Fitment Finder
Will it fit? Pick a pistol to see every optic it takes, pick an optic to see which guns it fits, or check rifle co-witness mounts. We partition results into direct fit, fits with a plate, and no known adapter — every row sourced and date-verified, never guessed.
Every gun we have fitment data for
28 pistols, each with its own page listing the optics that fit the factory cut, the ones that need a named adapter plate, and the ones with no known adapter.
