I've been trying to convert the Accro sights on my newer Colt Python to target Elliason sights. The problem is, I can't seem to locate a patridge front sight to match the Elliason rear sight ! My python is a newer model, and the front sight is of the "one-pin" configuration. I've tried everyone from Colt's Custom Shop to many of Colt's distributors, and some of the gunsmiths that they contract their work out to; NO LUCK ! Any help in locating such a part would be appreciated....
