flop-shank you'r probably righ, that's an good opineon. Buy the way I have phoned my local gunstore and the have only 38 special fmj rounds, not realy sutable for defense, so I have to stick with the 357 mag rounds . 38 special special is no at very popular claliber here in austria, most of the revolver shooters are using either 357 mag or 44 mag. So I will stick the the R357M1.
