Diagram is schematic — top-down, optic
front at the top — and is not to scale.
InterfaceBottom-mount, like SIG-LOC, over a longer footprint
What to knowSIG's specification sheet names this footprint SIG-LOC PRO, distinct from SIG-LOC, and sells it on P320 slides while the plain SIG-LOC goes on P365 and M17/M18. SIG publishes no statement that the two interchange, so this entry assumes they do not. Flagged pending confirmation.
Use the fit checker to see whether a specific optic and
pistol go together, and what it costs to mount.

this is worth more than a spec sheet — and nothing here changes without a source, so bring one.
