The HiViz LiteWave S&W M&P Shield Rear Sight – Green Fiber Optic (Model MPSLW11, UPC 613485589214) is a high-visibility, all-steel replacement rear sight designed to give your Shield a faster, brighter sight picture in any lighting. Built around HiViz’s innovative LiteWave® fiber-optic technology, this rear sight drops into your factory dovetail and dramatically improves your ability to pick up the front sight and get on target quickly. hivizsights.com+2Black Market Arms+2
Built for the S&W M&P Shield, Shield Plus & M2.0
This HiViz LiteWave rear sight is purpose-built for the Smith & Wesson Shield family:
If you’re running a Shield as an EDC pistol, home-defense gun, or range workhorse, this sight is made to be a factory-height, direct replacement for the stock rear sight—no oddball POI issues or strange sight picture. hivizsights.com+1
LiteWave® Fiber Optic – Bright, Fast, and Interchangeable
HiViz’s LiteWave system uses exposed “wave” windows to let in more ambient light, giving the brightest possible fiber optic glow without batteries. MidwayUSA+1
The LiteWave design features a diagonal-wave exoskeleton, which protects the fiber while exposing maximum surface area to light—so the pipes glow strongly in daylight, low light, and indoor ranges. MidwayUSA+1
All-Steel Construction for Duty-Grade Durability
Unlike plastic or cast sights, the MPSLW11 uses all-metal construction with a rugged steel frame: Black Market Arms+2Palmetto State Armory+2
All-steel sight body for impact resistance and long-term durability
Black frame / green rear fibers, giving you a crisp sight outline with bright dots that jump into view Palmetto State Armory+1
Designed as a factory-height rear with a 0.140" wide notch for a balanced mix of speed and precision hivizsights.com+1
This makes the LiteWave rear sight tough enough for EDC, concealed carry, and duty use, where your pistol may see bumps, holster wear, and hard use.
Factory-Height Rear – Clean, Familiar Sight Picture
HiViz designed this sight to work as a factory-height rear, so your sight picture remains intuitive: hivizsights.com+2Palmetto State Armory+2
0.140" rear notch pairs well with common front sight widths for a clear light bar on each side of the front blade.
Intended to be used with the HiViz LiteWave fiber-optic front sight for S&W M&P & Shield (SW2014) for a matched, high-contrast set. hivizsights.com
You get the same basic sight picture style you’re used to, but with a dramatically brighter, more defined rear reference.
Easy LitePipe Changes with Included Key
The MPSLW11 comes with everything you need to customize the fiber color:
This flexibility lets you fine-tune your sight picture for carry, competition, or training.
Simple Upgrade for Faster, More Confident Shooting
Swapping to a HiViz LiteWave rear sight is one of the most cost-effective accuracy upgrades you can make on a Shield:
Brighter, more visible rear dots = faster sight alignment and easier focus on the front sight. MidwayUSA+2OpticsPlanet+2
Ideal for shooters with aging eyes or anyone who struggles with low-contrast black-on-black sights.
Great for concealed carry, home defense, and range use, where quick, confident sight pictures are crucial.
For best results, have a qualified gunsmith install the sight to ensure proper fit in your Shield’s dovetail. MidwayUSA+1
Limited Lifetime Warranty
HiViz backs the LiteWave rear sight with a limited lifetime warranty against manufacturing defects (LitePipes are considered wear items). hivizsights.com+1
That warranty—combined with rugged all-steel construction—makes the MPSLW11 a long-term upgrade, not just a cosmetic change.
