Some think the MIM guns have better actions, but it's subjective......a MIM and IL 3" Model 10 and 64 would be OK with me, give me 5 minutes after I got it home and the lock would be gone anyway...... I won't hold my breath for a return of the K-Magnum revolvers.
I stopped wishing for cool stuff to "return" and just hope S&W keeps making the stuff it does now. I would hate to ever see the 10, 64, 67 and 4" 620 get dropped.
I got a 3" RB 13 just because it was a good deal on a smith - didn't know much about the 3" RB's, but now I know what all the fuss is about. I bought an extra hammer, dehorned it and it is the slickest carry gun I got.
