Phenomenal wml - SureFire MasterFire Ultra High Output LED Weapon Light, Red Laser Weapon Light

The new SF Masterfire series of lights are a good, incremental improvement over their respective predecessors. Because of the locking mechanism being machined in the front of the light, the already stout bezel has been beefed up. The X400UH has better output than my X400U, and is overall a better light. Holster figment can be problematic, due to the increased bezel diameter; however, if you have a kydex holster for an X400U, 5 minutes with a hair dryer and the X400UH will drop right in.
