Here is a 686 & 66 to compare - no sweat I will post a pic of a 66 - 686 3in 357 next to a 3in 629 or 625 Wife & I been taking pics for auctions
The "Plus" guns in my opinion are a way S&W made up for its companies inadequacies plain & simple - nothing anyone would shoot with a 357 or 44 magnum would require 7 or 8 shots if you require that perhaps a M60 or m240 is what you should be carrying.
No MIM here
