Viridian RFX42 Micro Green Dot Sight – Shield Footprint

The Viridian RFX42 is a compact micro reflex sight with a green dot reticle, designed for concealed carry pistols and defensive handguns using the Shield RMSc footprint. The green dot offers improved visibility in bright outdoor conditions compared to red, making target acquisition faster in varied lighting. Built for reliable performance on carry pistols, the RFX42 provides a low-profile optic solution without requiring slide milling on compatible models.

The sight housing is machined from aircraft-grade aluminum with a matte black finish and sealed against water and dust ingress. Brightness settings adjust to ambient light conditions, and the unit is powered by a top-loading battery for easy replacement without removing the optic. The Shield footprint ensures compatibility with popular micro-compact pistols and aftermarket slides designed for this mounting pattern. Glass is multi-coated for clarity and light transmission.
