I've gotta say if weight was all you were concerned about, the S&W 317 would be an attractive option, but not the best shooter, seeing as a 1 7/8, or 3" barrel isn't ideal for a field gun. I'm a bit of a traditionalist at heart, and would love a Bearcat, for the purposes you describe, but on a more serious not, my Browning Buckmark Camper has been an excellent rimfire, digesting most all bulk pack ammo, the finish seals the deal for me, I don't believe I've had a pistol resist corrosion like the Buckmark with it's matte, parkerized finish. I think one of these would meet your criteria quite well. They're not a pain to take apart, (I'm not sure they even prescribe a field strip in the manual, but it's not hard at all to take apart anyhow), reasonably accurate too, though I embarrassingly don't remember the last time I punched paper with mine. Mostly pop steel with it. The moniker is appropriate IMO, and the Browning Buckmark Camper, would make a great pistol for a Camper IMHO.
