Hello, I live in the Dallas-Ft. Worth Metroplex and have had Lou Williamson and son, Scott, work on several HPs over the past several years. Lou's first work on my first HP was in '71 when my HP's factory adjustable sights were replaced with S&W K-frame revolver sights and a serrated ramp was silver soldered to the slide. The gun was hard chromed (armalloyed). Over the years, I've had BarSto bbls fitted as well as BoMar sights on one HP. Hammers have been bobbed, and trigger jobs done. The latest job for me done at Williamson Precision Gunsmithing in Hurst, TX was to have a set of Novak fixed sights put on a MkIII HP. I like few changes, but do like good sights and a good trigger. On one HP that had particularly long overtravel, a trigger-stop was added. I routinely remove magazine safeties to improve trigger pull and add Spegel stocks. Best.
