The Streamlight TLR-6 for the S&W M&P Shield is an ultra-compact weapon light that enhances firearm functionality with reliability and ease of use, delivering a 100 lumen white LED output through a parabolic reflector for a balanced beam and peripheral illumination. Built from durable, impact-resistant materials and featuring a glass lens sealed with shock-resistant gel, it withstands the rigors of everyday use, and its IPX4 water resistance keeps performance intact in wet conditions. An ambidextrous on-off push-button switch enables quick activation, while tool-less battery replacement allows you to swap the two included CR1/3N lithium batteries without removing the light from your firearm. With a run time of about one hour and a beam distance of up to 89 meters, this compact light is ideal for identifying potential threats in low-light scenarios. Weighing 1.27 ounces and measuring 2.30 inches in length, it secures to the rail and trigger guard of the S&W M&P Shield, making it a dependable choice for personal defense or tactical applications.
