A few years back I started a Ruger collection. Didn't work for me so I sold most of them off. Lost a few $$$ in the process. I have four highly collectables left. A rare original "Star" KS-4, an original "Star" KS-9 still in the original box,a fairly rare 9 1/2" blued "Star", and a N.I.B.KNR-5 convertible from 1975. I will be keeping these. The 4" KS-4 shoots right up there with my 4" M617-0. Just harder to reload. Big Larry
