It's about as far from a traditional hogleg as you can get, but oddly enough this is my trail gun: S&W 340 PD. Heck, it's really the only gun I cary anywhere these days.
It's the weight. I'm just not willing to lug around any extra weight these days. The pictured ammo weighs more than the weapon. I wish it had an exposed hammer, but when I bought it I needed a gun that would draw fast out of the pocket, so hammerless was the way to go.
It's hardly a tack driver, but it's more accurate than most people would suspect. Full-house .357's do kick quite hard...about like catching a baseball barehanded, but the first five aren't too bad. Regular .38's are a pussycat.
I'd love to have the same J-frame ultralight scandium and titanium revolver with a four inch barrel, but they don't make such a thing. I've thought about buying the model 60 and fitting my titanium cylinder to it, but I don't know how well that would work or how much weight I'd save.
The shotshells harvest grouse quite effectively. Anything else I'd shoot would have to be within biting distance anyway, so I guess it's accurate enough for me.
