Hi all. New to the forum, but already have two S&W's, a Model 10-8 and a Shield and am considering buying a 617 as a self Christmas gift. My only dilemma is should I buy a 4" or 6" model. So my question to you all is, is the extra 2 inches of sight radius so much better to be worth the extra 6 oz or is it of minimal value and the 4" is just fine and probably a little handier? I realize this is a subjective evaluation, but I would value the opinion of those with first hand experince of it before I plunk down a hefty chunck of change and forever wonder if I made the right call. I apreciate your input.
