I upgraded my S&W 22 to a S&W 586 and I am very happy. I shot my 586 for the first time last week. Many thanks to forum members for the advice on ear protection. My 586 came with Pachmayr grips that are very functional, but I do miss the wood grips on my S&W 22. As a novice to firearms, would I be in over my head in an attempt to replace the Pachmayr with wood grips? I haven't done a whole lot of research but it appears that there are not round butt 586's, all are square butt. Is this true? Thanks.
