Verify this onePublished fitment information for this slide is thin or
contested, so it carries a verify flag. SIG-LOC PRO slide assemblies for the P320 full-size and carry/compact. SIG's own spec sheet calls this footprint SIG-LOC PRO rather than SIG-LOC, and the two are treated here as separate patterns because nothing SIG publishes says they interchange. Top-mount optics still fit via the removable recoil-lug pins; the pattern is not published. Confirm with the plate maker before ordering.
On this modelSold by SIG as a SIG-LOC PRO slide assembly. Not the same footprint as the P365 SIG-LOC slide, and not the Romeo1Pro cut on a standard optic-ready P320 either — three different P320-family interfaces now exist.
The interactive
fit checker opens with this pistol already selected and gives
you a single verdict for any optic, plus a build sheet with the plate SKU, screw threads, torque figures
and install order. Every "how it mounts" cell above is a link to that pairing's verdict, and the address
bar there is a link you can send to someone.

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