Lasermax LMSG519 Red Guide Rod Laser Glock 19 Gen5 19 MOS 19X 45

The Lasermax LMSG519 Red Guide Rod Laser for Glock 19 Gen5 Black from Lasermax is engineered to replace Glock's factory spring guide assembly with a rugged, high-intensity red laser sighting system for fast target acquisition in Glock 19 Gen5, Glock 19 MOS Gen5, Glock 19X and Glock 45 pistols. This user-installable guide rod laser requires no gunsmithing or special tools, and its unobtrusive internal design preserves grip feel and holster compatibility, while the ambidextrous on/off switch reinforces safe firearm handling. Designed for precise POA/POI alignment, the laser sits closest to the bore to maximize accuracy, with a 0.63-inch dot at 20 yards and an effective range up to 50 meters, powered by a 393 battery and delivering a 5mW red beam at 635 nm. The unit weighs only 0.76 ounces and is constructed from aircraft-grade aluminum for enduring performance in demanding conditions. Features include user programming for pulse or steady beam, automatic 10-minute time-out to prevent battery drain, and reliable operation that supports center-of-mass hits under dynamic shooting scenarios, making it an ideal enhancement for competition, duty, and personal defense applications.
