had an ffl 40n yrs. ago and bought/sold on limited basis. had hands on many "cool" handguns. would love to have a 4" and 6" colt python and a 22 diamond back (4" 22lr). oh well--times change.
I can't think of a single handgun (guess I just like the modern ones)....however I would have LOVED to be pick up a Thompson 1928 before the NFA stuff came about.
