Why Use This One? This is our pick, the Crimson Trace laser for Glock 43X light no rail option. It's similar to the Streamlight TLR 6, but it features the instinctive light activation system to assist poor gross motor skill under stress.

Also works for G42, and G48.

The light produces up to 150 Lumens, which is 50% more lumens than the TLR6. The 5mW Class 3R red laser makes improvised shooting more accurate and fast. All of these features are ran under just 1 CR2 battery, which lasts about 2 hrs.

Super Low Profile - The CT LL 803 mounts on the frame securely around the trigger guard, and tighten down by a few screws to hold it in place. (Use 0.05 wrench size for installation)

Instinctive Light Activation - Active the device simply by gripping the gun! yes just that easy without worry of where the toggle switches are in the dark or with poor motor skills.


  • Instant activation when gripping the gun
  • Very bright lumen output & flood
  • USB Rechargeable battery


  • Light turns on when gripping the gun
  • Installation takes time

Streamlight TLR 6 - Smallest Size

Why we picked this one - The Streamlight TLR 6 is the only Glock 43X light no rail model. It goes straight onto the trigger guard of the gun frame.

Contoured Body Profile - The shape of the TLR 6 blends in with the profile the G43 around the trigger guard. It fits flush with the muzzle and it doesn't snag on anything when holstering.

Fast Aiming - Aim fast with the laser light without taking eyes off the target or aligning iron sights. 

Ambi Control - Activating the light from either side simply by pressing the push-button. Works for lefties and righties.


  • 100 Lumens (2000 Candela)
  • 80 meters throw
  • No Strobe
  • 1.12 oz

The lumen intensity isn't the best compared to what are on the market today. We highly recommend getting options 1-3 and mount it with the Recover Tactical GR43 Picatinny Adapter Rail


  • Activation felt easier than it looks
  • Very streamlined design for CCW
  • Very bright for its size


  • Difficult to install
  • Not for mid range use
  • Uninstallation required to swap battery
