Note: Will not fit the S&W 686+ and is designed for round butt frames only. Always verify your exact revolver model and frame type before ordering. Hinterland Outfitters+2TJ Target - Quality Paper Targets+2
If you own a compatible K or L-frame round butt revolver, the LG-308 offers a direct replacement grip that adds a full-featured red laser without needing gunsmithing or permanent modifications when properly installed according to the manufacturer’s instructions.
Comfortable Rubber Overmold Grip for Large-Caliber Control
Crimson Trace built the LG-308 with a rubber overmold grip that wraps around the frame to improve purchase and tame recoil on robust .357 Magnum and .44 Special–class revolvers (depending on your specific model). Product descriptions emphasize: Glen's Army Navy Store, Inc+4Crimson Trace+4Hinterland Outfitters+4
A comfortable, secure grip that helps your hand lock in, even with sweaty palms or during long range sessions
A shape that supports natural pointability, matching the feel of traditional S&W service stocks while adding modern enhancements
Added control on large-caliber revolvers, an especially important factor for Hog Hunter–style and defensive wheelguns
Because the laser is integrated into the grip panels rather than mounted externally, your revolver retains a clean profile that works well with most open-bottom holsters designed for K/L-frame round butt guns (always test fit before carry).
Instinctive Activation – Laser Comes On When You Grip the Gun
One of Crimson Trace’s signature features is Instinctive Activation™. On the LG-308, the pressure pad is located on the front of the grip, directly under your middle finger. When you take a normal firing grip on your S&W K or L frame round butt revolver, the laser automatically activates. BOSQUE Outdoors+4Crimson Trace+4Shop | Shooters Jax+4
This design delivers several benefits:
No extra buttons to hunt for during low-light events or stressful situations
Allows you to focus on sights and target while the laser simply “appears” on the point of impact
Easily deactivated with the master on/off switch when you don’t want the laser illuminated (for dry fire, practice, or storage) Shop | Shooters Jax+2Night Vision Guys+2
Whether you’re dry-firing at home, training on the range, or setting up a lawfully configured home-defense revolver, this instinctive activation can help you get the dot on target quickly and consistently.
Precision Red Laser – 633 nm, 5mW, 0.5" Dot at 50 Feet
The LG-308 uses a class IIIa red laser module tuned to approximately 633 nm with 5mW peak power, which is the maximum legal output for consumer-visible lasers in the U.S. MyFFL Demo+2GearZone Tactical+2
Key performance specs: MyFFL Demo+2Impact Guns+2
Wavelength: 633 nm (bright red)
Output: 5mW peak, class IIIa
Dot size: ~0.5" at 50 ft
Effective range: Approximately 50 ft in bright conditions; farther in dimmer light
This fine dot size at typical indoor distances makes it easier to hold a precise aiming point on smaller targets while still remaining bright and visible in low-light scenarios.
User-Adjustable Windage & Elevation
The LG-308 ships factory sighted for typical defensive ranges, but Crimson Trace includes user-adjustable windage and elevation screws so you can fine tune point of aim to match your chosen load and preferred zero distance. BOSQUE Outdoors+3Shop | Shooters Jax+3Classic Firearms+3
This adjustability allows you to:
Match your laser dot to your revolver’s fixed sights at a chosen distance
Offset the dot slightly (e.g., a 10–15 yard zero) depending on how you train
Re-zero if you change ammunition, grips, or alter the revolver configuration
Always perform adjustments from a solid benchrest and verify zero with multiple shot groups for best accuracy.
Lightweight, Long-Lasting Power System
Despite its full-featured design, the LG-308 adds less than 1 oz of weight compared to standard grips, so it won’t meaningfully affect balance or carry comfort. The laser is powered by two CR2032 lithium coin cells, a common and widely available battery type. Chadwick Armory+3MyFFL Demo+3Impact Guns+3
Highlights of the power system:
CR2032 x 2 – easy to source and replace
Designed for solid runtime in typical defensive and training use (exact life depends on duty cycle and conditions)
Engineered with Crimson Trace’s focus on efficient battery management and reliability
Users often keep spare CR2032 cells in a range bag or safe so the laser is always ready for training or lawful self-defense.
Ideal Use Cases – Defense, Training, and Low-Light Practice
When installed on a compatible S&W K or L-frame round butt revolver, the Crimson Trace LG-308 Lasergrips can enhance: Ready Gunner+3Sportsman's Warehouse+3Adorama+3
Home and personal defense training – faster visual confirmation of muzzle alignment in low light
Range practice and fundamentals – see muzzle movement during trigger press, helping diagnose flinch and grip issues
Low-light drills – where iron sights may be harder to see, the red laser provides a clear point of aim
Always use lasers responsibly: never point at anything you are not willing to lawfully engage, and always follow universal firearm safety rules.
