Very nice handguns. I guess my favorite would be the High Standard. Dad had one we shot when I was in junior high school. Can't remember the model but it was a target model with barrel weights and target grips and was a fantastic shooter when it was in Dad's hands. He killed many squirrels with that one and his Colt Woodsman. That 4 3/4" Heritage looks neat. All are nice!
My 4.75" grips are similar to yours. I bought it about a month ago. At the time, at Cabela's, they had the same revolver which included the .22 mag. cylinder also. But since I already have one with my 6.5" I opted to only buy the .22lr. About 7 years ago, when I bought the 6.5" it only came with the .22lr cylinder, but there was a form that came with it which let you order the .22 mag. cylinder, which I did. So, I saw no need to have another one. At that time, Heritage was not owned by Taurus so I don't know that I could use that same .22 mag. cylinder with the 4.75" revolver even if I wanted to. I have never tried to see if it will fit. I really see no need to.
