Get one while you can. Especially an older one.
My 629-2, the one shown, is a 4 inch standard. I load 240 gr simi-jacketed HPs at around 950 fps from that 4 inch for most uses. Plenty for hog. I only use top loads if I go in bear country and there ain't no bear country in Texas (well there are black bears but that just isn't the same as the Grizzly by far.)
Just throw on the El Paso 1942 holster, six or so spare rounds, and a field knife and you are good to go in the woods.
Nothing like a good N frame.
