The Streamlight TLR-8 Sub is a compact weapon light and laser combo built for subcompact and compact handguns with 1913 short rails. If you carry a modern micro-compact—whether a Glock 43X/48 MOS, SIG P365, Springfield Hellcat, or any of a dozen other popular platforms—this light solves the real problem: how to run effective illumination and aiming reference on a gun that doesn't have room for full-size gear. The TLR-8 Sub clips on securely without fuss and gives you white LED light, a laser (your choice of red or green), and enough versatility to support your actual shooting style.

The light runs at 500 lumens with a 141-meter beam, delivering real visibility in low light without wasting battery life. One CR123A lithium battery powers the light for 1.5 hours of continuous use, or the laser for 60 hours if you're running it without the LED. Streamlight included ambidextrous rear paddle switches you can swap to match your grip preference—left, right, or dual-pad config. A safe-off bezel prevents accidents, and the user-enabled strobe gives you another tool if you need it. The rail clamp grips tight but detaches clean, no muzzle-in-front-of-your-hands fumbling. Build quality is durable anodized aluminum, and the whole package weighs just 2.77 ounces and stretches 2.51 inches—tight enough to stay true to the subcompact platform you chose.

Water resistance (IPX4) handles normal carry and training conditions. Battery is included. If your subcompact has a 1913 short rail or you own one of the directly compatible models listed, this light closes a real gap between "just a gun" and a practical defensive or tactical platform.
