This "N" frame Smith and Wesson .357 Magnum is a favorite for its proportions. I like the 4" and even the 6" but I consider this 5" barrel the ultimate length for overall balance and aesthetics.
Being a 'dash 2" this is pinned and recessed, meaning the chamber mouths are counter-bored to accept case rims and the barrel is secured to the frame by a pin. The "N" frame is strong and will accept hot loads well, although I tend to prefer using reduced loads for quantity shooting. This gun pleases the eye every time I see it! This one is circa 1977 which was close to when the 5" ceased production.
