Xs Sights 27/31-38 Orng Defense Exp Setxs Dxw2 Big Dot For Glock 17-

XS Sights 27/31-38 Orng Defense Exp Set with Big Dot front sight for Glock 17 and compatible models delivers the speed and confidence of tritium night sights built for defensive shooting. This sight set pairs a high-contrast orange front sight with a low-profile V-notch rear, engineered so you can acquire your target fast in dim light or darkness. The Big Dot front sight—measuring 0.188" across—dominates your field of view and simplifies the sight picture to a straightforward dot-the-"i" alignment, cutting the mental math when speed counts.

Built for working shooters, the front sight's glow dot absorbs ambient light and shines in low-light conditions, backed by tritium that requires no battery and never fades. The rear sight features a white stripe for daylight reference without adding sight-blocker tritium to clutter your target view. A ledge machined into the rear sight aids one-handed slide manipulation—a practical detail for duty or defensive carry—while the durable CNC machined steel construction handles hard use without compromise.

The low-profile V rear sight design keeps your front sight in focus where it matters, and the complete set fits standard holster options so you're not locked into proprietary gear. Whether you run this Glock at the range, in training, or for concealed carry, XS Sights' no-nonsense approach to night sight design gives you reliable, fast target acquisition when light is scarce.

Frequently Asked Questions

Will these XS Sights fit my Glock 17?

Yes. This XS Sights 27/31-38 set is designed for Glock 17 and compatible models. The sight set is engineered to work with your Glock's standard dovetail and fits holsters built for factory Glock sight configurations.

Do I need a gunsmith to install these night sights?

XS Sights provides the sight set; installation typically requires removing the factory sights and drifting the new sights into the dovetail. Many shooters handle this themselves with a brass punch and rubber mallet, though a gunsmith can install them if you prefer professional fitting.

How long do the tritium sights glow?

Tritium is self-illuminating and does not require batteries. The tritium in the front sight provides automatic glow in low light and darkness and does not fade or require charging.

What's the difference between the Big Dot and standard dot sights?

The Big Dot front sight (0.188" tall) is wider and more prominent than traditional thin-blade sights, making it faster to acquire in defensive shooting scenarios and easier to keep in focus. The dot-the-"i" sight picture simplifies aiming so you can get on target quickly.
