You old timers probably have seen this before, but I am new to the site and this is my first post........ so I wanted to try and contribute something useful. Hopefully someone can use it. I recently bought a Taurus 191109BHW S and love it. Have enjoyed reading all you fellas stuff for a while. By the way, 1st letter of your Serial # is guage, 2nd is the year, and 3rd letter is the month.
