The spring drives the stop upward into the cylinder's locking notches, indexing each chamber precisely in line with the bore. A worn or broken cylinder stop or spring causes the cylinder to fail to lock, resulting in misalignment between the chamber and barrel — a serious safety and accuracy issue. This is a genuine S\u0026amp;W factory used cylinder stop and spring pulled from a Model 43 Airweight.\u003c\/p\u003e\u003ch3\u003ePart Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 81-43-E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Used\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Cylinder Stop \u0026amp; Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Smith \u0026amp; Wesson J Frame Model 43 Airweight (.22 LR Rimfire \/ .22\/.32 Kit Gun)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM:\u003c\/strong\u003e Smith \u0026amp; Wesson factory part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility\u003c\/h3\u003e\u003cp\u003eThis part fits the S\u0026amp;W J Frame Model 43 Airweight (.22\/.32 Kit Gun), a rimfire .22 LR revolver.
