It engages the cylinder ratchet and rotates the cylinder into alignment with the barrel as the hammer is cocked. Proper hand function is essential for reliable operation, accurate shooting, and safe cylinder lockup. A worn or damaged hand can cause timing issues, cylinder drag, or failure to rotate properly.\u003c\/p\u003e\u003ch3\u003eWhen to Replace the Hand Assembly:\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCylinder fails to rotate properly\u003c\/li\u003e\n\u003cli\u003eCylinder timing is off (misalignment with barrel)\u003c\/li\u003e\n\u003cli\u003eVisible wear on hand engagement surface\u003c\/li\u003e\n\u003cli\u003eCylinder drag or binding during rotation\u003c\/li\u003e\n\u003cli\u003eLight primer strikes due to timing issues\u003c\/li\u003e\n\u003cli\u003eAs part of complete timing and lockup rebuild\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy Choose Genuine OEM Parts?\u003c\/h3\u003e\u003cp\u003eFactory replacement hand assemblies are manufactured to the exact same specifications, tolerances, and materials as the original components installed at the Smith \u0026amp; Wesson factory.
