Arex Rex Delta Pistol, an All New Self Defense Handgun from FIME Group

World traveler, Mike Searson, gives us a first look at the Arex Rex Delta Pistol from FIME Group, ahead of its U.S release date.

USA – -(AmmoLand.com)- Earlier this year I wrote about the Rex Zero 1 Tactical. It left me very impressed with not only its reliability and accuracy but also its workmanship. So when the manufacturer Arex and the US importer and distributor, FIME Group invited me on an all-expense paid trip to Slovenia to see the factory and shoot the new pistols that will be rolled out at SHOT Show; I couldn't say no.

We can talk about the factory visit next time out. This time I want to tell you about their newest pistol: The Arex Rex Delta Pistol.

In all honesty, I expected to see another SIG clone. Maybe a SIG P220 or a SIG P210, but Arex continues to surprise, and in this instance, the Delta is a polymer-framed, striker-fired 9mm handgun.

You may be thinking, big deal. If you've seen one piece of fantastic plastic, you've seen them all. Not in this case.

Arex Rex Delta Pistol – The Good

The Arex Rex Delta Pistol is an entirely new design from the ground up. Similarities to the Glock 19 will be drawn, of course, but that is just a base form of reference. If you're reading this site, you should know what a Glock 19 is. If you don't, maybe you're reading the wrong stuff.

All in all the Arex Rex Delta Pistol is a very well-made piece and I look forward to future in-depth testing once they are available stateside.

One of the first things we noticed were the excellent front and rear cocking serrations, and the pistol is about 2 ounces lighter than the G19 mentioned above.

However, the highlight of the Delta is the way it breaks down. You slightly pull the slide to the rear, push down the two front tabs, push the slide forward, and in a most unusual move, you flip the slide off to either side. There is no pulling the trigger or pushing down on an internal lever as one would do with a Glock or Smith & Wesson M&P, respectively.

To reassemble you simply tilt the slide on from either side and pull it rearward.

It's that simple, and it eliminates the error we have made more than once of putting the slide on at a cant and having to resort to hitting it with a rubber mallet to get it off. That was not one of our more exceptional moments.

There is a provision to add a manual safety. However, the pistols will not ship with one. This option is in anticipation of police departments or folks who live in states where a manual safety is required on semiautomatic handguns.

Of course, the pistol is fitted with a Picatinny rail to add a weapon-mounted light or laser. Spare magazines will be available from FIME as the new design rolls out for about $20 a piece and they are quality mags manufactured by Mec Gar.

Factory sights are the same size as a certain pistol manufactured in neighboring Croatia and are currently available from a few manufacturers. An assortment of holsters are in the works, and more manufacturers should come on board in 2019.

The pistol will ship with four interchangeable backstraps in order to better fit an individual shooter's hands.

I witnessed a handful of the Arex Rex Delta Pistols being shot by media colleagues and Rex employees without a single malfunction.

Arex Rex Delta Pistol – The Bad

I found the factory trigger to be a bit too rough. Not just the pull, but the actual profile of the trigger was a bit abusive on the finger. FIME assured us that the final version would be much smoother and we encouraged them to get a sample gun to Randy Lee at Apex Tactical as soon as they can for something to blow the doors off this one.

The factory sights (black rear with white dot front) were a bit narrow and at times difficult to see. I did fire one model with three dot sights that were green and possibly Tru Glos, and that one served me well.

Truthfully, these are not bad things on an early version of the pistol and hopefully will be rectified by the time of the US release.

Arex Rex Delta Pistol – The Reality

The market may be flooded with plenty of striker fired 9mm polymer pistols, but the Arex Rex Delta is worth taking a look at with its innovations.

As you will see in our next article on this subject, the Arex factory is one of the most advanced firearms factories I have ever visited, and their QC is top notch.

If you heard Slovenia and envisioned a third-world type factory with workers turning out firearms on machinery made before the Second World War, you couldn’t be more wrong. These pistols are well made, reliable and have a massive potential in the CCW and law enforcement markets.

All in all the Arex Rex Delta Pistol is a very well-made piece and I look forward to future in-depth testing once they are available stateside.

    1. Sounds like a nice gun once they get the trigger squared away. I’ll look forward to checking it out in person. At that price it wouldn’t hurt. Of course that’s all dependent on the feel of it in my hand.

    2. My question is how did it feel in the hand? It looks like it might be uncomfortable with how it is shaped, did you find it to be? The fact it takes XD Sights, $20 mags, and all that – and comes in at $449, this looks like a real winner.

    3. What is the issue with having to pull the trigger on the Glock pistols? If you’re to stupid not to make sure you’re weapon is clear before you start to disassemble and clean it, you have no business touching any firearms. You can’t fix stupid. The idiots that fire a weapon unintentionally will find a way to do this with any weapon no matter how well engineered or built. I’m sure this is a good weapon and works as designed, but offers nothing different that isn’t available from a dozen+ designs already out there. BY AMERICAN….

      1. Never been a problem for me, but apparently it is an issue for police departments as that has been the key move for many of them toward the S&W M&P or the SIG 320 and away from the Glock.

      2. Some people simply are to stupid to own a firearm. My wife’s uncle says, “automatic pistols are too dangerous to own”, because he has a friend who accidentally almost shot his wife once. He sat down and started cleaning his gun and it discharged into the chair she was sitting in. He never checked the chamber immediately before he began to clean it, because he thought he had did that when he came in with it that day….this man was an armed security guard on a military base!!! I NEVER NEVER NEVER assume a weapon is empty. Even if I wanted to see you weapon and I watched you unload it, the very first thing I’m going to do when you hand it to me is cycle it a couple of times just to be sure it is empty….you can never be too careful, but you can definitely be too careless.

      1. Dimensionally the same or very similar to the G19…sorry I have no official spec sheet. Capacity is 17-rounds, 2 ounces less than a G19 and MSRP should be around $449…street price lower.
