No...you are most certainly correct. And I would love to have one for my 39...but, I can't imagine using one for any practical purpose.Hello Dr., dont attempt to apply logic in this particular situation.
There existed a marketing and engineering dept trying to make the mod-39
as appealing as they could to our armed forces. This program at S&W
started after WW2. They had a lot of time and more importantly money
invested in the 9MM DA. I see your point, but dont think about it to much.
