LaserMax LMSG417G Guide Rod Green Laser for Glock 17/34 Gen4 - 5mW, 532nM, 20yd Day/300yd Night Range, Aluminum

The LaserMax LMSG417G Guide Rod Green Laser for Glock 17/34 Gen4 is a streamlined alternative to mounted laser sights and tactical lights that add bulk to your carry or duty gun. This internal guide rod laser replaces your existing spring guide rod, meaning there's nothing sticking out from the frame—no extra holster requirements, no additional controls to fumble with in a high-stress moment. What you get is a solid green laser (532nM wavelength, 5mW output) that's there when you need it, invisible when you don't.

The green laser is visible out to roughly 20 yards in daylight conditions, extending to 300 yards at night when ambient light drops. That makes it genuinely useful for close-quarters work and home defense while also capable at longer distances in low-light scenarios. The aluminum construction keeps weight minimal and durability high—this isn't a fragile add-on, it's built to function in demanding conditions, which is why LaserMax's design has earned trust among professional users over more than two decades.

Installation is straightforward: it's a drop-in guide rod replacement for Gen4 Glocks 17 and 34, so you're not dealing with receiver modifications or permanent alterations. You maintain full compatibility with your existing holsters, ammunition, and handling characteristics. The laser activates when you grip the gun, so target acquisition and sight picture alignment happen naturally as part of your draw and presentation.
