Glock 42 Red Guide Rod Laser Performance
The Glock 42 red guide rod laser is designed specifically for use in Glock 42 pistols. The LMS-G42 replaces the factory recoil spring guide assembly with a rugged, precision-engineered laser sighting system built for dependable performance.
This internal design positions the bright red 5mW aiming point closer to the bore than external laser systems, supporting consistent alignment and improved target acquisition.
Precision Engineered Internal Design
Constructed with premium raw materials, including a stainless steel tube, the Guide Rod Laser delivers superior reliability under demanding conditions.
Its rugged internal configuration does not restrict holster compatibility or alter grip selection, preserving the firearm’s original ergonomics.
The system is factory-aligned to stock ballistics for guaranteed POA/POI accuracy.
User Installation and Programmable Modes
Installation is straightforward and does not require gunsmithing or special tools.
Additional performance features include:
- Programmable steady or pulsing beam
- Distinct ambidextrous ON/OFF switch
- 5mW high-intensity red laser output
The ambidextrous activation reinforces safe handling while allowing quick access for either hand.

Great. I tried ordering from optics planet. 3 weeks after the initial order they refunded my money without telling me. I ordered my laser from laser max and 4 days later it was at my house. Thank you.

After installing the Laser-Max Guide-Rod Laser system on my Glock 42 .380. The accuracy was spot on! The fit feel and finish is impeccable. Absolutely thee best if not the only guide rod laser I would use in my firearms. This is a MUCH BETTER alternative to the bulky Piccadilly rail style Laser’s, that force you to buy modified holsters for EDC. Absolutely love it!

I like that it doesn’t take up additional space because it fits inside the current space in my Glock.
