The 1 7/8" stainless barrel carries a shrouded ejector rod that streamlines the profile and protects critical parts during carry. Fixed sights consist of an integral serrated ramp front and a square-notch trench rear, a proven combination for snag-free drawing.
Its internal hammer design eliminates external edges, making this Centennial-series revolver well suited for pocket or ankle holsters. The smooth, combat-style trigger delivers consistent double-action pulls without the interruption of a single-action notch.
Being a pre-lock, forged-part S&W from the early 1990s, the revolver retains the traditional build quality collectors seek. The plus-P rating expands ammunition choices while preserving the lightweight J-Frame dimensions.
An aftermarket black synthetic boot grip is installed for reduced printing and improved concealment. For collectors who prefer the classic look, the original walnut service grips are included and can be reinstalled without modification.
