The DXT2 Big Dot takes a different approach to defensive pistol sights. Instead of three matching dots that can blur together when your heart rate spikes, it uses one big, high-contrast front dot paired with a shallow V-notch rear. Line the dot up over the vertical bar and you get the "dot-the-i" sight picture, which is about as simple and fast as sight alignment gets. That large front dot measures 0.188 inches across, which is a big reason these are a go-to for folks fighting aging eyes or anyone who just wants to see the front sight without hunting for it.
The front dot uses an Optic Orange Glow Dot that soaks up ambient light and glows on its own as things get dim, bridging the gap before it's dark enough for the tritium to take over. Orange is the color to grab if you spend a lot of time in bright daylight, since it gives you strong contrast against most backgrounds. The convex shape isn't just for looks either. That curved surface pulls in more light, so the dot charges up brighter than a flat face would.
These are machined from steel bar stock, then blued to hold up against rust with normal cleaning and oiling. The steel handles drops, one-hand racking off a belt or barricade, and the general beating a carry gun takes. The rounded front sight has no sharp edges to snag on a shirt during the draw, and even at Big Dot size it clears most standard holsters. The convex dot is also gunpowder residue resistant, so a quick wipe with a cloth keeps it clean.
This set is cut specifically for the S&W M&P M2.0 Optics Ready pistols in full size and compact, covering common chamberings like 9mm, .40, and .45. It's a standard height sight, so it will not co-witness with a red dot. Install is a DIY job with a hammer and punch, and some setups may need a little filing to seat the sight into the dovetail. XS backs the DXT2 with a 10 year warranty.
This exact set is cut for the S&W M&P M2.0 Optics Ready pistols in full size and compact. If you have a non-optic-ready M&P, XS makes a different DXT2 and R3D fitment for those, so check your dovetail cut before ordering. Matching the sight to your specific slide is the difference between a clean install and a headache.
It comes down to your eyes and where you shoot most. Orange gives you the best contrast in bright daylight against varied backgrounds, while yellow tends to glow brighter in low light. Vision varies from person to person, so some folks simply pick up one color faster than the other.
Yes, this is a DIY-friendly job using a hammer and punch, and XS includes instructions. Some installs may need a bit of light filing to seat the sight into the dovetail. Skip the sight press or pusher tool on these and stick with the punch method.
No. This is a standard height sight, so it will not line up with a mounted optic for co-witnessing. If you run a red dot and want lower-third or absolute co-witness, you'd want a suppressor height set instead.
