Streamlight 4011297-SSI TLR-6 Subcompact Gun Mounted Light with Red Laser FDEB Color - Multi, N/A

This light is great for close in work and defense on a Glock 43. The light is not a blinding light, it will do the job with identifying a threat in your home or 10-15 yards out. Not the kind of output to be considered a combat light, but a G43 really isn't a combat pistol. This light serves it purpose to provide light at pistol fighting distance, nothing more. The laser is bright and crisp, easy to see with the white light on, and easily adjustable for windage and elevation. The on/off switch is easy to press from either side and I do not worry about accidentally activating it. Install requires the light to be unsrewed and it splits in half, goes over your trigger guard and is snugged back up by the screws. Once tightened down, it stays in place and holds the laser's zero nice and tight. Holsters are available for this light so it's not hard to find a carry solution for it. I find this light to be a great price for what it does and although I have not had it for very long, it seems well built and having owned many streamlight products over the years, I expect it to work how and when it should.

Great product. Easy to install and sight in. Holds tight to lower and feels like part of the gun after installation. Well designed in that on/off button is easily operated and batteries can be changed without having to remove entirely. Bright light and laser that stays on target after hundreds of rounds.

Fits perfectly on Glock 42 model as if it came from the factory. Fde color matches perfectly. Laser is pretty strong & the light is bright.

Fits very snug and secure. Very bright. A common light, so finding holsters that fit with it was easy

Streamlight has always made reliable and bright flashlights and the brightness of this light is no different. The fit and finish of this light fits perfectly and snuggly to the trigger guard and frame. I really like having the option of light only, laser only, or light and laser together. I like more lights, you do not have to remove it from your weapon in order to change out the batteries. The only complaint would be that the light comes in a dark brown FDE. I had my Glock 43 Frame cerakoted FDE and the TLR-6 was a much darker brown. I had to have the TLR-6 frame cerakoted to match the gun frame. Other than that, this is definitely the best option for the Glock 42 or 43 as it's designed to fit both models.
