Being able to identify your target in a low-light environment has always been a challenge. The introduction of weapons mounted lights has been the answer to that challenge. The TLR-7 Pressure Control Grip Switch allows you to turn on 500 lumens of light with one hand. The grip switch is activated by the firing side hand when the support may otherwise be engaged. This light is perfect for dog-handlers, SWAT, CQB, or a mom holding her child with one hand and needing to defend her family with the other. The TLR-7 Contour Remote Pressure Controlled Grip Switch fits most Glock Gen 4 and Gen 5 models.Features :500 Lumens1.5 Hour Runtime131m Beam
