Surefire X300 Ultra Review

I've had the Surefire X300U for a while now but never did a review; so here goes... 

Pros:

-500 lumens with a good balance of throw/spill

-Uses two 3V CR2 lithium battery.

-Comes with a 1913 and universal mount/insert so it'll fit most modern rail systems to include rifles

-It handles recoil well.  I've used the light on my G20 with hot ammo as well as on an AK with 0 issues from the recoil

-Rocker switch can be used for temporary and constant on modes

-Great warranty

-4oz weight

Cons:

-1.5 hours of constant on.   The old battery life vs lumens issue is at play here.

-It's extremely tight when mounted on some guns.   This could be a pro for some but, on my Glocks for example, the light is seemingly stuck on the gun and I've had to tap it with a rubber mallet while pulling down the tabs before to get it off.    

-Price.  No getting around it---it's expensive.   It generally runs around $210-240.

Summary:

It's an excellent all around weapon light.   It's versatile, bright, and durable.  The big question is whether or not it's worth the money.  Only you can answer that ultimately I suppose.

Here's a video showing the light in use on several guns, a comparison with some different lights, some night shooting, and a discussion of the pros/cons of the light:
