A- pretty good gun light combo - Steiner TOR Fusion Laser Sight

I own 4 of these - 2 on G45s and 2 on G19s. They live in Safariland 6378USN-283-701 holsters and the fit is fine. I run mine in light + laser mode all the time. Changing modes is a bad plan when bad things are happening and training in the mode you will use when bad things happen is advisable. I don’t use the activate on draw feature. There are situations where you don’t want your light on. The switches are big and tactile. The adjustment range for zero is more than adequate. The adjustment screws ARE loose and require a very small (no drips) amount of threadlocker (blue) to be applied to the threads. Zero the laser, count turns as you back the screw out, use a toothpick to apply only enough threadlocker to wet the threads and reinsert with the same number of turns you used to remove. Screw is tiny, be careful. You’ll have 2-3 minutes to adjust before the threadlocker sets up. I’ve put hundreds of rounds through each of those guns and zero holds up on all of them. Light is bright enough, laser is great unless you’re in bright daylight. In this price range you won’t find a better combo IMO. A- is for the threadlocker.
