R3D 2.0 Night Sights Introduction


Purpose Driven Sights!

R3D 2.0 rear is serrated to reduce glare and features tritium lamps to aid in sight alignment in any lighting condition.  The 0.170” wide notch rear sight allows for more visibility on either side of the front sight post for faster sight alignment, especially in poor lighting conditions.  Like the original R3D sights, the 2.0 family is designed with a ledge to aid in one-handed manipulations.  The R3D 2.0 sights use brighter tritium lamps in the rear sight as compared to our original version to ensure that you can see the sights in poor lighting conditions.  The black PVC ring surrounding the rear sight lamps help create a more defined edge on the rear sight lamps to improve the sight picture and differentiate the front lamp from the rear sight lamps.


The 0.145” wide front sight is wider than many other options on the market and features a green Ember Glow Dot surrounding the tritium lamp. The photo-luminescent Glow Dot will absorb ambient light and glow in low light while the tritium lamp is self-luminous and will glow in low light/no light situations for 12 years.


Upgrade Your Sights!

Looking to customize your Kimber 1911? Sights are the perfect upgrade. Factory sights on Kimber handguns have a few issues, and XS Sights has you covered! A major issue with factory sights is the sight picture itself being difficult to see in different scenarios. XS Sights addresses this by increasing the size of the front sight, allowing for your eyes to easily pick it up in high-stress scenarios, and by adding tritium and photoluminescent materials for a dual illuminated front sight that is hard to miss. The tritium and glow dot emits a gentle glow that guides your eye to acquire the small light source making it easily visible in low-light scenarios. This is just one of the many reasons to make your first Kimber upgrade, an upgrade to XS sights!
