Mansfield Two Dot Pistol Iron Sights

Lee Williams of The Gun Writer got the exclusive on Michael Mansfield’s recently patented revolutionary pistol sight.

Mansfield designed a new style of iron sights for handguns. It is still a traditional notch and post but it uses four half circles. Two on the front and two on the rear sight. When lined up, the half circles make a complete circle.

Lee tried out a prototype that was made out of plastic and handpainted with fingernail polish.

Lee saw immediate results when compared to a bone stock pistol.

Mansfield said his sight system is based on the Vernier Principle.

Mansfield called it the “Vernier Principle,” an idea he arrived upon after talking with his ophthalmologist.

Sorry to get all sciencey, but the Vernier Principal uses “alignment of line segments displaced by a small amount to make fine measurements. Human eye can easily detect this alignment of lines which is the main fact that drives a vernier.

Mansfield sights are still in the prototype stages. He is looking for a fabricator to machine them out of steel. His prototypes were for a Sig P226 and H&K VP9. However his first production sights will be made for Glock handguns.

    Pretty neat concept

    There’s an easier way to do this which they have used for many years in applications like airplanes where you need to align your sight. You have two balls that are of the same size aligned on the viewing axis. The far ball is red the near ball is white. When the white ball covers up the red, you are aligned.

    The key here is that any red visible means you’re not aligned, and it gives a concrete direction you need to move by showing a single red sliver. The major advantage is that it only requires you to focus on one sight plane, versus the two planes in this design.

  • It might work for precision applications, but those would be very slow.

    Its a neat concept, but I think the triangle/trapezoid sights on my Steyr will work faster.

    • KestrelBike

      I just feel like the above system would be slow for me to use.

    • BrandonAKsALot

      I love the sights on my Steyr. They are a good medium of speed and precision.

  • Martin Grønsdal

    by far not tactical enough for me.

  • valorius

    Someone has way too much time on their hands.

    • Badwolf

      And that’s good right?

    • FearlessFarris

      I know, right? Could have been playing Candy Crush.

    Vernier is a “fine” aiming method. This would be ideal for target shooting.
    But we still need “course” aiming methods. The usual notches work fine for this, then your can go into “fine” tune with more time and control afterwards.

      • Sand

        of course.

  • USMC03Vet

    Too much going on. No thanks.

    • Goody

      But that’s 33% less dot than a 3 dot sight!

  • Giolli Joker

    I wonder if this would require to be specifically tailored to the distance between the sights of the pistol.
    It may make no difference on any full size handgun, but a snub nose revolver would probably require slightly different size of the front circles compared to a 6″ barrel.

  • Dracon1201

    So no air whatsoever to see my target? These might be okay for competition where you can afford to obscure your target with a big rectangular box.

    • Blake

      That’s all this sight would be good for. It’s a “take your sweet time and try to hit that target that’s super far away” sight, not a “oh shit, take a quick shot to save your life” sight design.

  • SteveR

    I would like to try it. I think it would be faster than most of the commenters think and would certainly be more accurate. Just being fast to get shots off doesn’t help any it you are not hitting what you are shooting at. As with most shooting, it would probably take a little time to become proficient with them.
