XS Sights Big Dot night sights are a strong match for Glock owners who want a large, easy-to-find front sight with low-light visibility. The DXT2 yellow version is best for buyers who prefer a yellow front dot, while the orange version offers a different color contrast. The DXW2 combines a static front with a tritium rear. One enclosed red-dot optic is included as an alternative for buyers comparing sighting systems, not as a Big Dot iron sight.
| Product | Best suited for | Main distinction |

| DXT2 Yellow Front | Glock owners seeking a yellow tritium front | Tritium front and rear |
| DXT2 Orange Front | Buyers preferring an orange front dot | Tritium front and rear |
| DXW2 Big Dot | Buyers wanting a static front and tritium rear | White-striped rear, Glow Dot technology |
| DXT2 Large-Frame Fit | Owners of listed larger Glock models | Fit listing includes Glock 20, 21, 29, and others |
| Osight SE Enclosed Optic | Buyers considering a red-dot alternative | Enclosed optic with selectable reticles |
XS Sights DXT2 Yellow Front
Best for: Glock owners who want a yellow front sight paired with illuminated tritium sights at both ends. The product listing names a broad range of Glock models, including several compact, full-size, and MOS versions. Check the exact model and generation against the listing before ordering.
The DXT2 uses a large front dot intended to make sight acquisition easier, and its tritium illumination works without batteries. The front is yellow, and the rear also contains tritium. Choose this version if that color is your preferred visual contrast; it was selected for combining the Big Dot design with front-and-rear low-light illumination.
Limitation: The listed fit is broad but not universal across all handguns. Confirm the precise fit for your Glock before purchase.
XS Sights DXT2 Orange Front
Best for: Glock owners who prefer an orange front dot. Like the yellow version, this set has tritium in both front and rear sights, providing battery-free illumination in low light. Its large front sight is designed to help users locate the aiming point quickly.
The listing identifies several Glock models, including the 17, 19, 19X, 22, 23, 24, 26, 27, 34, 35, 45, and 49. It is a useful color alternative to the yellow DXT2 rather than a different sighting layout. Choose it if orange stands out more clearly for your eyes and lighting conditions.
Limitation: The listed model fit does not establish compatibility with every Glock variant. Verify your specific pistol and generation.
XS Sights DXW2 Static Front
Best for: Buyers who want a Big Dot front with a static front element and a tritium rear. The DXW2 uses a white-striped rear without tritium, while its Glow Dot technology absorbs ambient light and emits a soft glow in low-light conditions. The dot-the-i sight picture is designed to make vertical alignment intuitive.
This model is a better choice than the DXT2 for shoppers specifically seeking a non-tritium, white-striped rear arrangement. The product description identifies it for Glock pistols and tactical applications, but does not provide a detailed model-by-model fit list in the supplied information.
Limitation: The front is not described as tritium-illuminated, so buyers seeking tritium at both ends should compare it with the DXT2 sets.
XS Sights DXT2 Large-Frame Fit
Best for: Owners of the Glock models specifically named in this listing, including the 20, 21, 29, 30, 36, 37, 38, 39, 40, and 41. This DXT2 set has tritium in the front and rear and a large front dot designed for quick sight acquisition.
Choose this listing when your pistol is one of the stated models; its fit details differ from the other DXT2 listing, which focuses on a different group of Glock models. The self-illuminating tritium does not require batteries, making this option relevant for buyers who want a conventional iron-sight set with low-light visibility.
Limitation: The supplied features do not specify the front-dot color for this listing. Check the product details to confirm the configuration before ordering.
Osight SE Enclosed Red-Dot Optic
Best for: Buyers comparing a red-dot optic with Big Dot iron sights. This is not a Big Dot night sight. It has an enclosed optic design, a side-loading battery, and a red multi-reticle system that can switch between dot-and-circle, dot-only, or circle-only patterns.
The enclosed construction is described as sealed against the elements, and the side-loading battery can be replaced without removing the optic. This makes it a distinct option for shoppers who prefer an electronic aiming solution rather than a large front iron-sight dot.
Limitation: The listing specifies an RMSc footprint, but the supplied information does not confirm fit for a particular pistol. Check the firearm and mounting requirements before choosing it.
Buying Guide: How To Choose Big Dot Night Sights
Which front-dot color should you choose?
Choose between yellow and orange based on which color is easier for you to distinguish against your usual backgrounds and lighting. The two DXT2 options have the same general front-and-rear tritium arrangement in the supplied features; the stated difference is the front color. Individual visibility can vary, so color preference is personal rather than a guarantee of improved accuracy.
Do you want tritium in both sights?
DXT2 listings specify tritium in the front and rear, with battery-free illumination. The DXW2 has a static front and tritium rear, plus a white-striped rear and Glow Dot technology. Compare these layouts according to whether illuminated tritium at both ends is important to you.
How should you check Glock compatibility?
Match the exact firearm model and generation to the product’s fit information. Some listings name specific Glock models or MOS versions, while the DXW2 information provided here is less specific. Do not assume that a sight fits every Glock because it fits several models.
Are iron sights or an enclosed optic a better fit?
Big Dot sights are iron sights with a prominent front reference. The Osight SE is an electronic optic with selectable reticles and a battery. Compare the sighting format, stated mounting footprint, and your firearm’s requirements. The products are not interchangeable simply because both help with aiming.
