I have my Dad's 1959 or 60 SS just like yours but the 3 screw. Probably never wear it out. My brother and I grew up shooting it. My down size is I shot a lot and easier to load semi autos worked better for me. Then I started buying 22 Masterpieces.

I still use the Ruger and have taught many folks how to shoot pistols using it. I also sent it back for the upgrade. It is safer gun.

I think you will like it. The 4 5/8th bbl is great for carrying.
