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.

You can’t use these sights at all with a rmr. You try and use them the sights get covered by the rmr body.

Thanks for your comment. These sights are desiged to provide an extremely low co-witness. They may not make it over the battery housing of an optic that is mounted higher on slide than a direct milling. Please be sure to measure the height over topstrap to confirm the blade height will sit proud of the battery housing.

These sights are excellent. I have them installed on my G45. This is my primary duty firearm. In particular, the front and rear tritium design is simple yet intuitive for night fire. I only wish they were available for other makes and models.

These sights are spectacular. I love their function and brightness (of course, Night Fision is amazing). Would love to see Suppressor Height version and G43 versions in the future. Another great product. Keep up the innovation and I’ll keep buying.
