The 8 Best Red Dot Sights for Walther WMP are designed with an optics-ready slide, making it particularly appealing to shooters who want the faster target acquisition and aiming convenience of a red dot. Walther describes the WMP as a lightweight, low-recoil pistol with an optics-ready slide and multiple adapter plates, giving users flexibility when selecting an optic.
Choosing the 8 Best Red Dot Sights for Walther WMP, however, involves more than simply finding an optic that looks good on the pistol. Footprint, mounting plate compatibility, optic size, reticle design, battery life, durability, and sight height can all influence the final setup. The WMP’s factory documentation specifically lists an RMR adapter, while some of the optics in this list use different mounting patterns.
8 Best Red Dot Sights for Walther WMP
1. Trijicon RMR Type 2 3.25 MOA Adjustable LED Red Dot Sight
The Trijicon RMR Type 2 is one of the most established pistol red dots in this group. Its 3.25 MOA dot provides a useful balance between precision and rapid target acquisition, making it suitable for shooters who want a straightforward aiming point without a complicated reticle. The adjustable LED version also gives the shooter control over brightness settings, which can be helpful when moving between different lighting conditions. Trijicon offers the RMR Type 2 in several reticle configurations, including the 3.25 MOA adjustable LED model.
For the Walther WMP, the important consideration is mounting compatibility. Walther’s WMP manual lists a dedicated Trijicon RMR adapter, meaning the RMR Type 2 can be an appropriate optic when installed with the correct WMP adapter and hardware. This makes it considerably more relevant to the WMP than optics that use unrelated mounting patterns.
The RMR Type 2 is especially attractive if durability and a proven design are high priorities. Its relatively compact form keeps the pistol’s profile manageable, while the simple dot reticle makes the sight easy to use. For a WMP owner looking for a premium traditional pistol optic, this is one of the strongest options on the list.

The Holosun 407C is another strong choice for the Walther WMP because it uses the RMR footprint. The 407C is designed as a full-size pistol optic with a simple 2 MOA dot, giving it a clean sight picture that works well for shooters who prefer a single aiming point. The design also incorporates features such as Solar Failsafe and Shake Awake technology.
The 2 MOA dot is smaller than the 3.25 MOA dot on the Trijicon RMR Type 2, giving the 407C an emphasis on precise aiming. Its RMR-compatible mounting pattern also makes it a logical candidate for the WMP when used with the appropriate RMR adapter. Walther specifically identifies the 407C alongside RMR-pattern optics in its optic-plate system.
Another advantage is its power-management system. The 407C family offers motion activation and solar backup, while the X2 version uses a side-loading CR1632 battery and is rated for up to 50,000 hours at a specified brightness setting. These features make the optic convenient for regular use and reduce the need for frequent battery replacement.

4. Trijicon Sig P220/229 HD Night Sight Set
The Trijicon Sig P220/229 HD Night Sight Set is different from the other products on this list because it is not a red dot sight. It is a set of conventional night sights designed for specific SIG Sauer pistol models. Therefore, it should not technically be classified as one of the best red dots for a Walther WMP.
Nevertheless, if the purpose of your article is to compare the products you supplied, this product can be mentioned as an alternative sighting system rather than a red-dot optic. Traditional iron sights can provide a battery-free aiming system, but compatibility with the WMP must be confirmed before considering any particular replacement sight set.
For a WMP-focused article, this product is better treated as a backup/alternative sight category, not as a direct competitor to optics such as the RMR Type 2, 407C, or RFX11. If the goal is a strictly accurate “Best Red Dot Sights for Walther WMP” article, I would recommend replacing this product with an actual WMP-compatible red dot.

8. HOLOSUN 510C Multi-Reticle 2 MOA Dot & 65 MOA Circle
The Holosun HS510C is a highly versatile open-reflex optic featuring a 2 MOA dot, 65 MOA circle, or combination circle-dot reticle. It also provides Solar Failsafe and Shake Awake technology, making it one of the more feature-rich optics in this group.
However, its application on the Walther WMP is less straightforward. The HS510C is designed around an integrated quick-detach Picatinny mount, rather than the compact slide-mounted footprint used by pistol optics such as the RMR Type 2 and HS407C X2. Holosun lists its direct mount as a Picatinny rail.
The large viewing window can make target acquisition quick, but the optic’s approximately 4.94-ounce weight and 3.3-inch body are substantial for a pistol slide. Consequently, while it is an excellent open-reflex optic for appropriate platforms, it is not one of the strongest practical choices for a conventional WMP slide-mounted setup.
Features
- 2 MOA dot
- 65 MOA circle
- Solar Failsafe
- Shake Awake
- Titanium protective hood
- Picatinny QD mount
Pros
- Large viewing window

Cons
- Large for a pistol
Factors to Consider When Choosing the 8 Best Red Dot Sights for Walther WMP
Reticle Size
Reticle size affects how quickly you can pick up the aiming point and how precisely you can use it. A 2 MOA or 3 MOA dot provides a relatively clean aiming point, while larger circle-dot combinations can make the reticle easier to locate quickly.
For the WMP, a simple 2–3 MOA dot is a good starting point for shooters who prefer an uncluttered sight picture. Multi-reticle designs such as those on the OSIGHT X and MPO-S provide more flexibility if you like switching between precision and faster-acquisition patterns.
Weight
Because the optic sits on the reciprocating slide, size and weight matter. A large optic can make the pistol feel less balanced and may be less practical than a compact pistol-specific model.
The Viridian RFX11 is particularly lightweight, while the HS510C is considerably larger and heavier. For most WMP users, a compact optic designed specifically for pistol applications is likely to make more sense.
Battery Life
Battery life is another important consideration, particularly if the pistol is used frequently. Long battery life reduces maintenance and makes the optic more convenient.
The Holosun HS407C X2, for example, is rated for up to 50,000 hours at setting 6 and incorporates Solar Failsafe and Shake Awake. The Viridian RFX11 is listed at approximately 30,000 hours at its middle setting.
Durability
The WMP is well suited to outdoor recreational use, so an optic with a durable housing and weather resistance can be beneficial. Look for rugged construction, water resistance, and a lens that can withstand normal handling and environmental exposure.
