SKU: LVLMS2291G
MPN: LMS-2291G
The LaserMax LMS-2291G is a green guide rod laser built specifically for the SIG Sauer P228 and P229. Instead of clamping onto a rail or replacing grips, this unit replaces the factory recoil spring guide assembly, putting the laser inside the pistol where it adds zero bulk and imposes no holster restrictions. The high-visibility green beam sits close to the bore axis, which keeps point-of-aim and point-of-impact tracking consistent across the gun's effective range. For P229 owners who carry concealed or run a duty rig and want a sig p229 laser that disappears into the frame, this is a direct internal upgrade.
LaserMax machines the body from aircraft-grade aluminum and pairs it with genuine Wolff springs, so the unit functions as a working recoil spring assembly while housing the laser. The green diode runs at 520 nm with output under 5 mW, placing it in the Class 3R visible laser category. It projects roughly a 1-inch dot at 10 yards with a maximum useful range of 20 yards. Activation is ambidextrous through the takedown lever, and the beam is user-selectable between pulse and steady modes. The assembly is waterproof and ships factory-aligned for guaranteed accuracy, so installation requires no gunsmithing. Power comes from an LMS-3x393 silver oxide battery stack rated for one hour of continuous run time. Finish is matte black throughout.
This laser suits P228 and P229 shooters who want faster sight alignment in low light without changing the gun's external profile. Because the mounting is internal, every holster that fits the bare pistol still fits with the laser installed, and the green wavelength reads faster than red for most eyes in daylight and dusk conditions. Owners install it themselves in minutes by swapping the recoil spring assembly. It carries a five-year limited warranty to the original purchaser. Pair it with a weapon-mounted setup or browse our broader selection of laser sights and pistol sights to round out your handgun.
Yes. This guide rod laser is engineered for both the SIG Sauer P228 and P229. It replaces the factory recoil spring guide assembly inside the slide, so it works across both platforms that share that assembly design.
No. The unit is user-installed and ships factory-aligned. You field-strip the pistol, remove the factory recoil spring guide assembly, and drop in the LaserMax assembly in its place. No tools beyond standard takedown and no gunsmithing are required.
The green 520 nm beam is more visible to the human eye than red, especially in daylight and dusk conditions. That visibility translates to faster target acquisition. This unit projects roughly a 1-inch dot at 10 yards with a maximum useful range of 20 yards.
Yes. Because the LMS-2291G mounts internally and replaces the recoil spring guide, it adds no external bulk. Any holster that fits the bare P228 or P229 will still fit the pistol with this laser installed.
Activation is ambidextrous through the pistol's takedown lever. The beam is also user-selectable between pulse and steady modes. The LMS-3x393 silver oxide battery stack provides about one hour of continuous run time.
