2.5" 357 magnum, S&W Model 19 with 158 gr LSWC, or 158 gr JSP handloads. It's cerakoted, because I bought it used, pitted, about 20 years ago. It's been on a lot of hunting, hiking, & fishing trips.
It's funny - twenty years ago I think this list would have been dominated by magnum revolvers, now there's an awful lot of semi-autos, especially 10mm Glocks. That's not a bad thing, just an evolution.
I carry a 357 revolver unless I am in grizzly country then it’s a 44 mag revolver. I like semi-autos but with a revolver I can just strap it on and forget about it unless I need it.
S&W 329PD with some Buffalo Bore 255gr Keith Loads. I also have a Glock 29 that I have thought about carrying instead just because I have a light on it, you know for seeing the that things going bump in the night.
