AREX Rex Zero 1 Handgun -Passes Yet Another Gauntlet – 1,000 Rounds Back-To-Back

Assuming Military Arms Channel’s AREX REX Zero 1 is representative of the batch of handguns, it would seem there is a real Sig “Killer” loose on the market (that bears a striking resemblance to it no less). So far, the AREX REX Zero 1 is the only only handgun to survive full “torture test” and “The Gauntlet” without a single malfunction.

Using 22 magazines, a few friends, and some sponsored ammunition, Tim fired 1,000 rounds through the handgun straight. Most firearms can be expected to last many times that number, firing 1,000 rounds straight is a rough duty cycle. Outside of repeated stress on the components, the heat from 1,000 rounds is prodigous, which causes various metal parts to react in different ways. At extreme temperatures, poorly manufactured steel can start to anneal or springs are liable to malfunction.

While the Sig performed well compared the the REX Zero 1 in the same torture test, its impressive for the handgun to go 1,000 rounds without a malfunction under the duty cycle. Frankly put, outside machine guns, weapons are not designed to handle that heat.

For those interested in the Slovenian handgun, the full-size model is currently imported into the US. The compact and “combat” models are being manufactured, but have not yet made it to our shores.

    Any new modern handgun should have absolutely no problem shooting 1,000 rounds in a row. I really don’t think this is impressive at all.

    • Lma

      Agree. Just be sure to replace the plastic guide rod in the Glock first.

      • hking

        The Glock 17 in the IV8888 meltdown did over twenty 33rd mags on full auto before the plastic guide rod gave up the ghost, I bet semi auto wouldn’t be as hard or hot on it, would likely make a full 1,000 rounds.

        • Twilight sparkle

          I’ve actually heard of more issues from steel guid rods than I have plastic

      • 40mmCattleDog

        A stock glock will go 1000 rounds easily, and yes on that plastic guide rod too.

    • the other cliff

      Any HK? If you try that with any of the P7 variants, be sure to film your hand spontaniously combusting as a lesson to the rest of us.

      • Rob

        I was going to bring this gun up. It would struggle with this test. Even if the pistol would be able too you couldn’t hold is past a few dozen. Incidentally I still consider it one of the finest defensive pistols ever made.

        • the other cliff

          Agree on all counts. With your average shootout running into the mid single digits of rounds fired and an extreme shootout resulting in a few reloads, how relevant to the real world is a 1,000 round, non-stop, torture test? I get the need to go 1,000 rounds between cleanings. I get that it is good to go 1,000 rounds without a stopage. Neither requires non-stop testing. That is just showing off.

          • Ron

            Or for that matter how many people can accurately fire from a handgun more than several hundred rounds in a setting.
            In a few shooting schools I have been through even while using a 9mm I start to have problems after as little as 400 rounds in a day.

          • Nimrod

            Don’t forget zombies dude, ZOMBIES! They eat brains and you need thousands of bullets to stop them.

      • hking

        I wouldn’t really consider a P7 to be a “new modern handgun” seeing as how they haven’t been in regular production since 2004 and only made in small 500 gun special batches up until 2008. Aside from that no, I dont think anyone would expect a P7 to run a 1,000 round shooting schedule flawlessly, and perhaps that is why its no longer in production (aside from being overly complex and expensive to manufacture)

  • John L.

    If they would release a .45ACP version, I’d likely go for one. However, I’m not holding my breath.

    And, to try to head off the caliber wars, .45 because that’s what my family has standardized on. (My wife likes shooting .45 much more than 9mm, even from the same weight of handgun, and if it makes her happy and wanting to join me more often on the range…)

    • Reef Blastbody

      I’d be all over a Rex Zero 1 in 10MM like white on rice. Just sayin…. 😀

  • I miss Frank James’s meltdown tests from the 1990s. The big one was 10,000 rounds of Winchester Silvertip through a S&W Model 1006 in roughly 6.5 hours. Component measurements, accuracy testing, and temperature readings were made before, during, and after.

  • Bullphrog855

    IIRC the average round count for a self defense shooting is upwards of 1000 rounds according to the FBI.

  • CS

    I’d like to see him repeat these tests, redo the 1000 round gauntlet with a dirty gun fresh from the envromental torture testing.

    • TW

      I don’t think any gun would pass that test with flying colars. Even a glock.

    • Send him 1,100 rounds of ammo and I’m sure he’d do it. And just to make it known, as I type this, the video has 81k views on YouTube, that equals around $175 in as share revenue .

  • Billy Jack

    Call it a Slig.

  • Reef Blastbody

    Actually, Nathan, the P226 Legion that was tested side by side with the Rex Zero 1 to inaugurate MACs new torture test regime didn’t fare too well at all. True, it’s a sample size of 1 example each, but the P226 Legion didn’t cover itself in glory. The P320 they tested later on fared somewhat better, but the Rex is still king of that particular mountain.

    • Holdfast_II

      What mags does the Rex Zero take? p226 or something else?

      • Gary Kirk

        Proprietary.. But I believe they list at $25 a piece

        • Reef Blastbody

          Gary, yes, they appear to also be Mec Gar pieces, but K-VAR/FIME sells them for ~$25 apiece. Not too terrible, all things considered.

          • Gary Kirk

            No real surprise there, Mec-Gar supplies magazines to many manufacturers.. Doesn’t mean they’ll be providing them on their own, at least for a bit.. But still at only $25 a piece, much better than buying a factory Sig mag to make sure you’re “factory compliant” for warranty..

          • Reef Blastbody

            Yep. I’ll be *real* happy when their non-compete agreement with CZ lapses for the P-07 and P-09 series. Nice guns, but CZ marks the magazines up ridiculously.

          • Holdfast_II

            Well, I’ve been using Mec-Gar generics in the Sig 226 and 229 with no problems. Being in a lame state I have to buy 10 round mags, and frankly I’ve been accumulating too darned many different ones, and so I’ve been trying to only acquire guns which can use existing mags.

  • TheBeavs

    I wish people didn’t get so but hurt about a lesser know gun doing well in a challenge or a torture test. I know very well that you guys would give praise if a Sig, HK, or whatever big named brand did well in the same test. Stop being a snowflake because you spent money on a gun and not all the gun reviews out there giving amazing praise.

    • Grindstone50k

      I’ll bite: My reason for not being impressed isn’t because it stacks up to big names, but because lesser brands can do the same. 1k is nothing.

  • A Fascist Corgi

    Not only is this gun more reliable than the SIG P226, but it’s also half the price. I feel especially bad for all of the people looking at their SIG P226 Legion with buyer’s remorse.

  • Hoover

    These torture tests, gauntlets, trials (whatever you want to call them) are largely worthless, other than the revenue they generate for the YT channel owners. They represent how a “single” example of a “single” model of gun will perform during that “single” test on that “single” day. A sample size of “one” is not a reliable indicator of how a model of gun performs. And, the test between guns shouldn’t even be considered, since the tests are performed on different days with different conditions; humidity, temp, air pressure, different lots of ammo, different consistency of test media, how many rounds the gun has fired prior to the test, etc. Lastly, these tests are so extreme that they represent a very low probability of the type of conditions one might encounter on a daily basis.

  • Spencerhut

    CZ mags are not compatible between the poly and classic guns. I’m okay with that since the P-07/09 mags are better than the 75 series mags. I own a butt-tonne of each and shoot them a bit. The P-07/09 have won me over. Also just got a P-07 Urban Grey to replace my older P-07 “Duty”. Great little guns with fantastic triggers out of the box.

  • Grindstone50k

    1k rounds! Wow! So amazing! Good thing it’s as reliable as sub $400 guns that have already been on the market for years!

  • Doug Larsen

    I seem to have good luck with “obscure and relatively inexpensive” handguns. First it was an Arcus 98DAC, which is ugly but runs like a top. Then a Canik Stingray, which is heavy but stone-cold reliable. Then I bought a Grand Power P1; an utterly reliable handgun that is much better than it has any right to be. And now I’ll add an Arex Zero to my collection of “What in the heck did you say that was?!?” handguns. And I suspect it won’t disappoint, either. Loves me some Glocks, FN’s and CZ’s too, but some of these lesser known handguns really hit it out of the park when it comes to overall “value”.

  • SpartacusKhan

    yeah, but I have a magwell, so I need the 18 round factory ($46.95 even there), and then extended baseplates. I got one of those 19rnd mecgars (really 17 w/+2 baseplate) and a flushfit base for carry to replace the +2 base, and it was quite a bit of work to shape the well and baseplate to get it to sink in all the way. I only wanted the one flushfit, so any new ones have to be the 18rnd factory, can’t find them anywhere else for less. Thanks for the heads up, tho.

  • Secundius

    Is there a particular reason why Gun Manufacturers put a “Disclaimer” to Actual Rounds Fired? One Thousand Rounds, But NO “Actually” ONLY 986-rounds Fired…
