My first EDC was a Mod. 37 in a custom paddle holster. It was replaced by a first generation Glock Mod. 19 in a Galco holster.
After a few years I decided to carry what I really liked and shot very well, a Colt Officers Model. It goes with me every day, in the brief case, a Galco inside the waist band holster or a Don Hume paddle holster with extra magazines.
The Glock was sold but, I still have and occasionally carry the Mod. 37.
