It will NOT fit round butt models, which use a different strain screw design. Always verify your revolver's grip frame configuration before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation Notes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eProfessional gunsmith installation recommended. While the strain screw is accessible from the bottom of the grip frame, proper adjustment requires expertise to achieve the correct balance between reliable ignition and acceptable trigger pull weight. Over-tightening can cause light primer strikes; under-tightening can result in heavy trigger pull. Some fitting may be necessary to ensure proper thread engagement and function.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePart Number: 29173C\u003c\/li\u003e\n\u003cli\u003eModel: 29-2\u003c\/li\u003e\n\u003cli\u003eFrame Size: N Frame (Large Frame)\u003c\/li\u003e\n\u003cli\u003eGrip Frame Type: Square Butt\u003c\/li\u003e\n\u003cli\u003eCaliber: .44 Magnum\u003c\/li\u003e\n\u003cli\u003ePart Type: Strain Screw\u003c\/li\u003e\n\u003cli\u003eCondition: Used\u003c\/li\u003e\n\u003cli\u003eManufacturer: Smith \u0026amp; Wesson\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAbout Square Butt vs Round Butt:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSmith \u0026amp; Wesson N Frame revolvers were produced with two grip frame configurations: square butt (larger, more traditional) and round butt (smaller, more concealable). The square butt provides more gripping surface and better recoil control, making it popular for full-size service and hunting revolvers. The strain screw design differs between these configurations, so parts are not interchangeable.\u003c\/p\u003e","brand":"Smith \u0026 Wesson","offers":[{"title":"Default Title","offer_id":41240016977978,"sku":"29173C","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1423\/2020\/files\/DSC05158.jpg?v=1770834780","url":"https:\/\/usagunsandgear.com\/products\/smith-wesson-n-frame-model-29-2-strain-screw-for-square-butt-44-magnum-29173c","provider":"USA Guns And Gear","version":"1.0","type":"link"}
