I haven't owned a .357 is a while and now have the itch, so am looking for a recommendation. What I would really like appears to be "unobtainium": a 2.5 to 3.5 inch, medium frame sa/da, round butt 6 shot. In other words, the FBI issue Model 13 from the 1980s. Absent finding a rare used model 13, I would like to get as close to that as I can. Any suggestions?
