Viridian Reactor G2 Red Shield 45

The Viridian Reactor G2 Red Shield 45 is a compact red laser sight engineered specifically for the S&W M&P Shield .45 ACP platform. This integrated laser system combines rapid target acquisition with the precision needed for defensive and training applications, delivering a visible red beam that enhances point-of-aim accuracy at defensive distances without adding significant weight or profile to the compact carry pistol.

The second-generation design optimizes performance across tactical duty cycles and training scenarios. Weighing only 0.38 lbs, the Reactor G2 maintains the M&P Shield's concealability while the red laser wavelength provides superior visibility in low-light environments and indoor ranges compared to infrared alternatives. The system is purpose-built for the Shield platform, ensuring zero compatibility issues and reliable holster integration. The included ECR Ambidextrous IWB (In-Waistband) holster accommodates both right- and left-hand carry, making this package versatile for different user preferences and operational contexts.

This configuration serves law enforcement officers, armed civilians pursuing concealed carry, and shooters who value supplemental aiming systems for low-light engagement. The .45 ACP platform appeals to those prioritizing terminal performance in a compact form factor. The inclusion of the ambidextrous holster eliminates separate accessory purchases, reducing decision fatigue and ensuring compatibility out of the box. Operators and instructors frequently specify lasers on Shield-platform pistols for transition drills, barricade work, and training scenarios where quick target reacquisition matters.
