G10 Black/Gray Panels – Rugged, Aggressive, and Attractive
The LG-904G uses G10 composite side panels—an incredibly tough, layered fiberglass laminate favored in premium knife handles and duty gear.
Benefits of G10 construction:
High strength and impact resistance for duty and defensive use
Textured surface that offers a secure, non-slip grip, even with wet or gloved hands
Black/gray layered pattern that gives your 1911 a modern, custom look without being flashy blackwidowfirearms.com+2hookandtackleshop.com+2
A rubber overmolded activation button runs down the front strap area, providing both comfort and a natural activation surface for the laser. Abide Armory+4crimsontrace.com+4Palmetto State Armory+4
Instinctive Activation™ – Just Grip and the Laser Comes On
Crimson Trace’s signature Instinctive Activation™ means the laser turns on automatically when you obtain a normal firing grip—no extra switches or awkward movements needed. Classic Firearms+4crimsontrace.com+4Palmetto State Armory+4
Why that matters in the real world:
Faster target acquisition in defensive situations
No need to break your grip to hunt for a button
Works naturally with your existing training and muscle memory
You can still disable the system at any time using the master on/off switch, but in a crisis, simply gripping the gun brings the green dot to life.
Bright Green Laser – Daylight-Capable Aiming Point
The LG-904G’s green laser is designed to be highly visible to the human eye, especially in low light, dusk/dawn, or indoor environments. Impact Guns+2AmmoJoy+2
