I carry a 442 Airweight (J frame) in a pocket holster every day. I feel very confident in my ability to make center of mass hits at likely scenario distances with it. It's loaded with Speer's +P HP short-barrel load (135 grain I think). I like its small size and light weight- hence, I carry it every day, everywhere it's legal to, rather than leaving it at home like my Glocks, Kimber 1911, Springfield XD, etc. I don't shoot tons of duty ammo with it at the range because my hand starts to feel it, but in a real world shooting I doubt I would notice 5 shots at all. I would choose the model 60 if the K-frame 15 is noticeably heavier or bulkier (pocket bulge). If I wanted longer sight radius or "better" sights, I'd pack a full-sized semi-auto in a belt holster.
