XS Sight Systems DXW2 Big Dot Sight Walther Review

Let’s Talk About XS Sight Systems DXW2 Big Dot Sight Walther

The XS Sight Systems DXW2 Big Dot Sight Walther is a high-visibility sighting system designed specifically for the Walther PPK, PPKS, and TPH pistols chambered in .380 ACP. Manufactured by XS Sight Systems, this sight aims to provide rapid target acquisition in all lighting conditions, from bright daylight to low-light environments. I was initially drawn to the XS Sight Systems DXW2 Big Dot Sight Walther because I was seeking an improved sight system for my Walther PPK/S, a pistol I often carry due to its compact size. The factory sights were, to put it mildly, inadequate for quick and accurate shooting, especially in less-than-ideal lighting.

Upon unboxing, the sight components appeared robust and well-machined. The large front sight immediately catches the eye, a testament to the “Big Dot” design philosophy. The optic yellow ring surrounding the tritium vial seemed exceptionally bright, even in ambient light. The rear sight, a simple V-notch with a white vertical stripe, complements the front sight nicely without being distracting. Compared to other night sights I’ve used, like Trijicon HD or Meprolight Tru-Dot, the XS Sight Systems prioritizes speed of acquisition over pinpoint precision. I ultimately chose the XS Sight Systems DXW2 Big Dot Sight Walther over others due to its reputation for being incredibly fast to acquire and its suitability for close-quarters defensive scenarios, which is precisely the role my PPK/S fills.

My first impression was a mixture of excitement and slight apprehension. While the large front sight promised unparalleled visibility, I was also concerned that it might be too large, potentially obscuring the target at longer distances. The need for gunsmithing to install the sight added another layer of hesitation.

Real-World Testing: Putting XS Sight Systems DXW2 Big Dot Sight Walther to the Test

First Use Experience

My initial testing of the XS Sight Systems DXW2 Big Dot Sight Walther took place at an indoor shooting range. I focused on close-range drills, simulating self-defense scenarios from 3 to 15 yards.

The difference in target acquisition speed was immediately apparent. The large, bright front sight practically jumped into my field of view, allowing for significantly faster sight alignment compared to the factory sights. Even under the artificial lighting of the range, the optic yellow ring was highly visible, and the “dot-the-i” sight picture proved intuitive.

Extended Use & Reliability

After several months of regular use, the XS Sight Systems DXW2 Big Dot Sight Walther has proven to be remarkably durable. There are no signs of wear and tear on the steel construction despite frequent handling and dry-firing. The tritium vial continues to glow brightly in low-light conditions, and the optic yellow ring maintains its luminosity after being exposed to light.

Cleaning is straightforward, requiring only a quick wipe with a cloth. I have found that occasionally using a small brush to remove any accumulated debris from the rear sight notch helps maintain optimal visibility. Compared to my previous experience with traditional three-dot sights, the XS Sight Systems DXW2 Big Dot Sight Walther offers a substantial improvement in speed and ease of use, especially in dynamic shooting situations. It may not be ideal for bullseye shooting at 25 yards, but for its intended purpose as a defensive sight, it excels.

Performance & Functionality

The XS Sight Systems DXW2 Big Dot Sight Walther performs exceptionally well in its intended role: providing a fast and highly visible sighting system for close-quarters defensive shooting. The large front sight is easy to acquire quickly, even under stress.

The “dot-the-i” sight picture is intuitive and helps to prevent confusing the front and rear sights. The primary weakness is long-range precision; the large front sight covers a significant portion of the target at distances beyond 15 yards. It meets and exceeds expectations for close-range defensive use.

Design & Ergonomics

The steel construction of the XS Sight Systems DXW2 Big Dot Sight Walther feels solid and durable. The snag-free design ensures it won’t catch on clothing during concealed carry. The large front sight is exceptionally visible, but some may find it aesthetically unappealing. There is a slight learning curve associated with transitioning from traditional sights, but the intuitive nature of the “dot-the-i” sight picture makes it relatively easy to master.

Durability & Maintenance

The steel construction and blued finish of the XS Sight Systems DXW2 Big Dot Sight Walther suggest it will last for many years with proper care. Maintenance is simple, primarily involving occasional cleaning with a soft cloth and a brush.

Replacing the tritium vial may be necessary after 10-12 years, but this is a standard maintenance issue for all tritium-illuminated sights.

Accessories and Customization Options

The XS Sight Systems DXW2 Big Dot Sight Walther is primarily a standalone sighting system. While there are no direct customization options for the sight itself, the improved sight picture can be combined with other modifications to the Walther PPK/S, such as upgraded triggers or grips.

It is compatible with most standard holsters designed for the Walther PPK/S, though it is recommended to check for proper fitment after installation due to the larger front sight.
