I looking for a size comparison between the Rossi 972(6" 357) and the Rossi 461/462(2" 357). I am interested in buying the 972. I already own a 462. I am very happy with my 462, and am looking for a 6" 357 that is lighter in weight than my 6" GP100. The 972 lists as 10 oz lighter than the GP100. My question... Is the Rossi 972 the same frame size as the 462, but with a 6" barrel, and a different grip?
