This may be a long shot, but I am interested in trading my 4 inch Model 19 for a K 38 with 6 inch barrel. I am 76 years old and the 4 inch does not give enough sight radius for my plinking and informal target shooting. My S&W has custom Hogue wooden grips and a custom leather holster. I am not interested in an outright sale, but would love to have a 6 inch revolver.
