Are standard Ruger MK IV and MK IV 22/45 magazines compatible?

Are the mags which fit the standard Ruger MKIV and the 22/45 MKIV pistols compatible with each other?

I'm not sure about the Mk IV regular and 22/45 but the MkIII MAG BODIES are the same. The basepads ARE different. I have borrowed my regular mkIII mags to use in my mkIII 22/45 by putting aftermarket base pads.
