Description
The XS DXT2 Standard Dot puts a defensive twist on the traditional three-dot setup. Instead of trying to line up three glowing points under stress, you get a single high-contrast green Glow Dot up front and a clean vertical tritium bar in the rear. Together they form the "dot-the-i" sight picture, which keeps you from mixing up the front and rear when your focus is locked on the threat. It's a fast, intuitive system built for concealed carry and everyday defensive use on the slim Glock frames.
What Makes the DXT2 Standard Dot Tick
The front sight uses a photoluminescent Glow Dot with a convex face. That rounded shape gives it more surface area to absorb ambient light, so it charges up and stays visible in that tricky window before it's dark enough for tritium to take over. Green is a strong pick here since it reads bright in low light and holds a strong glow intensity. Behind that green dot sits a tritium vial, and the rear carries its own tritium bar, so the sights stay lit in full darkness too.
Sizing and Accuracy of the Standard Dot
The front measures 0.140 inches wide, which is the same width as a factory Glock front sight. That's worth knowing if you've heard XS sights are only for close-range work. This narrower Standard Dot covers roughly five inches of a target at 25 yards, so it gives you a cleaner reference for more precise shots than the oversized Big Dot version while staying just as quick to pick up. Plenty of folks find the standard size the sweet spot for speed and accuracy across distances.
Built and Backed Right
Each sight is CNC machined from solid steel bar stock at the XS shop in Fort Worth, Texas, and the whole set is covered by their 10-year warranty. The low-profile design clears standard holsters and won't snag on the draw. XS includes the tools to tackle the install at home, though a hammer and punch or a sight pusher and a little patience go a long way. If you'd rather leave it to a gunsmith, that's a solid call too.

Frequently Asked Questions
Will the DXT2 Standard Dot fit all four Glock models listed?
Yes, this set is cut to fit the Glock 42, 43, 43X, and 48 slim slides. It's the standard height version, so it's meant for irons-only use rather than co-witnessing with a red dot. If you're running an optic and need to see over it, you'd want the suppressor height DXT2 instead.
How is the DXT2 Standard Dot different from the XS Big Dot?
The Standard Dot front measures 0.140 inches wide, the same as a factory Glock front sight, while the Big Dot is 0.188 inches. The smaller dot gives you a cleaner reference point for more precise shots at distance while still being quick to find up close. Many people find the standard size the better all-around balance of speed and accuracy.
Do these DXT2 sights glow in the dark on their own?
They do. The front and rear both use tritium vials that glow around the clock without needing any charging. On top of that, the green Glow Dot front is photoluminescent, so it absorbs ambient light and stays visible in that dim window before it's dark enough for the tritium to shine.
Can I install the DXT2 Standard Dot sights myself?
You can. XS includes a front sight tool, hex wrench, and thread locker in the box, and the sights can be driven in with a hammer and punch or a sight pusher. If you're not comfortable working on your slide, a gunsmith can knock the install out quickly.
