XS Sights’ upgraded pre-drilled night sights for S&W and Ruger revolvers for self-defense make do-it-yourself installation quick and easy, without the assistance of a gunsmith. New, pre-drilled front sights, featuring a self-illuminating tritium Glow Dot, are now available for S&W K-Frame, L-Frame, J-Frame and Ruger SP101 revolvers. The dual-illuminated front sight has a self-luminous tritium vile surrounded by XS’ proprietary photoluminescent Glow dot that absorbs ambient light to glow in low light. The pairing ensures the front sight will glow brightly in low light and contrast well in bright light conditions. While the Standard dot sets come with a front sight only, the Minimalist sets come with a front sight and serrated, anti-glare, non-tritium rear sight. 

Retail: $64.99-$109.99.
