Start out with the K frame 38's and work your way up in caliber to the N frames. Or do what I did a bunch of years back. Always wanted a nice 44 special. Wasn't really looking for one at a local gun show. Found a 6.5" bbld 624 and it went home. Then a 3" 24-3 and then a 4" 24-3. All in the space of about a year and a half. it's like potato chips, you just can't have one. Frank
