Hello, I am new to this forum and just recently became a S&W owner. I have wanted one for years, but never took the time to research the different models and always seemed to find something else that caught my eye at the time. This weekend, I was able to purchase a very nice condition K38 with 4" barrel. After doing some research and asking some questions, I was told it is a '5 screw' made in the late 40's early 50's. I picked up two boxes of 158 gr Lead 38's and had a blast shooting it yesterday. Why did I wait so long???
