If I had to carry a revolver this is what I would do personally.
While I have 2.5" and 4" Model 19s, I don't consider either ideal, though the 4" is a bit better.
The reason being anything less than a 3" barrel and you risk not getting complete ejection of empty cases during a reload.
While the 4" can work, I would opt for a 3" barrel and high visibility, adjustable sights.
That eliminates the Model 10s and 13s.
Ruger makes a perfect candidate in the 3" GP-100 .357 Mag. They can be found in both the standard and Wiley-Clapp version with a Novak rear and a fiber optic front. It is about as perfect as you could ask for.
Loaded with some Plus P .38s, with a speedloader in your pocket, or better yet, a J Frame. One should be pretty well set.
3" K Frame with adjustable sights or a 3" GP-100. Either would do nicely.

The Tikka T3 in .308 Winchester is the Glock 19 of the rifle world.
