This is a tough question for me.
When I carry a revolver it's usually a Smith & Wesson Model 15, .38 spl, 4" Heavy Barrel. I really like the overall feel and balance of this gun, and It's a real pleasure to shoot.
I also sometimes carry a 4" blue L-frame Smith in .357 mag, or a snub Model 37 Airweight.
Around the house, walking the dog or just for fun, I sometimes carry a Single Action revolver, either in .357 mag or .44 mag, depending.
My traveling gun is an older S&W 5904 9mm.
You had to ask.
