide, allowing for windage adjustment or replacement with aftermarket options. The front sight is a standard width and height, and the rear sight has a serrated face to reduce glare. The front of the frame includes a Picatinny-style accessory rail (one slot) for mounting lights or lasers. While a single slot limits some full-size weapon lights, it is sufficient for compact lights or laser/light combos. The rail is machined into the frame, not attached, so it will not loosen over time.
Magazine Design and Capacity. The pistol ships with two 17-round steel magazines. They are double-stack with a single-feed follower, which aids reliable feeding with a wide range of bullet profiles. The magazine base pads are flush-fitting but have a slight lip to assist with removal. The magazines are compatible with aftermarket extensions, though 17 rounds is already a standard capacity for a full-size 9mm. The magazine catch engages a hardened steel insert in the magazine body, so it will not wear out quickly. Spare magazines are available from Arex and several third-party manufacturers.
Ideal Use Cases
- Home Defense: The full-size frame, high capacity, and threaded barrel for a suppressor make this a strong choice for a nightstand or safe. The manual safety and decocker give you multiple layers of safe handling.
- Range Training: The SA/DA trigger system allows you to practice both trigger types in one session. The all-metal construction absorbs recoil, making it comfortable for extended range time. The fixed sights are durable and easy to acquire.
- Competition (USPSA, IDPA): While not a dedicated race gun, the 17-round capacity and threaded barrel (for a compensator) make it viable in Production or Carry Optics divisions. The trigger is serviceable out of the box, and the weight helps with recoil management.
- Suppressor Host: The factory threaded barrel and tall enough sights (though not suppressor-height) allow you to mount a suppressor without needing a booster if you use a fixed barrel mount. The slide is robust enough to handle the added back pressure.
Compatibility Notes
- Ammunition: This pistol is designed for 9mm NATO pressure ammunition (124 grain or 115 grain). It will function with standard pressure and +P loads. Avoid +P+ ammunition, as it may accelerate wear on the barrel and recoil spring. Steel-case and aluminum-case ammunition is generally acceptable, though we recommend brass-case for reliability.
- Holsters: The Arex Rex Zero 1 T fits holsters designed for the standard Rex Zero 1 (non-T) with a threaded barrel. Many holster makers list specific models for the threaded barrel version. For IWB or OWB carry, look for holsters that accommodate a suppressor-height sight or threaded barrel. Leather and Kydex options are available from brands like Blackhawk, Safariland, and several custom shops.
- Magazines: The pistol uses proprietary 17-round steel magazines. Magazines from other brands (e.g., Beretta 92, CZ 75) are not compatible. Spare magazines are available directly from Arex or through distributors like MGB (MGB Imports).
- Accessories: The Picatinny rail accepts standard weapon lights and lasers. For suppressor use, you will need a 1/2×28 threaded suppressor. The fixed sights can be replaced with aftermarket options from companies like Dawson Precision or Trijicon (for suppressor-height sights, you may need to check compatibility with the slide profile).
- Threaded Barrel: The 1/2×28 thread pitch is the most common for 9mm suppressors in the U.S. You can also use a thread adapter for 1/2×28 to 5/8×24 if needed, though this is uncommon. The barrel is not designed for use with a silencer without a Nielsen device (piston) on a tilting-barrel pistol.
FAQ
Q1: Can you ship this firearm directly to my home?
No. Federal law requires that all handguns shipped to a U.S. buyer must be transferred through a Federal Firearms License (FFL) holder. We will ship the Arex Rex Zero 1 T to your chosen FFL dealer. You must provide their FFL information at checkout or after placing the order. We will not ship to a residential address.
Q2: How does the FFL transfer process work?
After you place the order, we will contact you to confirm the FFL dealer you want to use. The dealer must send us a copy of their FFL license (via email or fax). Once we verify the license, we ship the firearm. You then visit the dealer, fill out ATF Form 4473, and pass a background check (NICS). The dealer may charge a transfer fee, which is separate from our price. We ship within 1-3 business days after receiving the FFL.
Q3: What ammunition can I use with the threaded barrel?
The barrel is rated for standard pressure and +P 9mm ammunition. We recommend using 124 grain FMJ for range use and 124 grain jacketed hollow points (JHP) for defensive use. Avoid +P+ loads, as they can cause excessive wear. For suppressed shooting, use 147 grain subsonic ammunition to stay below the speed of sound. Always check your local laws regarding suppressor use and registration.
Q4: What is the warranty coverage?
Arex Firearms offers a limited lifetime warranty to the original owner. It covers defects in materials and workmanship for the life of the firearm. The warranty does not cover normal wear, misuse, or modifications. If you encounter an issue, contact our customer service team, and we will help you file a warranty claim with Arex. We also offer a 30-day return policy for defective items (
