Enter XS Sights' Big Dot and Standard Dot Night Sights—engineered to enhance your defensive firearm with unmatched clarity in any lighting condition. These night sights are a testament to modern ingenuity, utilizing a proprietary photoluminescent Glow Dot that absorbs ambient light and shines brilliantly in low-light situations.

Designed with practicality in mind, these sights cater specifically to those grappling with aging eyes or deteriorating vision. Their large size makes them highly visible, reducing the time it takes to acquire your target—a crucial factor in high-stress scenarios.
