New to red dots? What footprint, plate, co-witness and the rest mean
Verify this onePublished fitment data for this slide is thin or
conflicting. These slides take plates, but no maker or vendor publishes a fitment chart for them. The footprints below are the ones commonly offered for slides like this. Treat them as a question to ask the plate maker, not a confirmed fitment. Confirm with the plate maker before ordering.
Cheapest ways to mount it
Same slide cutMakers with the same cut: Walther WMP and Rost Martin RM1S. The optics that
fit are the same; the screw thread and the sights can differ, and each page says what is on file.
On this modelPlate vendors sell the standard Ruger American adapter with a 'will not fit Competition' warning, so the Competition slide is a different cut. No maker or vendor publishes a footprint chart for it.
