I've carried a J frame Smith for over 30 years: at first, a M36 in .38 Special, and later a M60 .357 Magnum. Both have 3" bbl's, and I carry OWB, 100% of the time. I prefer the 3" bbl's for their greater inter-sight distance which allows better accuracy...add's a bit of weight to dampen recoil, and are every bit as easy to conceal as the shorter 1-7/8" Smith bbl's. I do dress around the gun, and avoid wife beaters and speedos as a rule...at 78, those days are behind me!!
Both guns have adj. sights, and no, I've never had them get hung up on clothing during the draw movement. I like the adj. rear sight which allows me to zero any ammunition I care to load. For better visibility with my fading eyesight, I dab the front sights with white typewriter correction fluid or nail polish; it makes it pop right out in dim light. Too, I've never found adj. sights "fragile" as derided by some. And neither have two family members who had long careers in the Border Patrol, dating back to when they carried M66's, (which they prefer to the current issue bottom feeders: Sig, Glock et. al.)
As to loads, for many years, I carried the old "Treasury"/"FBI" load, (a good LSWC HP, at 950 fps), and handloaded them when commercial rounds were unavailable. I always loaded .38 Special brass to +P velocities, finding that the shorter case allowed surer ejection (even with the full length ejector rod on the 3" bbl'd guns), noticeably better than in .357 brass. Much later, when Speer finally came out with the good Gold Dot bullet, loaded for expansion from short bbl's, I made the change. Nowadays, I carry the 135 GD JHP in its .38 +P Special commercial offering. Both guns shoot it well, eject it promptly, and it hits where I'm looking.
As to the guns themselves, the M36 (blued gun below), has a better DA and SA trigger than the newer M60, but both are more than adequate out to 15+ yds, DA with my arthritic hands and 78 yo eyes doing the steering. The triggers improve with age and practice, but any decent gunsmith can tune them without jeopardizing ignition...(read: overly light trigger return and mainsprings).
So if you're considering a move back to the days of yore...carrying a revolver for civilian self defense, I doubt you could find a better combination than a good 3" bbl'd Smith, either a J or K frame. They do demand a training regimen to get acquainted and develop proficiency, but the process is far from the daunting odyssey as described by some. Hell, LEO's & civilians did it for near on a century... and you may find that mastery of the old design has it own level of satisfaction that many of us have come to cherish.

My normal carry position with M60 in the leather.
M36 with Pachmyar's
.357 M60 Smith and its understudy, M63 .22 LR
Same M60, but with "Bateleur" grips by Altamont. It's a pretty good grip up to .38 Special +P level, but beyond that the only comfortable option for me has been Hogue's Monogrip as seen in the pic above.
