The XS Sights DXT2 Big Dot is a front and rear sight set built specifically for the Sig SP2022, and it takes a different approach than your standard three-dot setup. The idea is speed. A big, bright yellow front dot pulls your eye straight to it, while the shallow V-notch rear stays out of the way so you get a wide, unobstructed view of the front sight and whatever's downrange. Line the dot up in the V and you've got your sight picture. It's about as intuitive as aiming gets.
The front sight runs a 0.188 inch dot, which is wide by design and easy to pick up in a hurry. It combines a tritium vial with a photoluminescent glow dot, so the front absorbs ambient light and keeps glowing in that in-between low light before it's dark enough for the tritium to take over. The rear carries a tritium bar to complete the dot-the-i picture in full dark. Yellow is the color to grab if low-light glow is your priority, since it soaks up the most light and puts out the brightest charge of the two front options.
The sight bodies are CNC machined from steel bar stock and finished in a matte blued surface, so they hold up to drops, racking off a barricade, and years of regular carry. The convex dot shrugs off powder residue and wipes clean with a cloth, and XS rounded the front post so it won't snag on clothing during the draw. It's a large front sight, but it still clears most holsters made for the SP2022.
These are designed to install with a hammer and punch, though a lot of folks hand the job to a gunsmith for peace of mind. The set ships with a hex wrench, front sight tool, and red threadlocker to get you started. XS backs the tritium with a 12-year glow warranty to the original owner, which is what you'd want out of a defensive night sight.
Yes, this set (part number SI-0022S-5Y) is cut specifically for the Sig SP2022 slide. It includes both the front and rear sight so you're getting a matched set for that pistol. If you own a different Sig model, XS makes the DXT2 for other platforms under different part numbers, so double-check the fit before ordering.
It comes down to how you use the gun and how your eyes work. Yellow absorbs the most ambient light and puts out the brightest low-light glow, so it's the pick if night visibility matters most. Orange tends to contrast better against varied backgrounds in daylight, so it's worth considering if most of your shooting happens in bright conditions.
These are designed to install with a hammer and punch, and the kit comes with a hex wrench, front sight tool, and red threadlocker to help. That said, plenty of people prefer to have a gunsmith handle it for a clean, correct fit. Keep in mind that sights installed improperly aren't covered under warranty, so if you're not confident, professional installation is a safe bet.
XS warranties the tritium glow for 12 years to the original purchaser. The tritium naturally dims over its lifespan, which is normal for any tritium sight. On the yellow DXT2, the photoluminescent glow dot also charges off ambient light, giving you an extra layer of visibility in that low-light window before full dark.
