I believe you have one of the ultimate of the rare and desirable S&Ws. I believe that there are a handful of guns that S&W got just right, then only made a few. Here they are, according to me (having no real credentials or authority to state an opinion), and in no particular order:
1. YOUR 44 Magnum!
2. 3.5" Registered Magnum
3. Target Triple Lock 44 Special
4. 3" Model 19-2
