I have a 1969 Colt Agent with a bobbed hammer, factory grips and Tyler T Grip that I pocket carry in a Mika holster. My belt carry gun is a '65 Colt Cobra with stag grips and a Tyler T Grip. I carry one or both all the time. I shoot the D frame Colts better than I do the Smiths and they carry 6 rounds. They're also like me, old and old school.
I have the LCR, 642 and S&W bodyguard38, and I find any of them are perfect for pocket carry. After adding a slightly longer grip to it, the 642 is now my favorite to shoot.
Old thread, but Ill comment anyway. Raindog said stay around $400 so I recommend a S&W 638. I got mine for $359, and I like it better than my KLCR simply because it has SA option, and is still "hammerless"(snag free) My SP101 2" DAO is a nice snub, but its a brick compared to the Airweight 638. I also have a Taurus 905(9mm) and its a good option in the $400 range also. There are lots of good quality, newly manufactured snub nosed revolvers in the $400 range.
