Reviews & Ratings for SureFire X300 Tactical Handgun / Long Gun LED Weaponlight w/ Universal Mount, 170 Lumens — 45 reviews — Page 1

solid and reliable light, however it does NOT fit on my glock 17 gen 4, glock 31 c or p226 elite. ...left me a bit confused.
also, it is pretty difficult to put on ans standard picatinny rail. very tight.

This light is awesome. It is very bright and easy to actuate. However, if you have a sig p226 like me, you will have some trouble fitting it on your gun. You must use the universal mount, not the picatinny. The picatinny rail on the p226 is not in spec. Overall, I am happy with my purchase.
Pros: Very Bright and easy to operate
Cons: does not fit well on a sig p226

The X300 is the best light for the AR platform I have used. Momentary on/off and turning on indefinitely are intuitive and easy to perform. The light has an excellent focused central cone of light that is useful to ~150 yards, while peripheral illumination is also very good. Compared to its main rival - the TLR Streamlight - this is more combat effective in terms of the illumination blinding an aggressor (again, there is plenty of peripheral illumination too). Durability goes without saying in a Surefire product. I own 2 of these lights, and they fit very tight on a mil-spec picatinny rail (factory Colt), so sliding it on and off the rail can be a little difficult. But once it's on, it's not going to come off by accident. It's also a lot more compact and lightweight than the "full flashlight" alternatives that don't work any better than this. There isn't another site I would put on a rifle over this one (other than maybe the brighter x300 ultra, which I have never had a chance to use).
Pros: very bright, easy to operate, durable, compact and lightweight
Cons: initial mounting on rail can be difficult

Had some trouble attaching to my rail, but once attached worked as intended.
Pros: Functional, reliable, solid
Cons: Difficult to attach to picatinny rail

My agency issued these to all of us to be mounted on our Gen4 Glock 22's. Can't say enough about how well it works and the performance. If you have the $ to lay out, its definitely worth it. We fire a full 50 round qual course in low-light and the light functioned great. I
Pros: extremely bright, functions well even with multiple rounds fired

I choose Surefire for one reason, reliability,my life can depend it when I need it.
Pros: Reliable,lifetime warranty, easy to use.
Cons: Expansive

Rugged reliability and performance. So far so good.
Pros: works as advertised
Cons: pricey

I have the surefire x300 mounted on my glock 17. From time-to-time I will throw it on my AR. It is very bright and very durable. I have dropped it on multiple occasions and it works just like it should. If you have the cash, it is worth. However, if money is tight, I would recommend the Streamlight TLR.
Pros: Durable, Bright
Cons: Price

I have owned a X-200 for years, and it was a really tight fit until it had been installed and removed several times. The X-300 will not slide on the Surefire rail(HK USP Compact) that accepts the X-200. It's back in the box until I decide to have another go at it.
Cons: Won't slide on Surefire's own rail.

Fits on snug, but not so much that you can't remove it. Activation switch for "constant on" works up or down, which is nice. That way the device conforms to your style, not forcing you to learn to activate it in an odd or uncomfortable way. Also pushing with the trigger finger (or any other, I suppose) you can temporarily activate light. This is also a nice feature. It seems like a lot of thought went into this device. Although expensive, it is a wonderful accessory. I'm very glad I purchased it.
Pros: light weight
Cons: low holster choices
