Pistol red dot sights mount to the slide of a handgun and give the shooter a single aiming point to focus on, instead of lining up front and rear iron sights. The category covers open and enclosed red dot sights sized for full-size, subcompact, and slim handguns, with red and green dot models. Law enforcement officers, military users, concealed carriers, and competitive shooters all rely on pistol red dots for duty, carry, and competition.

Options include open and enclosed red dot sights, compact carry optics, and competition optics from top brands like Holosun, Trijicon, Sig Sauer, and EOTech. Models differ in dot color, reticle options, size, and mounting footprint.

Choose the optic based on how the pistol will be used. For a duty or carry pistol, an enclosed sight seals the emitter inside the housing, which helps keep dust, lint, and debris out. For concealed carry on a subcompact or slim pistol, a small open or enclosed sight keeps the added height and width low. A competition pistol suits an open sight with a large window, which gives a wider sight picture. Check the mounting footprint before buying, since the sight has to match the slide cut on the pistol, such as a Glock MOS cut, an RMR pattern, or Holosun's K footprint. Some models offer multiple reticle options, such as a dot, a circle, or a circle with a dot, and some add features like solar backup power and forward-facing light sensors. An optic also changes how the pistol fits a holster, so confirm the holster is cut for it.

Add a holster cut for an optic and a weapon light for low-light use. See more optics for the rest of the setup.
