Wonder if hed sell the grip off of it?

It wouldn't fit the modern Handi's, look at the extra metal (tang) on the receiver. You could probably make something similar, yourself for your Handi, if you have the wood working skills.
I think if you wanted something like that you'd be better off just getting a Contender. Pick your caliber 'cause there are a number of options for those

. Or, now that I think of it, didn't Rossi come out with Wizard pistols?
