Lasermax Internal Laser Sight - For Glock 39 Gen 1-3 Red
The LaserMax Internal Laser Sight for Glock 39 Gen 1-3 is a red laser system built into the guide rod of your pistol, giving you a compact aiming tool without adding bulk to your slide or frame. If you shoot a Gen 1, Gen 2, or Gen 3 Glock 39, this sight installs internally where it's protected and always ready. Internal laser sights appeal to shooters who want quick target acquisition at close range, backup aiming in low light, or a training aid for dry fire practice without the commitment of permanent slide modifications.
LaserMax lasers come from the factory with their beam already aligned to your gun's point of impact, so you skip the hassle of zeroing a sight that might drift after installation. That permanent alignment design means once you install it, the laser point stays true—a real advantage when you're relying on it for critical moments.
Internal laser sights live inside the gun, which keeps them out of sight and away from snags, but also means installation requires disassembly of the guide rod. This is a straightforward job for most shooters, but if you're not comfortable taking your pistol apart, a gunsmith can handle it. The red laser is visible in most indoor and outdoor lighting, though it won't compete with bright daylight like some green lasers can.

Frequently Asked Questions
Will this laser work with my Glock 39 generation?
This LaserMax laser is built specifically for Glock 39 frames in Gen 1, Gen 2, and Gen 3 configuration. It will not fit Gen 4 or newer Glock 39 models. Double-check your pistol's generation before ordering.
Do I need to zero or align this laser?
No. LaserMax internal laser sights arrive from the factory with the beam already aligned to your pistol's point of aim. That alignment is permanent and won't shift, so installation is your only step.
How do I install an internal guide rod laser?
Installation requires disassembling your Glock's guide rod and replacing it with the LaserMax unit. This is a straightforward field-stripdown task for most shooters, though a gunsmith can install it if you prefer.
Is a red laser visible in daylight?
Red lasers are visible in indoor shooting, dim conditions, and overcast outdoor light, but will be harder to see in bright sunlight. If you need daytime visibility, a green laser is generally a better choice, though this product uses red.
