Description
The LaserMax CenterFire is a trigger guard mounted light and laser system built to blend seamlessly with your Glock 42 or 43. What sets it apart is the GripSense technology that detects your firing grip and activates the laser and light automatically without requiring you to change how you hold the gun. Unlike traditional weapon-mounted systems that demand button presses or grip adjustments, this one gets out of your way.
GripSense Activation Works Your Way
The system uses capacitive sensing technology similar to smartphone screens. When your middle finger indexes the trigger guard area, the sensor activates your choice of light, laser, or both. It works just fine with gloves on too. If you prefer manual control, you can disable GripSense and use the ambidextrous push-button switches instead. The real benefit here is that you've got options. Some situations call for instant-on, others require more deliberate control, and this gives you both without swapping gear.
Light and Laser Specs You'll Appreciate
The mint green LED light delivers 100 lumens, which is bright enough for target identification in dark rooms and home defense scenarios. The 520nm green laser sits at 5mW output and is programmable for either steady or pulsed modes depending on what you need. Both the light and laser adjust for windage and elevation with tool-free battery access on the side. The whole unit weighs just 1.5 ounces and uses a 1/3N lithium battery that comes included with the package.
Built to Stay Put
The rounded, blended design looks factory and sits close to the gun, making it easy to draw from concealment. It mounts directly to the trigger guard without any permanent modifications, so you can remove it if needed. The ambidextrous controls work equally well for left and right-handed shooters. It's water resistant and built from fiberglass-reinforced nylon, giving you a tool that'll hold up through range sessions and carry use.

Frequently Asked Questions
How does the GripSense technology actually activate the light and laser?
GripSense uses capacitive sensing similar to smartphone touchscreens. A detection zone sits under the trigger guard where your middle finger makes contact. When you establish a firing grip, the sensor detects this and activates your selected light, laser, or both instantly. You can also disable this and use the manual push-button switches if you prefer.
Will the GripSense work if I'm wearing gloves?
Yes, GripSense functions reliably with gloves on. The system detects your hand proximity at the trigger guard area, so tactical gloves won't interfere with activation. This makes it dependable for cold weather carry or tactical training where you might be armed up.
What battery does this use and how long does it last?
The CenterFire uses a single 1/3N lithium battery, which comes included with the unit. Battery life depends on how often you use it and which features you have active. The external battery door allows quick replacement without removing the unit from your gun.
Can I install this myself without gunsmith help?
Installation is straightforward and requires no permanent modifications to your Glock. It mounts to the trigger guard with included screws that clamp the unit in place. Most owners report taking just a few minutes to install and sighting it in. No permanent damage means you can remove it anytime if needed.
