The Sight-Line is a forward-facing laser that mounts to most pistols with a Picatinny or Weaver-style rail. The laser includes a unique mounting system, allowing you to position the large ON/OFF buttons so they are easy to reach. The laser has a wide adjustment range to line up with most caliber, ammo, and iron sight configurations, providing fast and precise aiming in low light. Whether used for practice at the range, home defense, or concealed carry, the TRUGLO Sight-Line laser is a powerful enhancement to your handgun in a compact and lightweight form factor.
