I carry a SW 360PD in 357 mag when I hike. I think it weights 12 ounces. Actually hurts to shoot 357 kinda, so a better carry than range gun for salty loads.
I also have the same 329 in 44 mag, but it is pretty big. I think it weighs about 27 ounces? Anyway it is not pleasant to shoot with full loads, but a lot better than the 357.
I do think the 360 is a good carry.
