Fits s&w 69 by Tbrad, May 14, 2021
I purchased this under the recommendation from XS company that it would fit my model 69. Indeed it does. I had to clamp the new front site and re-drill it for the role pin but it was a pretty simple process. Great sights I have them on several guns

Milling is easy by Mr.Durden, Verified Owner, May 23, 2025
I didn't realize that this came un-milled. You do have to mark and drill your own holes in the front sight to put the roll pin through. The original rear sight also has to be broken to get it off and replace it. Brownell on youtube has a good video o...

Product Info for XS Sight Systems DXW2 Big Dot Sight Smith & Wesson

XS DXW2 Big Dot Night Sights offer the best front sight visibility in all lighting conditions. DXW2 Big Dot sights drive focus to the front sight using an industry leading large, high-contrast front and a low profile V-notch rear. DXW2 Big Dot front sights use a patent pending glow dot that absorbs light and glows in low light levels before it is dark enough to see the tritium. Optic Orange is designed to offer a high-contrast sight picture when shooting in bright light conditions and maintain its visibility in decreasing light levels. To ensure visibility in low light when uncharged, optic orange is primarily based on yellow with a hint of red. The increased surface area of the convex dot increases light absorption, intensifying the charge of the glow properties of the dot. The dot-the i sight picture, with a tritium dot in the front sight and a non-tritium, white stripe in the rear, prevents confusing the front and rear sight in high-stress situations. In most gunfights, the victim and attacker are both moving and the victims focus is drawn to the threat. The wide field of view increases visibility of the front sight and of the threat downrange. Outside Diameter Big Dot 0.188"; fits in common holsters. Installation might require filing to fit sight to dovetail, do not use a sight press/pusher tool. Fits S&W M&P Shield & M&P M2.0 Shield; 9mm, 40S&W, & 45ACP.image

*S&W 586,686,625,629,329 Revolvers: Installation requires a drill press to drill the retaining pin hole in sight body. Might require filing to fit sight to dovetail.
