The XS Sights DXT2 Big Dot is built to solve the oldest problem in defensive shooting: finding your front sight fast when it counts. This set is cut specifically for Colt 1911 Enhanced slides with a BCMS rear dovetail, and it swaps out the small, hard-to-read factory sights for a large, high-contrast front dot in Optic Yellow. The front measures 0.188 inches wide, which is genuinely big, and it combines a tritium vial for true darkness with a photoluminescent glow dot that charges off ambient light and stays bright in that in-between dusk lighting before the tritium takes over.
Instead of the usual three-dot lineup, XS uses what they call a dot-the-i sight picture. You drop that big yellow front dot right on top of the tritium bar in the rear V, and the alignment happens almost instinctively. Testing has shown the yellow front glows the brightest and soaks up the most ambient light of the DXT2 color options, so it is a strong pick if low-light visibility is your top priority. The rear sight keeps a shallow, low-profile V that gives you a wide, unobstructed view of that front dot.
The sight bodies are CNC machined from solid steel bar stock at the XS shop in Fort Worth, Texas, so they hold up to drops, racking off a belt or barricade, and years of regular carry. The convex dot shrugs off powder residue and wipes clean, and the rounded profile has no sharp edges to snag on clothing during a draw. Even at Big Dot size, the front still fits most standard holsters.
This set is dovetail-specific to the Colt 1911 Enhanced with a BCMS cut, so double check your slide before ordering. The kit includes the front sight, rear sight, red threadlocker, and instructions, and XS designs these for install with a hammer and punch. If you are not comfortable pressing sights yourself, a gunsmith can knock it out quickly. XS backs the tritium with a 12-year warranty.
This particular set is cut for Colt 1911 Enhanced slides with a BCMS rear dovetail. The 1911 world has several different dovetail cuts, so check your slide against the BCMS spec before ordering. If your slide uses an LPA or Novak cut, XS offers a different DXT2 variant for those.
Both use the same tritium and glow dot setup. XS testing found the orange front tends to show up best in bright daylight, while the yellow glows the brightest in low light and absorbs the most ambient light. If maximum night visibility is your priority, yellow is the pick.
XS designs these to be installed with a hammer and punch, and the kit comes with threadlocker and instructions. That said, sight installation takes care and the right tools to avoid marring the slide or the sight. If you are not set up for it, a gunsmith can handle it in a few minutes.
Rather than lining up three dots, you place the big yellow front dot directly on top of the tritium bar in the rear V-notch. It reads like dotting the letter i, which most people find faster and more intuitive under stress. The shallow rear V keeps your view of that front dot wide open.
