Rated at 100 lumen, I wasn't entirely sure the Streamlight TLR-6 with red laser would throw enough light. After installing this onto my new P365 (manufactured on 26 June 2020), my concerns vanished. It provides a satisfactory amount of light ... and to the degree that makes me wonder if the claim of 100 lumen is a bit low. The TLR-6 is sturdy and for most people should be easy to install with the included (very, very small) Allen wrench. My TLR-6 came with the battery compartment door unattached, likely caused during shipping because the box had clearly taken a beating and was in sad shape. However the battery door, the very small hinge sleeve and hinge pin were in the box and I was able to reassemble it. As mentioned by other reviewers, the light only, light and laser, or laser only feature is nice and the unit "remembers" your last selected type of illumination without fail. The red laser is quite bright, but not as distractingly bright/intense as a green laser can be. I use a green laser mounted to my camera's hot shoe in astrophotography as a pointing guide at celestial objects as it provides a visible beam of light from the camera to the target... not exactly what you want on firearm. In some outdoor, bright sunlight situations, the red laser might not be all that effective, but I intended the laser to be used in dark situations anyway. As such, the red laser is essentially perfect. I tested the laser by pointing it at targets far, far beyond the effective range of a micro-compact pistol like the SIG P365 and it functioned exactly as desired. Windage and elevation adjustments to the laser were easily accomplished. I haven't a single significant complaint with the TLR-6. That said, as the TLR-6 requires two CR 1/3 N batteries (two were included, of course), you might want to locate a reliable source for fresh batteries. I had to visit three stores to have some spare batteries on hand. Could the light be brighter? Sure, I wouldn't complain it was, but it's more than sufficient as is. Some method of storing, or attaching, the tiny Allen wrench to/in the light itself would be a nice touch as well. For now, it resides at the bottom of a credit card slot in my wallet. In that way, I've always got it with me... and that Allen key, as I've said, is very, very small. Overall, I'd absolutely recommend the Streamlight TLR-6 to anyone wanting a rail mounted light/laser combination for use with a micro-compact pistol like the SIG P365, Springfield Armory Hellcat or various other micro-compacts.
