Arex Delta Gen2: How Gun Designs Iterate and Improve

In firearms, as in really all technology, the market iterates and improves concepts over time. A novel new system – like the polymer-framed, striker-fired semiauto pistol – will never be perfect on its first introduction. Over time, as users and manufacturers gain more insight into the details of using and building the system, changes are made to improve it. At the same time, the cost of production comes down (especially after applicable patents have expired).

The Arex Delta Gen2 pistol is a really good example of this, I think. While offering no fundamental innovation, it is markedly better in all sorts of ways than similar pistols that preceded it. It has great handling, safe disassembly, near-universal optics compatibility, slim lines, light weight, and a good trigger. And it does this for a remarkably low price.

I am looking forward to really putting one through the wringer at Slovenian Brutality this June!

  1. The price of almost everything goes down at about 3% / year compound, due to all of those factors of improving skill, knowledge and manufacturing techniques

    Some things like plastic pistols, TVs, computers and phones go down even faster

    Trouble is, we were getting robbed by about 5% inflation of the money supply/ year, again – compound. Making it look like prices go up over time

    Keynsham economists tell us that very nasty things would happen if we weren’t being robbed by money printing.

    In the first 3 months of Lockdown in 2020, the central banks coordinated in increasing money supplies by over 40%, an they’ve kept going

    Robbery writ large

    Ps
    Ian getting into matching colours…

    Careful with that- you might get tranzd

  2. Polymer pistol frame production was a great improvement but the locked breech gun came with, was the real improvement which no appearent attempt over it seen up to that time…

    The patented trigger action of that gun comprising only four moving parts was the key of that success and striker firing was a part of this combination providing manufacturing cost save.

    The guns made after that gun with quasi appearance with similar trigger pull weight and pull distance were all produced with lesser safe and more cost which also lesser success… The striker firing of all them were only an item for resemblance support and most of them could be made with hammer firing with lesser cost.

    The real improvement… If to be made… should be a trigger system consisting only three moving parts…

    IMHO…

  3. Improvements… Even the greatest…
    M1911/M1911A1…M1903/M1903A1/M1903A3…M1921/M2HB…M1919/M1919A4…M1917/M1917A1

    • Less improvements than refinements.

      For instance, the changes from M1911 to M1911A1 were mainly to make the pistol more “user-friendly” for people with smaller hands, hence the relief cuts on each side of the frame just behind the trigger and the shorter trigger. The arched mainspring housing was to “push” the muzzle upward relative to the palm of the hand to counteract the pistol’s tendency to shoot low in instinctive shooting.

      The change from M1903 to M1903A1 was a genuine improvement, namely the improved M1906 cartridge.

      The major differences between M1921 and M2HB were going from water-cooling to air cooling to save weight, and the introduction of the hydraulic buffer (which is what “HB” actually stands for, not “Heavy Barrel” as usually stated) to reduce rate of fire to improve controllability on a tripod or flexible vehicle mount.

      As for the Browning .30 MGs, the changes were mostly to streamline production. They really had little or no effect on the way the guns were actually used, but then John Moses Browning got it right the first time, as he generally did.

  4. I own an Arex Rex Zero 1S, and I cannot speak highly enough of it; Excellent build quality, feels great in my hand and shoots very well. I hear good things about the Deltas, though I have not used one.

  5. Ah, let’s see, it is meant for 9 x 19, yes? And one might mention the optional (also ambidextrous) manual safety catch. And Arex is from, oh Slovenia (not Slovakia), time to learn flag recognition for all the former Yugoslav republics …Details, piddling details.

    • “(…)oh Slovenia (not Slovakia), time to learn flag recognition(…)”
      You are apparently not first to make such error, according to https://www.politico.eu/article/slovenia-and-slovakia-the-lands-of-confusion-2/
      Erwin Fouéré, the head of the European Commission’s delegation to Slovenia, recalls getting a memo recently intended for the Commission’s office in Slovakia.

      And a Slovene ambassador in one European capital says his staff meets someone from the local Slovak Embassy at least once a month, simply to exchange wrongly addressed mail.

      Slovenia’s soon-to-be commissioner Janez Potocnik says such incidents will surely pass with time: “Although we have also been mixed up with Slavonia.”
      (yes, to enhance confusion there is also Slavonia which was place inside Yugoslavia, but it did not yielded own country after break)

      • That both countries Slovakia and Slovenia also use the same colours in the white, blue and red in the same order does not really help to differentite them easily from each other, either. At least the Kingdom of Slavonia used to be distinct with blue-white-green.

  6. I have a friend who works in a shooting range, now I called him up, promised that if I approached, he would let me shoot with such a pistol, I’m looking forward to it.
