How to Choose the Best Light for Glock 43x
Selecting the right light for your Glock 43x involves considering several key factors:
Brightness:
Consider the lumen output. Higher lumens provide better visibility but may drain the battery faster. For most defensive purposes, 300–600 lumens is usually sufficient.
Size and Weight:
Since the Glock 43x is a compact handgun, the light should not add excessive bulk or weight. Look for lightweight options that maintain the gun’s balance and ease of handling.
Battery Life:
Evaluate the runtime of the light. Rechargeable batteries can be convenient, but having a reliable battery life is crucial for ensuring your light is ready when you need it.
Mounting System:
Ensure the light can be securely attached to your Glock 43x. Quick-detach systems are beneficial for easy removal and reattachment.

Check for water and impact resistance to ensure the light can withstand harsh conditions and potential drops.

Look for lights with intuitive controls that allow for easy activation, especially in high-stress situations.
