The LaserMax LMSG41151G Guide Rod Laser is a green laser sighting system built into a replacement spring guide assembly for Glock 20, 21, and 41 Gen4 pistols. Unlike add-on laser modules, this guide rod laser integrates directly into your pistol's recoil spring assembly—eliminating bulk, preserving holster compatibility, and placing the laser as close to the bore as possible for superior point-of-aim accuracy. The 5mW green laser (520nM wavelength) pulses for rapid target identification in low-light conditions and tactical scenarios, while the rugged aluminum construction and genuine Wolff springs ensure reliability through thousands of rounds.
Installation is straightforward: the unit replaces your factory spring guide assembly without gunsmithing or special tools. The ambidextrous ON/OFF switch is positioned to reinforce safe handling habits, and the internal design means your favorite holsters and grips work unchanged. This is purpose-built for shooters who want a dedicated aiming aid without compromise—whether you're running drills at the range, preparing for defensive carry, or training with your duty pistol.
LaserMax's alignment guarantees mean you can trust your POI from the moment you install it. Green wavelengths cut through dust, smoke, and ambient light better than red, making this laser especially effective in dynamic shooting environments where fast target acquisition matters.
| Brand | LaserMax |
| Model | LMSG41151G |
| Compatibility | Glock 20 Gen4, Glock 21 Gen4, Glock 41 Gen4 |
| Laser Type | Green (520nM wavelength) |
| Power Output | 5mW |
| Construction | Aircraft-grade aluminum with genuine Wolff springs |
| Installation | Replaces factory spring guide assembly; no special tools required |
Yes. The guide rod laser integrates into the recoil spring assembly inside the pistol, so it doesn't extend beyond the slide or interfere with standard holsters, grips, or aftermarket parts. Your existing setup will work unchanged.
Green laser light (520nM wavelength) is more visible to the human eye in bright daylight and smoky/dusty conditions, making it faster to acquire and track targets. This 5mW green laser is particularly effective in dynamic shooting scenarios and low-light training environments.
No. The LaserMax guide rod laser replaces your factory spring guide assembly as a drop-in component. Standard disassembly tools are all you need; no special gunsmithing is required.
LaserMax guarantees alignment on this unit, meaning your laser point should correspond reliably to your center-of-mass impact once installed. The proximity to the bore maximizes accuracy.
