Introducing the leanest, brightest, tightest X5L, ramped up to evaporate darkness, subdue opponents and optimize a full-sized pistol like nothing else. The blinding 154 lumen taclight is bigger and brighter, with beam intensity and explosive strobe that give aggressors nowhere to hide. The brilliant Viridian green laser is visible day or night, indoors and out. The leaner, aluminum-body profile fits your pistol as tight as a tattoo. An arsenal of custom modes lets you pre-program your tactics, then adjust on the fly to keep the advantage on your side. You put a lot of thought, time and training into mastering your skill with weapons and tactics. The ultimate X5L makes sure it pays off when it counts.
