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.

On this modelSubcompact sibling of the RM1C. Rost Martin publishes a plate set for the RM1C but doesn't say whether the RM1S shares that cut, so this entry doesn't assume it.
