The unit replaces the factory recoil spring guide assembly, dropping in as a fully internal aiming system that leaves the grip profile, holster fit, and factory iron sight picture completely untouched.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe laser emits at a \u003cstrong\u003e520nM wavelength\u003c\/strong\u003e with \u003cstrong\u003e5mW\u003c\/strong\u003e of output, producing a vivid \u003cstrong\u003egreen\u003c\/strong\u003e beam that is significantly easier to pick up in daylight and well-lit indoor environments compared to traditional red lasers. The aiming dot measures roughly \u003cstrong\u003e0.63 in at 20 yds\u003c\/strong\u003e, with a useful range out to \u003cstrong\u003e50 meters\u003c\/strong\u003e. A user-programmable pulse or steady beam mode lets the shooter tune the visible signature to the conditions, and the distinct ambidextrous ON\/OFF switch built into the guide rod itself is accessible from either side of the frame for right- or left-handed operation.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eInstallation is straightforward: the LMS-1151G drops in place of the factory guide rod and uses the pistol's existing recoil spring. The unit is powered by a single \u003cstrong\u003e393 battery\u003c\/strong\u003e housed inside the guide rod. The housing carries a durable \u003cstrong\u003eblack\u003c\/strong\u003e finish that blends with the factory slide, and at just \u003cstrong\u003e0.76 oz\u003c\/strong\u003e the unit adds essentially no weight to the firearm. Because the laser is factory-aligned, no user adjustments are required after installation, making it a true drop-in sighting upgrade for full-size Glock duty and defensive pistols.\u003c\/span\u003e\u003c\/p\u003e","brand":"LaserMax","offers":[{"title":"Default Title","offer_id":54996052541762,"sku":"90164","price":302.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/7921\/5682\/files\/hires_8482de00-8059-46b0-886c-ddae8e0ad64a.png?v=1784316047","url":"https:\/\/centerfiresystems.com\/products\/lasermax-lms-1151g-green-guide-rod-laser-for-glock-20-20sf-21-21sf-gen-1-3-black","provider":"Centerfire Systems","version":"1.0","type":"link"}
