A reference for mounting optics to pistol slides: 168 slides,
71 optics, 17 footprints and 35 mount systems.
Every answer tells you whether it bolts straight on or needs an adapter plate, which plate, what thread the
screws are, what to torque them to, and whether your iron sights will still co-witness.

Start hereThe fit checker answers a specific pairing and
produces a build sheet you can take to a bench: parts, which bag each screw comes from, torque figures and
the install order. Or browse by pistol, by optic, or by
footprint.
What makes this different
It tells you the screws and the torque. Most compatibility charts stop at "needs a
plate". The thread lives in the slide or the plate, not the optic, which is why you end up with three bags
of screws and no idea which pair is right — so every answer here names the joint, the thread and where the
screws come from.
It admits what it doesn't know. 3 mount systems carry a verify flag because
published fitment data for them is thin or contested. A confident wrong answer costs you more than an honest
"check with the plate maker".
It won't guess a screw length. That depends on your exact stack, and a screw that is
too long reaches the striker channel. You get the thread, a calculator that works on your own caliper
measurements, and a straight warning.
