SureFire X300U-B Reviews

The Best Pistol Light

By Spencer
Rated 5 out of 5
Date: 2025-02-13

I use SureFire X300's on all my pistols with light rails. The B is best for steel frame guns and A for polymer. B&H price matched this too from a competitor. Highly recommend!

Super Bright Light

By Paul
Rated 5 out of 5

If you want a super bright light with focused light in the center and plenty of light on the periphery, this is the one. The only thing that takes some getting used to is the pointedness of the switch you depress to activate the temporary on/off feature. I decided it must be designed with the point for so that you know your finger is on it when using gloves. Also, the pin that is to be inserted in the battery compartment's latch does not go through and stay secured on both sides of the catch - only one side. This is poorly designed. When I did some research online to determine if I simply was not inserting the pin correctly, I found other people encountered the same issue. But, as I also found online, you don't really need the pin (the purpose of which, according to SureFire, is to make sure the battery compartment's latch does not accidentally come open) because, once you have it affixed the light to the pistol, the battery compartment's latch abuts the trigger guard, making it impossible for the latch to inadvertently come open. I plan to purchase another one of these soon.
