I think I understand your question. TK does make moon clips that fit 45 Colt rimmed cases. I believe you are asking if the Ruger that accepts 45 a.c.p. moon clips will also accept the TK moon clips for 45 Colt.
https://www.tkcustom.com/products/ruger-45-020-ssSorry I don't know the answer but would like to know. I have never had any interest in the a.c.p. in a Redhawk but agree with you that a moon clip loaded with 45 Colt rounds would be a handy carry option.
Hopefully someone will know.
