We realize that sight selection can be a very personal choice, but with so many brands out there (and potential fit/point of impact variations) we decided it was time to offer sights a stand alone product. We call these "fighting sights" because they are optimized for that purpose on OUR pistols and slides. We have given a lot of thought to our sighting systems having tested and selected carefully a set up that will give you the best possible performance and value. Package includes rear sight and front sight. Select your front sight options below. Fit and Point of Impact: Perfect fit and point of impact on Shadow Systems slides Universality: Because our RMRs are so low, these sights give a tight lower 1/3 co-witness while still being a "normal" height. We ship these on both RMR and iron sighted pistols. Emergency Manipulation: The rear sight is dead flat on the front and hooks and racks easily against pockets, belts, pieces of furniture and human teeth (we would assume, not recommended). Multiple Front Sight Options: We offer a black serrated rear, a red fiber optic, and two tritium options. On a dedicated RMR gun, we normally recommend the black front as there is no reason to force your eye to track multiple "dots" under stress. Stick to the RMR--they rarely fail, and treat the irons as true back ups. The fiber optic gives the brightest front sight option under stress and can help older eyes track the sight. In general, they are great for speed and more economical than tritium, but somewhat limited at night. The green or orange outline tritium options are sort of the best of both worlds. The colored outline is a bit like the fiber optic by day and really draws in your eye. The tritium helps at night and these sights glow BRIGHT. Blacked Out Rear Sight: Yes, we believe strongly in a blacked out rear sight, even for nighttime use. Search around and you will see many experts agree. The reasoning: the addition of dots, bars, or boxes to the rear sight hurts front sight focus and tracking under stress by adding visual chaos to what you are seeing. This makes you slower and draws your attention away from what really matters: the front sight. "But wait, I need tritium dots on my rear sight to be effective at night!" We're not sure it is realistic to expect you'll carefully line up glowing shapes under the stress of a gunfight at night. If you press that big bright front sight toward the target under stress, you'll get the hit. The Right Light: There is definitely a "sweet spot" for the amount of light on either side of the front sight. Less light tends to increase precision, but the sight picture is blocky and obscures a lot of the target. Too much light and the front sight appears too thin and you loose some precision (harder to consistently center the front). We've thought about that too and carefully designed a combo that will allow you to center punch the paper or make a head shot but not feel like a blocky target sight.
