This is a genuine used Smith & Wesson OEM bolt, spring, and plunger assembly — the old-style set for K Frame Model 19 revolvers chambered in .357 Magnum. The bolt is the part responsible for locking the cylinder in alignment with the barrel at the moment of firing, making it critical to both accuracy and safe operation.
