Bright 5mW Green Laser – Daylight-Visible Performance
Green lasers are easier for the human eye to pick up, especially in bright or mixed lighting. The LG-485G uses a 5mW green laser diode (approx. 515–532 nm wavelength) that stays visible in a wide range of real-world conditions. Range USA+2OpticsPlanet+2
Performance at a glance:
Output: 5mW Class 3R green laser for fast visual acquisition. OpticsPlanet+1
Wavelength: About 532 nm, tuned for high visibility. OpticsPlanet+1
Effective zero distance: Factory-sighted at 50 feet, ideal for typical defensive shooting ranges. OpticsPlanet+2OpticsPlanet+2
Dot size: Roughly 0.5" at 50 ft, giving you a crisp aiming point without covering the entire target. OpticsPlanet+1
From dim hallways to parking lots at dusk, that bright green dot makes it much easier to confirm where your muzzle is pointed—even when your iron sights are hard to see.
Instinctive Activation™ – Grip and the Laser Just Comes On
Crimson Trace’s signature Instinctive Activation™ system is the secret sauce that turns a laser into a true defensive asset. The LG-485G features a frontstrap/trigger guard pressure pad that activates the laser the moment you establish a normal shooting grip. Crimson Trace+2Shooting Surplus+2
Benefits of Instinctive Activation:
No tiny button to hunt for during a high-stress encounter.
As you draw and grip the pistol, the laser automatically illuminates.
A master on/off switch lets you disable the laser when you don’t want it, such as during dry-fire with irons only. Shooting Surplus+1
This “grab-and-go” activation method matches your natural defensive draw stroke, so the laser is there when you actually need it, not just when you remember to flip a switch.
Trigger Guard Mount – Slim, Snag-Free, and User-Installed
The LG-485G Green Laserguard uses a trigger guard mount with a clamshell design, so it requires no rail, no frame cuts, and no gunsmithing. Crimson Trace+2Impact Guns+2
Installation highlights:
Two halves of the housing bolt together around the trigger guard using included screws.
Installs in minutes with basic tools—user-installed and fully reversible. Shooting Surplus+2Impact Guns+2
Once tightened, the unit feels like part of the gun, with a low-profile shape that won’t snag on holsters or clothing. Firearms Pulse+2Global Ordnance+2
Because the Shield 45 is often carried concealed, that slim, snag-free design is a big deal.
User-Adjustable Windage & Elevation – Dial in Your Zero
Out of the box, the LG-485G comes factory sighted at 50 feet, but Crimson Trace includes windage and elevation adjustments so you can match the laser perfectly to your preferred point of aim. OpticsPlanet+2Shooting Surplus+2
Fine-tune the dot to coincide with your iron sights at 7, 10, 15 yards, or leave it at 50 ft—it’s your choice.
Simple adjustment screws make it easy to re-confirm zero after battery changes or a long period of carry. Shooting Surplus+1
This adjustability lets you tailor the laser to your ammunition, shooting style, and typical engagement distances.
Durable Polymer/Rubber Housing – Built for Everyday Carry
The LG-485G uses a tough polymer/rubber combination housing designed for real-world carry, not just range use. OpticsPlanet+2Adorama+2
Impact-resistant polymer body absorbs bumps, drops, and daily holster wear.
Rubberized activation area offers a positive tactile surface when you grip the gun. OpticsPlanet+1
Overall size of about 3" (L) x 1" (W) x 1" (H) and around 4 oz keeps the Shield 45 lightweight and balanced. OpticsPlanet+1
Water-resistant design means it will keep working through sweat, rain, and typical EDC conditions. OpticsPlanet+2Adorama+2
It’s built to live on a working defensive pistol—not just sit pretty in a safe.
Power & Runtime – 1/3N Lithium with “Free Batteries for Life”
The LG-485G runs on a single 1/3N 3V lithium battery (or two 357 silver oxide cells, depending on configuration), providing around 2 hours of continuous green laser runtime. OpticsPlanet+2Shooting Surplus+2
Power system benefits:
Crimson Trace backs the unit with a 3-year full/limited warranty (depending on program/region), giving you extra peace of mind. OpticsPlanet+2OpticsPlanet+2
Ideal for Concealed Carry, Home Defense, and Training
The LG-485G Green Laserguard is built for serious defensive use:
Concealed carry: Maintains the Shield 45’s thin profile while providing a bright, intuitive aiming point from awkward or compromised shooting positions. Crimson Trace+2Sportsman's Warehouse+2
Home defense: The green beam gives rapid confirmation of muzzle direction in dark or low-light rooms where iron sights are hard to see.
Training & dry fire: The laser dot exposes flinch, trigger jerk, and sight alignment errors, making your practice sessions more productive. Adorama+2Global Ordnance+2
