I purchased a mod.649 in SS 2-1/8" bbl. to replace my mod 60 38 spec.
The two are worlds apart IMO. The mod.60 while accurate enough to qualify with at 50 yds, it never could have been considered a pocket CCW (the exposed hammer hung up on just about every article of clothing it encountered, and the SS front sight was a real bear to line up rapidly.
OTOH, the 649 has been snag free and while I don't find the long range accuracy to be on a par with the 60, it is good enough for normal handgun range use. Being 357 gives it the edge in stopping ability.
A couple short comments; The trigger as it came from the factory was not up to the quality of the old 60 ( a few minutes with some judicious polish work solved this) and the hole in the side with the arrow that looks for all the world like a scratch is a useless POS that I will never use.
By the way, I paid 400 and change, new, a little over a year ago and thought I got a a bargain.
