Description
The Viridian E Series for the M&P Shield 9/40 is a purpose-built laser sight designed by people who understand what concealed carry really means. This isn't a universal laser that sort of fits anything. It's engineered specifically for your Shield, which means it mounts cleanly on the trigger guard with minimal bulk and actually looks like part of the gun rather than bolted on as an afterthought.
What makes this red laser different is the power output. Viridian designed it to deliver the brightest red laser legally available for civilian use. At 25 yards in daylight and out to a mile at night, the dot stays visible when you need it most. The trigger guard mounting keeps everything compact and accessible, perfect for quick target acquisition in situations where speed matters. Ambidextrous buttons mean both right and left-handed shooters can activate the laser naturally without changing their grip.
Performance in Real-World Conditions
Battery life hits the practical sweet spot. You get 6+ hours of constant laser time per charge, and the automatic 5-minute shutoff protects against dead batteries from accidentally leaving it on. The windage and elevation adjustment system stays put once you dial it in at the range. Real users report it holding zero through hundreds of rounds and daily carry, which tells you this isn't fragile.
Design Built for Concealed Carry
The included Kydex holster isn't just an afterthought accessory. It's handcrafted in Minnesota specifically for the M&P Shield with the E Series laser mounted. Inside-the-waistband, right-handed configuration means the laser-equipped pistol stays secure and snug during your day. At just 0.78 ounces, the laser itself doesn't add noticeable weight. High-strength thermo-molded polymer housing gives you durability without the bulk that turns concealed carry into printing.

Frequently Asked Questions
Does the E Series fit the M&P Shield Plus or Shield EZ?
No. The E Series red laser is specifically designed for the original M&P Shield 9mm and .40 S&W models. It does not fit the M&P Shield Plus or the M&P Shield EZ, as those models have different trigger guard dimensions. Always verify compatibility before purchasing to ensure proper fit.
How long does installation take and is it difficult?
Installation is straightforward and takes just a few minutes. The laser splits into two halves that clamp around the trigger guard, then you secure them with the included screws using the provided driver. Most owners report having it zeroed in at the range within minutes of installation, so there's no gunsmithing required.
How does the red laser compare to a green laser for this platform?
Red lasers like the E Series are effective in low-light conditions and at night. Green lasers are more visible in bright daylight but consume battery power faster. The E Series red laser offers solid all-around performance, good battery life, and lower cost, making it a practical choice for everyday concealed carry. The choice between red and green ultimately comes down to your primary shooting environments.
Will the laser sight work with my existing holsters?
The E Series adds bulk to the trigger guard area, so most standard Shield holsters won't accommodate it. The included Kydex holster is specifically molded for the Shield with the laser mounted. If you use other holsters, you'll need to verify they can fit the laser-equipped gun or purchase a separate laser-compatible holster.
