I have two 28's, a four and a six inch. The six inch has S&W target stocks. The four inch has magna stocks. As soon as I can find a good pair, it will have the S&W target stocks. My 21-4 has the factory smooth round butt grips. I am not wild about them. I prefer the square butt configuration. My 625-2 has the standard Hogue finger groove grips. I like the way they feel, but to my eyes they leave very much to be desired in aesthetics. I have used the Pachmayer Presentation on a number of my N-frame pistols. Happily these grips work on either square or round butt revolvers. If and when I can manage it, I will almost certainly put round butt to square butt target stocks on both the 21-4 and the 625-2. If at a later date I need to carry the 21-4, I will replace the round-butt grips, but that will not likely be necessary.
