BudsGunShop.com - 3 Dot Sights

Leland, this has Glocks standard white dot front sight and white U shaped line rear sight. Hope this helps.

Unless Bud's considers the Standard Glock sights "3 Dot" then it's just an error in the description.
Going by the Upc this is the basic Glock front white dot with rear white goal post sights.

Leland, this UPC code has Standard Glock Fixed Sights which is Front White Dot And Rea Goal Post White Sight. Pictured here : thetruthaboutguns.com/i-dont-like-my-glocks-sights-what-do-i-do/

Leland, fixed sights, Front: White Dot, Rear: White Outline. Have a great day!
