My carry Airweight is usually a 1962 (or so) Mod 37 with a great action job. Other than that, it it stock. I bought it nearly new from a friend. When I'm not carrying that one in cargo shorts in the summer, I'm carrying a 1955 Agent with a factory hammer shroud. The Mod 37 is showing some slight wear, but the Agent is well used. It has a lot of character. I carry both in Kramer horsehide pocket holsters. They are my favorite.
