LaserMax LMSG423 Red Guide Rod Laser Sight for Glock 23 Gen 1-3

The LaserMax LMSG423 Red Guide Rod Laser transforms the Glock 23 into a precision aiming platform without external modifications or holster changes. This internal laser system replaces the factory guide rod assembly, maintaining the pistol's original profile while adding instant target acquisition capabilities.

What Makes This Different

Unlike rail-mounted lasers that add bulk and require special holsters, the LMSG423 installs completely inside the frame. The system activates through ambidextrous pressure switches integrated into the frame, allowing natural grip activation without fumbling for external buttons. LaserMax's guide rod design has proven reliable through thousands of duty cycles in law enforcement and military applications.

Key Features

• Internal installation maintains original Glock 23 profile and holster compatibility
• Ambidextrous activation switches respond to normal firing grip pressure
• 650nm red laser wavelength visible to 100 yards in daylight conditions
• Aircraft-grade aluminum construction withstands +P ammunition recoil
• Pre-aligned factory setting eliminates complex zeroing procedures
• Compatible with Glock 23 Gen 1, 2, and 3 models (.40 S&W caliber)
• Automatic shutoff after 10 minutes conserves CR1/3N battery life

The LMSG423 excels in low-light scenarios where traditional sights become difficult to acquire quickly. Law enforcement officers appreciate the covert installation that doesn't telegraph tactical capabilities, while competitive shooters benefit from faster target transitions. The system maintains zero through extensive firing sessions, with the internal mounting protecting the laser from impact damage that affects external units.
