Donno nuthin about Howa, but the Rossi short rifles that I have handled, with the octogon barrels and case hardened frame have been really nice! I think you will be happier in the long run with the case hardened receivers. Some CAS venues do not permit the brass frames anyway, such as NCOWS, because the 92 was not originally made with a brass frame...'S a matter of personal taste though and I'm sure you will be happy with whatever you decide on there.
