NEW PISTOL: Ruger Mark IV 22/45 Lite

Continuing with our march towards the 2017 SHOT Show in mid January, Ruger has just announced the 22/45 Lite version of their new Mark IV rimfire pistols. As with the previous MKIV announcement, the headline feature of the new Lite model is the easy push button takedown that separates it from previous generations of the iconic pistol.

Obviously, I’m delighted to see the the continuation of the threaded barrels, not a surprise after Ruger’s recent venture into the world of manufacturing affordable rimfire suppressors.

There’s no doubt that these pistols will sell like hot cakes.

    Very nice- I even like the copper color. I can’t wait to add this to my all steel Mk II.

  • Gary Kirk

    Damnit mdanit daminittt

    I really need to see my 22/45 Lite now!

    • thedonn007

      See or sell? I think I am going to stick with my mark III 22/45 lite. I got it for $350 used.

      • JumpIf NotZero

        Sell, this is not the golden age of autocorrect.

        • iksnilol

          Heh, autorrect. You still cling to your archaic gods, such as the pathetic autocorrect, do you not!?

          I pity thee, unleash yourself from the fetters and be a free man! AND I PROMISE YOU, YOU SHALL HAVE SATISFACTION!

  • Dude

    Shut up and take my money!

  • John

    Been holding off on a Mark IV for the 22/45 LITE…. but I’m hating that color choice. 🙁

    • JustAHologram

      I doubt this will be the only color

  • Mattie Dimes

    So how long do I have to wait for a TacSol barrel and matching can?

  • Marc

    I’ll stick with my Mark III. This new one is pretty fugly.

    I have always loved Ruger MK series .22 pistols. I currently own a MKII Government Target and a MKIII 22/45 Target model which I removed the horrid mag disconnect and LCI from. I will eventually own a MK !V hopefully when the excitement and prices come down. For the kind of money they want for these they really should offer models without the mag disconnect and fix the walking hinge pin on the rear sights. I get why Ruger uses the mag disconnect but instead of subjecting the whole country to a few of non free states rules they should offer certain state compliant pistols if they want to sell them in non free states. I never found the take down to be all that difficult on the earlier models, the instructions are in the owners manual, read and follow.

    I’d be all over this if I had not just bought a Victory. May still get one in the future.

  • Wayne Keller

    Does anyone know the MSRP for this pistol?
