TAURUS 651 .357 MAG.
Interesting compare reliability of mechanizm, whom will comment?
And what was the prototype for both ?
Same. Taurus actually copied Smith quite a bit. Taurus is considerably cheaper, but only slightly lower in quality. A family member has one, and it's served reliably for twenty years or so now.
Let me tell you, .357 in a tiny revolver like that (especially the lightweight ones!) hurts like a mofo! And my hands are much tougher than average.
