The Viridian RFX Custom red dot sight for Walther PDP and WMP is a purpose-built reflex optic engineered for modern concealed-carry pistols with optics cuts. This Shield RMSc-footprint sight pairs a crisp 3 MOA green dot with Viridian's proven instant-on ambient light sensor, delivering reliable target acquisition in variable light without the bulk of full-size competition optics. At just 12.47 grams, it's one of the lightest reflex sights you can mount, keeping your carry gun balanced and ready.
Built for serious everyday use, the RFX Custom runs on a single CR2032 battery with an impressive 30,000 hours of runtime on the middle brightness setting. The automatic brightness control adapts the dot to your surroundings—bright and crisp in sunlight, dialed back indoors—while the instant-on function means it's live the moment you need it. The compact 16mm × 22mm lens and unlimited eye relief let you acquire your target fast from any shooting position, whether you're drawing from concealment or working from the bench. Housing is high-strength thermomolded polymer with IPX4 weather resistance, rated to function from -4°F to 130°F.
If you're running a modern Walther PDP or WMP with an optics cut, or building a pistol around that platform, the RFX Custom fits like it was designed for it—because it was. The sight sits low in the cut for a clean profile and co-witnesses naturally with iron sights if your gun carries them. At this weight and size, you won't feel it changing the gun's balance or handling; it's just there, doing its job.

The sight carries an IPX4 weather resistance rating, meaning it can handle rain, splash, and moisture in typical carry and shooting conditions. It's rated to operate from -4°F to 130°F, covering most real-world environments.
