When the trigger is at rest, the hammer block physically prevents the hammer from moving forward far enough to strike the firing pin, even if the hammer is accidentally released or the revolver is dropped. Only when the trigger is pulled fully to the rear does the hammer block drop out of the way, allowing the hammer to strike the firing pin and discharge the cartridge. This design provides an essential layer of safety for modern revolvers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAbout the Model 29:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Smith \u0026amp; Wesson Model 29, introduced in 1955, is one of the most iconic revolvers ever produced. Built on the robust N Frame platform to handle the powerful .44 Magnum cartridge, it gained worldwide fame through Clint Eastwood's \"Dirty Harry\" films. Every component, including critical safety parts like the hammer block, works together to deliver reliable and safe performance.\u003c\/p\u003e","brand":"Smith \u0026 Wesson","offers":[{"title":"Default Title","offer_id":41654855696442,"sku":"29120A","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1423\/2020\/products\/DSC08115_44759b4e-c33d-436b-9aff-1a4ff893d4e3.jpg?v=1789490248","url":"https:\/\/usagunsandgear.com\/products\/smith-wesson-n-frame-model-29-hammer-block-44-magnum-29120b","provider":"USA Guns And Gear","version":"1.0","type":"link"}
