Why Buy The New Streamlight TLR 7 SUB - Just like the popular TLR 7A Flex with all the great features & same performance, the Sub model is made to fit on subcompact slim handgun frame.

Crimson Trace LL 803 Laserguard - Fastest Activation Switch

Why we picked the Crimson Trace 803 as our second pick for the G43. Similar to the Streamlight TLR 6, but the instinctive light activation is unbeatable for enhanced 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.

Overall the CT LL 803 is our second-best weapon light and laser combo for the Glock 43 series handguns, backed by 3 years limited warranty.

Streamlight TLR6 - Smallest Size

Glock 43x with streamlight TLR 6

Why we picked this one - The Streamlight TLR 6 is the only light that mounts on the trigger guard of the non railed Glock 43 and 43X. .

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. 

Simple Battery Replacement - Replace the battery without taking the sight off the gun. No re-zeroing or finding tools required

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

Common FAQ

Instinctive Light Activation VS Manual

Instinctive light activation activates the light immediately once the shooter grip the gun to eliminate any poor gross motor skill that might occur during stressful situations.

This feature ensures the light or laser ALWAYS comes on no matter how high the shooter's adrenaline is.

So why use the manual control then?

A manual operated weapon light toggle switch gives the shooter full control over the light. Not every situation requires a light, so a trained shooter can really appreciate this type of light.

Disvantages Of Light Bezel Sits Flush With The Muzzle

The disadvantages is apparent in up close personal defensive situations.

  • Flush muzzle fit light doesn't keep muzzle & slide cleared when pushed against something point blank. It means it could slightly push the slide assembly back and get out of battery easily
  • Every shot will leave carbon residue to the weapon light sitting close to the muzzle. 

Learn how to keep the light lens clean after the range session is important habit for conceal carry people.

Maybe using a Glock 19 is a better choice? We also have a G19 Weapon Light Buyer's Guide on our site you can check out.
