Why I Like The ‘Perfect Dot’ Sights from Night Fision: [VIDEO REVIEW]

These Perfect Dot night sights are awesome.

Do you need night sights on your everyday carry (EDC) gun? Well, you probably don't need anything besides food, water, and shelter to survive. And a new set of night sights isn't going to turn you into Jerry Miculek overnight. But these Perfect Dot sights from Night Fision are a great upgrade for your EDC. Whether it's an upgrade from the factory sights or another company's, these sights are legit.

There are two main types of night sights and one often mistaken for them:

  • Self-illuminating sights- These sights use a radioactive element called Tritium that glows on its own. Tritium has a half-life of 12 years, which means after 12 years, that same Tritium will be 50% as bright as it was originally. Don't worry, Tritium is used in a number of everyday products and only poses any health concern if it is ingested or absorbed into the body. So as tempting as it may be, don't eat your night sights and you will be just fine.
  • Photo-luminescent- These require a light source to ‘charge' them so they can glow. These glow brightly at first, then slowly lose their brightness and ultimately go dark after a few minutes.
  • Fiber-optic- I will mention these to dispel any confusion. They are not actually night sights as they don't actually provide any of their own light. The fiber rod simply refracts ambient light to appear brighter.

If there were no alternative, ‘charging' your night sights would be the only option. But because we have Tritium, I wonder why anyone would choose a set of photo-luminescent night sights.

If you want a bright sight, you need more Tritium. Night Fision claims to use 30% more Tritium in their sights than any other company. Are they brighter? Take a look at my XS Big dot, Sig X-Ray, and Night Fision sights side by side in complete darkness.

Comparing the brightness of these sights in complete darkness.

Night sights are not just for low-light use. In the daylight, a large, eye-catching front sight is ideal. This helps out eyes to quickly pick up the front sight, place it within the rear notch, and superimposed on our target. Night Fision has a patent-pending process design that they say makes the Perfect Dot sights brighter in day and night, and more durable. Here is how they describe it:

When it comes to Tritium gun sights, aluminum sleeves and painted-on white rings are the norm. Night Fision breaks the mold, literally. Our patent-pending injection molded sleeve design not only holds our Tritium vials securely in place, it creates a brighter and more durable ring, we call The Perfect Dot™, that provides maximum visibility both day and night.

Again take a look at the same sights side by side. This time in the daylight. They all are prominent and grab the eye's attention, but the added durability of the Perfect Dot sights make them even more appealing. One thing appealing about the XS Sights Big Dot is that the front sight is so big. At least for a lot of shooters.

While the Night Fision's dot is not as large, it is pretty darn close. Size is important, but the larger the front sight gets, the more difficult it becomes to be precise with your shots at a distance. So the size of this front sight dot may hit the sweet spot for users who want a big dot, but not very large.

A prominent front sight dot is ideal for defensive handgun sights.

Do you want a front sight color other than orange, green or white? Maybe you have some color blindness, compromised vision due to age or injury or some other reason why you prefer a specific contrasting color for your front sight. You can choose blue, red, orange, yellow, or white and all the colors are hi-visibility.

Outside of personal preference, color probably won't matter too much. However, take this bit of trivia into account. As it gets darker and darker, the colors that our eyes can pick up starts to diminish. Essentially moving from color vision to more of a black, white, and gray. The last color on the spectrum that disappears in low light is green. This is why many hi-visibility, safety products have transitioned from bright orange to bright yellow/green.

I chose this hi-visibility yellow color front sight for this reason. Will it help me shoot better? No only practice will do that. But, it is a color that I find is very easy to pick up across many different backdrops.

You can get a ‘perfect dot' in one of these colors, and choose what type of rear sight to pair it with.

Night Fison produces a traditional square notch rear sight, as well as a “U” notch rear sight. Like front sight color, the shape of the notch is a personal preference, rather than something that will revolutionize your shooting fundamentals. But it is nice that they are forward-thinking enough to produce rear sights in both variants.

Personally, I like the U shape rear notch. I find that the U shape gives you a bit more space in the rear notch to keep your front sight visible, without taking away what would be needed for combat precision.

I am glad to see that the face of the rear sight is flat. My opinion is that for any rear sight to qualify as a good self-defense sight, it should have this flat face. In other words, the front face must be a 90-degree angle to the top of the slide. This just makes one-handed manipulation easier than one with a sloped angle.

Will you ever have to rack your slide with one hand by catching the front sight on your belt, holster, or some other object? Hopefully not, but given the choice between a sloped rear sight, and a flat one, I know which one I would choose.

The 90-degree angle on the rear sight makes it easier for one-handed manipulation.

There are also varying opinions if the rear sight should have dots, or if it should be completely black. You can select a rear sight in a traditional 3-dot set up, where the two rear dots are Tritium filled and rather prominent. The other options are a rear sight with no dots at all, or a rear sight with two Tritium filled dots that are smaller and less prominent.

Once again, personal preference here, but I don't like my eye being drawn to flashy rear sights. So I prefer either the blacked out or diminished dot rear sights. The ones I ordered have diminished dots. I find this gives me the reference points when I need them in low light or bright lights, but they aren't distracting to my eyes.

The materials the sights are made from matters, especially if this is going on an EDC gun. These sights are made from 4140 steel. It may not seem like a big deal, but for an EDC gun that will be banged around and used in training, you want something that will last. If your sights get deformed simply dinging it on a barricade or from some hard training, get something else.

You want to train with your gear, not be so worried that your gun or sights will break that you never push your limits. I have seen far too many sights made from cheap metal that get marred during basic installation.

You can get these sights for Canik, Glock, Smith & Wesson, Sig, Springfield, and CZ. And don't worry if you have an optic on your gun, or are super cool and have a suppressor. You can get all these sights in suppressor-height. Tritium is a regulated commodity, and not just anyone can work with the stuff. Night Fision has been working with Tritium for 25 years as they produced the US Miltary's Tritium filled lensatic compass. So they know a thing or two on how to properly encapsulate Tritium so that it lasts.

Upgrading from stock sights is a worthwhile investment.

And finally, you're going to have to spend at least $100 on a good set of Tritium night sights, and some will set you back nearly $200 dollars. These Perfect Dot's are around $115 on the website, and given their durability and projected longevity, I would say that's a steal.

As usual, full disclosure, I reached out to Night Fision because of all the praise I have heard surrounding their sights. They sent me a set of sights to evaluate in exchange for an honest (I wouldn't provide anything less) review. Overall I really like these sights and if you are looking for a sight upgrade, I don't know how you could go wrong with a set of these.

    Hello Matthew
    Great review by the way. Was wondering if you could get a picture of the sights lined up and in focus together. I understand it can be difficult to do. I’m looking to buy a set of yellow/green and U notch rear night fision for Glock 19.

    Having a hard time finding a quality picture of the sight picture for these particular sights.

    Thank you for your service.

      Hey Thank you David! I tried to get some photos of them both in focus but I can’t do it with my camera. Perhaps someone with a better camera could do it. Sorry. Thank you as well for your military service!

    Hello, I am considering this sight system for my p320 compact. Which size did you choose for the front blade #6 or #8?

    • Matthew Maruster on January 10, 2020 at 7:40 am

      Hey Jay, the compact P320’s get the #6 and full size get the #8. Hope this helps 🙂 enjoy the sights!

    • Craig on March 2, 2020 at 3:51 pm

      Actually, i have the P320c and it is 8. You can look at your front sight on the left side it is marked 8. So, 8 front and 8 rear is what you want

    Hey Matthew, I was looking at XS sights till I read your review. Only because of who you are, will I seriously consider Night Fision sights for my PDP F-Series 3.5. God bless!
