I carry mine IWB when fishing a river or some such. Have taken squirrels (year around season) with it. I've shot nutria with it. I've shot moccasins with it. I've taken it salt water and finished 2-4 ft black tip sharks with it. It's just handy and melts in a good IWB. It is VERY accurate. With Federal bulk pack Lightening it'll group from the bench into 2" at 25 yards. It'll shoot close to an inch with RWS Target. That makes it a viable small game pistol and I've done just that with mine.
Beyond that, why wouldn't I wanna take my kit gun along on a fishing trip????? My CCW is usually a stainless .38 ultralite snubby in my front pocket. The kit gun is a utility tool on such trips and occasionally I'll just wanna do some plinkin' with it. Good to have along a 550 box of Lightening for such occasions. Mine is nothing expensive, just a little Rossi 511 Sportsman with rather excellent sights and a Pachmayr Compac grip. I've also seen used various H&R revolvers for this sort of thing. About any little compact revolver or even semi auto will do, though I do prefer revolvers for such.
