Ruger Mark IV 22/45 – The Line Expansion Continues

Ruger 22-45

It seems that Ruger is “all in” on the new Mark IV line of .22 pistols. I’m not surprised, but I am a little awestruck at how quickly the company is swapping over its entire catalog from the older Mark III to the new Mark IV.

Take, for example, one of the latest guns to jump lines: the 22/45. The 22/45 in the Mark III line was very popular as it merged the ergonomics of the 1911 platform with the accuracy and reliability of the rimfire platform. As recently announced, Ruger is now making rhe 22/45 in the Mark IV line.

The new 22/45 uses the same one button take down that is one of the stand out features of the Mark IV guns. Likewise, the guns have an ambidextrous safety. However, instead of using the standard Ruger angle on the grip, the company uses a 1911 style grip angle.

Ruger 22-45

Adjustable sights are standard. The gun is drilled and tapped for the addition of an optic if desired.

Somewhat strangely, the Mark IV 22/45 introduction comes after the introductions of the Mark IV 22/45 Lite that was announced prior to the SHOT Show and the Mark IV 22/45 Tactical that rolled out in March.

These guns ship with a pair of 10-round magazines. Magazines drop free from the gun when ejected, and there is a magazine safety disconnect in the gun. This prevents the gun from firing when the magazine is out of the pistol.

Ruger lists the suggested retail price at $409. No, they are not approved for sale in California or Massachusetts.

    Doesn’t look like the old base model with fixed grips, but it appears to have an ambitious safety. Sounds like they are increasing the prices a little for the mark IV series compared to mark iii pricing, but that may just be to recoup R&D. Which would explain the order of releasing models.

    • iksnilol

      So the safety has plans for the future?

      • Jared Vynn

        Yes it hopes to be no longer be affiliated with politics and not be forced to be either “left” or “right”.

        Cursed autocorrect struck again.

  • codfilet

    Kinda want.

  • A Guest

    No threaded barrel? ok den

    • Treyh007

      They do have a threaded Mark IV but it’s the 22/45 Lite.

      • Shankbone

        There’s a Mark IV 22/45 Lite? Cool!

      • HSR47

        In theory anyway….

        They’re not exactly widely available yet.

        I really wish Ruger would stop introducing new models and focus on actually bringing currently announced products to market.

    • Gary Kirk

      There’s also the tactical..

  • allannon

    Does the barrel actually lack the obnoxious roll-mark from the mkIII?

    Regardless, I’m very tempted, even though I have a mkIII 22/45. Mostly by the Lite; I’ve been waffling on the mkIII lite since they came out.

    • PK

      The rollmark appears to be on the bottom of the barrel in the photos above.

      • allannon

        Oh, damnit Ruger.

        I guess that’s still better than plastered all over the side. A bit. :

  • Disarmed in CA

    Ugh, too rimfirey for CA
    I’d take another MK version, but every time I have $400 for a gun .22LR just doesn’t pop into my mind.

  • AndyHasky

    Ruger is going crazy expanding lines with new options and calibers, and they still haven’t released a frickin’ RAR in .17WSM! I thought when they discontinued the 77 they would be quick to chamber the american in all caliber’s they lost with the 77…

  • Slim934

    Thread dat barrel and then we’ll talk.

    • Jared Vynn

      That’ll be a different model, or the 22/45 lite they have out now.

      • Gary Kirk

        Or the tactical

  • marathag

    Why not make a metal lower,Ruger?

    Polymer, do not want.

    • Jared Vynn

      Why would you need metal? It’s a rimfire and the old mk III 22/45 had a polymer frame.

      • marathag

        Don’t need any of this stuff.
        It’s all about wants. regular Is and IIs were metal.

        Don’t like polymer on anything.
        For that kind of money, it better be metal

        • Jared Vynn

          The 22/45 has always been a polymer frame though. The target model mk IV is a steel frame if that’s what you want.

          • marathag

            But want the 22/45 shape in Metal.

          • DIR911911 .

            then buy a 3d printer and get to work

          • Jared Vynn

            Get the volquartsen target frame once they come out with a mk IV model.

          • LGonDISQUS

            You fed the troll. ?

  • John

    Shot the new Hunter model, looks both futuristic and retro, is very accurate and super reliable. The new take down method is so easy I see why they are switching to the Mark IV so quickly. If you get the Volquartsen trigger you can get a 2.5lb trigger pull with NO magazine disconnect!

    It does sell for around $650 but I don’t mind spending on high quality (and very cool looks). This is going to be my next.22!

    Loved my Ruger 22/45

  • LazyReader

    And doesn’t just look like something sean connery would use to kill a man

  • scaatylobo

    Ruger pisses me off.
    After SUFFERING for DECADES with their ” cannot be taken down without three hands ” models.
    NOW they don’t give us a break by passing out the kit we have to BUY to make the MILLIONS of older guns an easy take down = no,they tell us to buy another gun.
    FK THAT, might as well buy the S & W that came out with the takedown button FIRST.
    Ruger did not make any friends .

    • Jared Vynn

      Dude they couldn’t make it a kit, the differences in the frame/receiver are too great. Why complain about them making a new upgraded model just because you can’t retrofit the old ones? Sounds more like you just don’t like Ruger.

      • scaatylobo

        First because S&W came out with the very same idea FIRST.
        Then Ruger saw that tghere were kits that are for saleou need do to take down the Rugers [ of which I still own 3 ].
        Ruger could have done the retro fit as they did not fix the problem UNTIL it was done by another company first.
        AND the “fix” has been on the market for a decent time now.

        • Independent George

          1. The SW doesn’t have a takedown button; it needs to be unscrewed.
          2. Given how long it takes to develop a gun, let alone retool the production line, the Mark IV was certainly in development before the Victory was released.
          3. The fact that you still bought three Rugers despite the takedown issues indicates that you actually like the old guns in spite of the problem. So why are you complaining about something that you’ve gotten good use out of?
          4. If a retrofit kit is possible, then I’m sure that a company like Kidd, Volquartsen, or Apex will have one on the market soon enough.

    Magazine safety disconnect = not helpful for shooting those Super Colibris one at a time.
