I was told to keep the DPMS hammer because it worked with both the .223 and the 9mm
I'll have to pass the specifics of this point on to someone else who knows more......but I think the 5.56 hammer will work with the OLY style 9mm's, but not the Colt/RRA style.
I think I remember reading about this in the FAQ at the top of this forum.
