Arex Introduces New Striker-Fired Polymer Pistol — Arex Delta First Look

Arex broke into the market in a big way with the introduction of the Rex zero 1S. The pistol was not revolutionary or chock full of new features. Instead, many labeled its reliability as the ultimate SHTF gun—an improvement on current popular models all combined into one gun. The zero 1 was followed by the Alpha, an out-of-the-box competition-ready pistol with an MSRP around $1,000. For 2019, Arex is set to release the Delta, a striker-fired polymer pistol, and The Shooter’s Log went to Slovenia to get a first look at the prototype.

Last year, I received an invite to Slovenia to get a firsthand look at Arex’s manufacturing facility. Slovenia is not normally the first that comes to mind when you think of precision manufacturing. However, I can assure you, many of the machines used by your favorite manufacturers were designed and built at the Arex factory.

Building on the success of Arex’s first offering, the Arex Rex zero 1S, the company quickly followed with compact and tactical models. During my visit last year, we were treated to the Arex Alpha. The Alpha is an out-of-the-box target-ready pistol with a street price of less than $1,000.

While we loved the ultra-tough, solid, well-built zero 1, the 800-pound gorilla in the room still remained: When would Arex come out with a polymer version? The design and marketing teams both smiled and advised, “Perhaps it is in the works.” Knowing that, it was not a big surprise when I returned to Slovenia a couple of weeks ago for Arex’s new introduction—the Delta.

We were invited to a sneak peek test of the prototypes of the Delta. Arex had already noted a change or two that would be incorporated into the final production version. The Delta is a polymer-frame, striker-fired handgun chambered in 9mm. By comparison, I would roughly equate the size to my Smith & Wesson Shield.

Arex offerings thus far did not seek to create new technologies. Instead, the company looked for the best features across the industry, combined them into a single pistol, and then looked for ways to make improvements. The result has been nothing short of stellar.

I do not want to get too far into the details because the units we tested were prototypes. That being said, the Delta is a shooter. You can imagine what happened when they let a handful of writers loose on the range with a new gun and free ammunition…. Prototype or not, we started hammering the steel targets and making a lot of brass. As quickly as one writer would set down a gun, someone else would grab it and repeat the abuse to the steel targets.

What We Do Know

The Delta will feature steel battle sights, so you can rack the slide one-handed using a tactical vest, belt, pocket, etc. The trigger pull may change, but the prototypes were at about 6 pounds and felt similar to a two-stage with some slack before the wall. They broke cleanly with a short reset, which will provide fast follow-up shots.

The Arex Rex Delta will ship with 15- and 17-round extended magazines. The grip is modular with changeable inserts. We had several sizes, but the choices will likely be narrowed to three or four by the time the final version is ready for market. The grip texture was aggressive enough to offer good hand purchase without feeling like 80-grit sandpaper.

During initial testing of the prototype models, the author noted that after thousands of rounds, the Delta never experience a failure to feed, fire or eject.

All controls are ambidextrous. The initial version will ship without a manual safety. However, understanding that market forces or individual department requirements may require a manual safety, Arex designed the Delta with the safety. That gives Arex the ability to either upgrade shipped models or ship Deltas with the safety in the future.

During the testing, a quick competition was held among the writers. The gun with the medium-grip module seemed to fit my hand the best and by chance had the thumb safety. Over the course of about 400 rounds or so plinking and shooting for speed in the competition, I never had a problem manipulating the safety. Neither did I engage it by accident.

When the smoke had cleared, the writers had fired several thousand rounds through the four or five prototypes, both under relaxed and stress (competition) conditions. There was never a failure to feed, fire, or eject from any of the prototypes. Given the history of Arex’s previous offering, this was not a surprise.

Estimates for the initial MSRP of the Delta are in the $450 range. That should leave it with a street price around $400. Would I trust my safety to the Delta? Given the results I have seen in the prototypes, I have already placed my order….

Arex is planning to finalize the design and hopes to have production models in the U.S. in December and on the street after the Shooting Hunting Outdoor Trade (SHOT) Show in January 2019. Check back in December for a full review.

  1. I own the Arex Rex O1s & the Arex Rex 01c,& I really like them. They came sighted dead on, & after 1,000 of rounds through both the s & c models are flawless. After 3,000 rds. & shooting real dirty ammo I had to clean the firing pin on the s model. I quit shooting cheap reloads & shoot only factory made bullets now. Both pistols are 100% sure fire & very accurate.

  2. I got a American Tactical omni hybrid its a polymer AR15 every time I shot it I smelled plastic burning that can’t be good. So i kept all the steel parts and ordered what I needed to make it all metal. I think the AREX will have the same problems

    1. Complainer! What? you also probably don’t like the smell of napalm on a beautiful bright sunny morning.
      Sheesh. Some people! :-p
