K-Frame .38s are great guns. I have a bunch of 'em. Model 10s, 12s, 15s, 64s, 67s, etc..
Top one was my Grandfather's. Can't go wrong with 64s. I have a gaggle of them. Bull barrels, tapered barrels, pinned barrels, snub noses, etc... they are classic guns of a bygone era. They are indestructible since they're K frame .38s and they are a joy to shoot. Simply keep them timed and don't do stupid stuff and they'll outlast you.
