Buying Guide
Key factors to consider when selecting a Glock 43X light include compatibility, brightness, beam characteristics, and power options. First, verify whether your pistol uses a rail, MOS, or no rail. Some lights are designed exclusively for railed configurations or require specific mounting kits, while others are compatible with non-rail models. Next, brightness and beam distance influence field use: higher lumens and longer throw help identify threats at greater distances, but can reduce battery life. For concealed carry, a compact, lower-lumen option may suffice for close-quarters use. Integrated lasers add aiming assistance but require alignment with your optics and shooting style. Rechargeability offers convenience, but consider the availability of spare batteries and the ability to replace batteries without removing the light.
- Compatibility: rail, MOS, or non-rail Glock 43X configurations
- Brightness vs. battery life: 100–1000+ lumens, beam distance
- Attachment system: tool-free clamps, mounting kits, ease of detachment
