Want to add a serious advantage to your Glock? This Lasermax LMS-1141G is a green laser sight that mounts right inside your pistol's guide rod—no gunsmithing needed for Gen 1-3 models like the Glock 17, 22, 31, and 37. It's brand new, unused, and comes in its original packaging. The green laser is way easier to see than red, especially in daylight. It runs on a common 393 silver oxide battery. Made in the USA by LaserMax, known for quality. This isn't some cheap accessory; it's a precision tool that integrates cleanly without altering the gun's profile. Perfect for tactical training, home defense setup, or competition. The guide rod replacement installs in minutes, giving you an instant, accurate aiming point. Great for low-light scenarios or just improving your target acquisition speed. Comes with everything you need. If you're looking to upgrade your Glock with a reliable, high-visibility laser from a trusted brand, this is the one. UPC: 0798816542608.
