Arex Rex Zero 1 Pistol — The New Kid on the Block

Arex Rex Zero 1 Pistol

Just the name, Arex Rex, conjures images of something prehistoric and capable of stomping you between its toes just to be more merciful than swallowing you whole. However, the new Arex Rex Zero 1 is anything but prehistoric. That being said, if it looks a bit familiar to you, you are not alone.

Arex Rex Zero 1 Pistol
The Arex Rex Zero will be offered in three sizes and four calibers.

Place the Rex Zero 1 next to a SIG P Series such as the P226, and there is more than just a similarity. However, once you get into the details, that’s where the comparison ends. Well, maybe. While similar, up close the dimensions are certainly different. The same is true when you compare a list of features.

The Arex Rex Zero is offered in three sizes and four calibers. The Rex Zero 1 Standard is a duty-size gun featuring a 4¼-inch barrel. Chambered in 9mm, the Standard model is fed by a generous 17-round magazine for a total weight of 28 ounces.

Like the SIG P226, the Arex Rex Zero comes standard with a decocker. However, unlike the SIG, the Arex’s decocker serves double duty. When depressed, it safely lowers the hammer. When pressed upward, it serves as the slide stop.

To the rear of the decocker is an ambidextrous safety. The Arex can easily and safely be carried cocked and locked or DA/SA, depending on the user’s preference. Fieldstripping is also easy. Simply lock the slide back with the slide stop, rotate the disassembly downward, and slowly disengage the slide stop while controlling the slide as it goes forward. From there, the spring and barrel easily slip free.


Thus far, the Arex has not proven to be that different from many models, but it has incorporated many of the most sought-after features. The frame is machined from hard-anodized aluminum using solid bar stock and a steel locking block insert—it just doesn’t get stronger than that. The slide is machined from nitrocarburized steel, which is touted as having a greater resistance to corrosion.

The barrel is cold-hammer forged and nitrocarburized from—you guessed it—solid bar stock. Test models were made available with threaded barrels at the SHOT Show earlier this year. However, there are no details as to their price or availability at this time.


The Arex Rex comes with a standard steel 3-dot sight, which is a plus. The rear sight is substantial enough that you should be able to use it as a battle sight and manipulate the slide using one hand and a belt, pocket, vest, etc. Sights are personal and not one size fits all, but these worked great for me. However, if your preferences differ, word has it that SIG sights as well as any aftermarket sight for the SIG will fit.

The Arex Rex Zero 1 has an ample-size rail machined on the front to hang your favorite laser or light. It also comes with two magazines, a small cleaning kit and a hard plastic case.

As previously mentioned, the Arex Rex Zero comes in multiple sizes. It is (or will soon be) (which is it?__KD) available in multiple colors as well. In addition to the Standard, the Arex offers a Combat and Complex model.

Arex Rex Zero 1 Combat

The Arex Zero 1 Combat tapes out a bit shorter than the Standard and is slightly shorter with a 3.85-inch barrel. It also weighs a bit less at 27½ ounces. Despite these differences, the grip and magazine capacity are the same.

Arex Rex Zero 1 Compact

The Compact keeps the same 3.85-inch barrel as the Combat but features a shorter grip that accounts for the loss of two rounds. However, 15 rounds from a Compact model is still a helluva payload. At 5.3 inches, the Compact is about .4 inch shorter than its two big brothers and tips the scales at 25 ounces unloaded.

The Arex Rex will be offered in three frame colors—flat dark earth, foliage green and graphite black. However, the early guns will all be black.

Available Calibers

The Rex in 9×19 will most likely top the charts, but it will also be available in 9×21, .40 S&W, and .32 ACP.

The Arex Rex is made in Slovenia, which will be a turn-off for some and a concern for others. You can rest easy knowing Arex is not a newcomer; it has been around for decades as a tool manufacturer. It is now expanding it offerings to include its first foray into the firearms market with a solid contender.

Arex pistols are being imported by the FIME Group in Nevada. It will also provide full warranty support, so should any troubles arise, you will have a local source for repairs. The Rex comes with a limited lifetime warranty.

  • Forward cocking serrations
  • Loaded-chamber indicator

  1. So this is basically a nicer finished Zastava with a manual safety at twice the price?
    Got to admit I really like the looks of it.
    I own a Zastava ez9 compact and even thought the finish is not as nice as the rex it has still been !00% reliable through hundreds of rounds.

  2. I picked up my ReX a couple weeks ago after watching several YouTube reviews including Military Arms channel 1,000 round test. I have to say the quality fit and finish of this pistol is typically well above the $600 MSRP price tag. I do think the grip feels large and I have fairly large hands. The DA feels like it comes in at a pretty heavy 11 or 12 lbs, but the SA is really nice and felt like a touch under 5lbs IMO. Whatever nitriding/hardening process is being used by the manufacturer is top notch. I’m truly impressed with the quality of this pistol. Hoping to see some grip options in the future.

  3. A great price for a full size full metal hammer pistol, payed same amount as an M&P 9, near new. While it has cool features like safety and ambidextrous mag release/safety, has some not se great characteristics that no one has mentioned. Being left handed, was happy to find a pistol with ambidextrous features, except not where it counts. The slide release is the deckocker which is not ambi and makes it impossible to release slide after mag change without altering grip and moving off target, the lever is extremely stiff as well. Next the grip is Huge I think it’s larger than an FNX 45 grip. Shooting is comfortable but operating the mag release is not with such huge grips. The grip material is also hollow plastic and not very sturdy, very cheap and brittle feeling to it like a toy. If I could change one feature then i would have the slide release automatically when a loaded mag is inserted. Overall a good shooter for 1/2 the sig price.

    1. Thanks for the honest user review, I’ve wanted to hear one as I’m intrigued by this pistol. I have a Legion and TACOPS P226, and like where the slide release is on the Arex design. If you like the idea of the slide automatically closing when a mag is inserted, then you should look into Grand Power pistols (from neighboring Slovakia). They have that, among other unique features, designed in as features.

  4. I visited the factory in Slovenia where these pistols are made and was given a personal tour by the owner, who by the way is a very nice fellow…I was really impressed with their facilities. The detail to make a quality handgun was noticeable from beginning to end…I also had the chance to shoot the full size version at their very nice range and was very pleased with the accuracy and the ergonomics…I hope they are successful in their quest to enter the US market….

  5. Looks interesting. What I especially like is that the slide stop appears forward enough that is old 1911/high-thumbs-forward grip folks can shoot and have the pistol lock back after the last round. I bought a Legion 226 because of this very issue, since slide stop is ground down to a tiny nub but is still in the “wrong” position.

    What would really be an awesome feature is if these guns accepted all my Mec-Gar 226 and 229 mags.

  6. It looks pretty nice but why not offer a threaded barrel. A threaded barrel should come standard on a few of the select models especially this day and age where they’re becoming more common.

  7. Actually, I do believe that Bond already had his 32 ACP and many wounds to prove it, which is why I M forced him to move up to the 380 ACP.

    Somebody else double-check me would you?

    1. And, after forcing the .380 on Bond, Bond attempted to walk out of M’s office with both and M caught Bond in the act.

    2. Actually, I believe the PPK that M forced on Bond was in .32. His Beretta that it replaced was a tiny .25. At least, that’s how I remember the movie, “Dr. No.” Possibly the book was different.

    3. The Beretta Bond was using was “that damned .22”, according to the movie. What M replaces it with is indeed the PPK in 7.65 (.32).
      First Bond movie, and still one of the best.

    4. I am old enough to have actually read some of the Bond books way back when, and you are exactly right.

  8. The review includes physical description and features but not functional and practical performance.
    What to think?
    Without an idea of its functional and practical performance, -nothing.

  9. Looks like a gun worth checking out. I love how the Israelis developed the 9X21 to get around some of the more idiotic gun laws in Europe, such as Italy’s ban on 9 mm ownership by civilians.

  10. Walker – Thanx for the info on the next pistol being a .45 ACP. I look forward to seeing it – and then BUYING IT!

  11. Rex missed the boat on caliber selection. Who really wants a puny .32 pea shooter? Not I. I was really hoping for a .45 ACP offering. Last year I watched a video on the Arex build in Slovenia. Very professional state of the art manufacturing processes. I would not hesitate to purchase a Rex – in a .45ACP! I have all the 9mm’s I want, and see no need for a .40 cal. GIMME A .45ACP with a 4″ to 5″ barrel and a double stack mag… preferably with a suppressor-ready barrel.

    1. Rex DID NOT miss the boat in calibers. There are NO PLANS for those calibers. The next caliber will be .45 ACP…i do not know when but that is the next caliber. I know because I am the sales director for FIME (Exclusive importer for Arex) and I talk directly with the factory.

    2. Thanx for the good news on the .45ACP. I look forward to seeing it in action…and then BUYING ONE.

    3. Hey Walker,

      Just for informational purposes, good wrecks or you provide a clue as to why they went with a 32 ACP, instead of the much more accepted 380 ACP?

      The American Market is simply not going to accept a sidearm in 32 ACP, in any real numbers, so why build one?

      I understand the history in Europe of liking the 32 ACP, but even James Bond had to give his up in favor of a 380 ACP, because real world results clearly indicated to 32 ACP just could not get the job done.

      Thank you ahead of time for your time and effort in answering my query.

    4. JR…there are no plans for a 32. The next caliber will be a .45 ACP. Beyond that I can’t and won’t say except that I understand the American market very well and would will be shocked if we even talk about doing a 32. Thanks for your interest

    5. Hey again Walker,

      Ok, you can now color me ‘officiall corn-fused’!!!

      Here is what Dave Dolbee wrote in the paragraph under the rubrik “Available Calibers”:

      “Available Calibers

      The Rex in 9×19 will most likely top the charts, but it will also be available in 9×21, .40 S&W, and .32 ACP…”

      Please take note of that last caliber, which Dolbee says the pistol will be chambered in, “32 ACP.”

      This is where I came up with my serious concern about why the company would chamber a pistol for the American Market in 32 ACP, rather than the more ubiquitous 380 ACP.

      I would appreciate some clarification if possible please. Thank you.

    6. Believe what Walker says; he is the man. My article was based on older information. ~Dave Dolbee

    7. Please clarify. You said the .45ACP was the next up – and discounted the other calibers as being viable. NOW WE HEAR that the original statement about .32, 40cal, etc. was correct…sooooo – when is the .45ACP really coming to market (if at all)?

    8. Right you are, Scoutino. I posted on the next page because some were still insisting it was a .32-to-.380 swap.

    9. Walker, I just reviewed the AREX web-site, Directly from this web-site:
      REX zero 1 pistols are available in three sizes and all three variants are available in 9mm Luger, 9×21 mm, .40 S&W and 7.65 mm Browning (.32 Auto) calibers

  12. 9×19, 9×21, 40S&W and …..32ACP?!?!?!?!?!?! Since when have we seen a 32ACP that weighs over 20oz??? James Bond surely would sink like the proverbial rock! REALLY??? 32ACP???

    1. The Arex is not Slovak in origin-it’s Slovenian (part of the former Yugoslavia) as the author stated. Those two countries are separated by Austria or Hungary.
