The 642-2 is a Centennial-configuration J-frame with an internal hammer and double-action-only trigger. It features a five-shot fluted cylinder and a 1.875 in stainless steel barrel marked ".38 S&W SPL +P," aligning with the model’s +P rating.
Construction pairs a matte silver aluminum alloy frame with a matte stainless steel cylinder and stainless barrel for durability with reduced weight. Fixed sights consist of a fixed front sight and a rear top-strap gutter. Black rubber boot-style grips with molded diamond checkering panels provide a compact, secure hold.
Key identifiers include the yoke stamping "642-2," the product code/mfg part number 163810, and the two-line "SPFLD, MA S&W U.S.A." address marking. The factory fired case notes 5-groove right-hand rifling, consistent with S&W production of this period.
Dimensions and weight support its micro-size profile: approximately 6.3 in overall length and about 15.0 oz unloaded. The revolver incorporates S&W’s internal key lock safety and maintains a DAO action with an internal hammer for a snag-resistant profile.
