The S&W 648 is a Smith & Wesson K-frame revolver. This series has existed in various guises for over 100 years. Thus, the inescapable gravity of the classic lines and harmonious proportions isn’t surprising. And with Smith & Wesson’s experience, fit and finish are spectacular.
The barrel top is anti-glare serrated along its length. The hammer spur is checkered. The gun also has a transfer bar safety. This is always a nice feature that nearly ensures if gun won’t discharge if dropped. Until the trigger is pulled, the hammer and firing pin remain separated. When the trigger is pulled, the transfer bar swings up between the hammer and firing pin permitting the hammer pin to hit the transfer bar, which hits the firing pin. Bang!
