NIGHT FISION TRITIUM NIGHT SIGHTS

When it comes to tritium gun sights, aluminum sleeves and painted-on white rings are the norm. Our patented, injection molded sleeve design not only holds our tritium vials securely in place, it creates a brighter and more durable ring.

STANDARD HEIGHT SIGHT INSTALLATION

When it comes to tritium gun sights, aluminum sleeves and painted-on white rings are the norm. Our patented, injection molded sleeve design not only holds our tritium vials securely in place, it creates a brighter and more durable ring.

The Costa Ludus sights were designed with direction from Chris Costa, based on his extensive background with the United States Coast Guard and as a firearms instructor. These sights have several unique features that set them apart from other Night Fision sights. Most notably, there are serrations on the front and rear sights to reduce glare. There are also serrations on the front edge of the rear sight to maximize one-handed manipulation. Costa Ludus sights include a proprietary Night Fision Perfect Dot® in the front sight and a horizontal tritium bar in the rear sight. The tritium bar gives the shooter a clear distinction between the front and rear sights in low light conditions. The rear sight is also cut to maximize the target picture for fast acquisition.

These offer an extreme low profile co-witness. They are recommended for use with a Holosun c-series or Trijicon RMR Type 2 mini-red dot optic. It is highly recommended you compare the blade height with your optic housing height to ensure where they fall in your window.

Rear tritium bar does not have the same volume of tritium as our 3-dot sighting system.

Costa Ludus night sights Glock gen 5 mos

Love the new sights on my Glock. I was looking into many different options and glad I went with these! Price was great and instillation was pretty easy. Thank you. Sights are brighter than all the rest I have looked at.

Missed the mark

These are a well built sight except for the rear tritium is so dim I can't see them at all at night. The front sight is excellent but the small line in the rear isn't. I am very disappointed as I assumed a product with Chris's name on it would be perfect. I hate to admit it but the marketing got me on this one folks.

An awesome product

The Costa Ludus night sight for my g43x are very well made. They sit just where I wanted them to, a 1/5 cowitness with my Holosun 507k X2. They durable, good looking, easy to install (without a “sight pusher”) and stand out at night. I took a pistol class recently that had a low-light no-light section late in the evening, after a full day of class, and I switched from the optic to the sights to get some reps in and these sights were flawless and so easy to use. I can’t recommend them enough.

Costa Ludus Review

The sights are built very well and the sight picture is exactly as shown. I installed them myself and it wasn’t very hard. I would definitely buy night fision sights again.

Great sights

Have used these for about a month now and they're great! Had another set of i-dot type sights on my gun prior which were also good but had sharp edges on the back which dug into my stomach throughout the day. These are machines perfectly with beveled edges which resolves that problem totally. They look good too.
