Crimson Trace LG-489 Laserguard 5mW Red Laser for S&W M&P Shield & M2.0 (Excludes EZ & Plus) - 50 ft Range, Black Finish

The Crimson Trace LG-489 Laserguard is a red laser sight purpose-built for the Smith & Wesson M&P Shield and M2.0 concealed carry pistols. If you carry a Shield for personal defense, this trigger-guard-mounted laser activates the moment you grip the gun naturally—no fumbling with buttons or switches. The laser comes sighted at 50 feet and is fully adjustable for windage and elevation, so you can zero it to your specific firearm and shooting style.

Installation is straightforward and requires no gunsmithing. The LG-489 mounts cleanly to your Shield's trigger guard with a solid polymer housing and rubber overmold activation pad that's built to take daily carry wear. At 5mW output, the red dot is visible in most indoor and outdoor lighting conditions, and the dot size runs approximately 0.50 inches at 50 feet—tight enough for precision aiming at typical defensive distances. Battery life exceeds four hours of continuous use, and the sight accepts either one 1/3N lithium battery or two 357 silver oxide batteries, giving you flexibility in what you keep in your range bag.

This is a tool for shooters who want their defensive pistol to work faster and more intuitively in a critical moment. The Instinctive Activation system means the laser is already on when your hand is on the grip, eliminating the lag between drawing and aiming. For training, dry practice, or building muscle memory with your carry gun, that edge matters.

No. The LG-489 is designed for the standard M&P Shield and M2.0 only. It does not fit the EZ or Plus variants.

How does Instinctive Activation work?

The laser turns on automatically when you grip the pistol in your normal firing grip, thanks to pressure on the front activation pad. You don't need to manipulate a button or switch—draw and the laser is already active.

What batteries do I need?

You can use either one 1/3N lithium battery or two 357 silver oxide batteries. Battery life exceeds four hours of continuous operation.

Can I adjust the laser after installation?

Yes. Windage and elevation are user-adjustable so you can zero the laser to match your point of aim. The sight ships factory-sighted at 50 feet as a starting point.
