Here's one the FBI issued to agents in the 1980s to carry. 13-1 shipped to Quantico FBI FTU Dec, 1980. Agents carried this duty revolver for over 10 years until the change over to the 1076. The bureau went from a manageable carry weapon in the K frame Model 13 .357 Mag to, for many, an unmanageable one for concealed carry purposes in the 1076. This is my carry weapon of choice today when I want a break from the M&P 40 Shield.
