This has posted several times, I wish Crimson Trace would make for more model S&W's, however, I have given up hope that they would spend the R&D money to make them for these now out-of-production guns. Especially models that don't have a lot of interchangability. If they are going to make another model for 3rd Gen S&W's--my money is on the full-size 45's and 10mm.
