## Overview

The Viridian Reactor R5 Gen 2 is a cutting-edge green laser sighting system engineered exclusively for the Glock 43. Featuring a powerful 5mW Class 3R laser with ECR Instant-ON technology, it activates automatically upon drawing from its custom IWB holster—eliminating fumbling and delays. Its adjustable windage and elevation settings provide precise targeting, while the Radiance taclight technology offers twice the horizontal illumination for superior situational awareness. Crafted from high strength thermo molded polymer, this lightweight yet durable system is optimized for concealed carry, law enforcement, and tactical use, delivering up to 3 hours of continuous battery life and effective targeting up to 100 yards in daylight and 2 miles at night.

Review: Difficult to Change Batteries - Have used Crinsom Trace for years but thought I would try Viridian’s on my new M&P Shield based on price point and instant on feature. Not disappointed. Easy to install, bright, and probably won’t need much adjustment. Be careful not to strip screw heads when installing. Follow up. Am returning this laser. The batteries are difficult to change. The three small screws that must be removed are easily stripped if you are not VERY careful. The magnetic switch does not always switch off, or stay switched off when re-holstering, so the batteries don't last very long. Less than a day in one case. Sorry to return, but not practical for me.
Review: Not close to accurate, won't be able to keep at zero. - Near impossible to keep at zero because the laser is at the bottom of the sight so it is inches away from the barrel instead of at the top of the sight. So there is a massive change at any different distance which would be halved if the laser was next to the barrel instead of atvthe bottom. Then it moves around whenever you bump the sight, so apparently it isn't very secure either. On/off button is recessed so it is hard to turn on. Supposed to be auto-on but isn't. Not nearly worth the price but one of the only option not costing $300, just a really bad design. Very dissappointing. Then they contact me to offer a refund but it's really just their "permisdion" for a standard return but wonz't say that ubtil I get very specific. I don't need theur permission to return something and if they had lookec I hsve already returned one other product of theirs. Felt insulting and had my time wasted.
