A surgical clip applier () includes a handle assembly () having a housing (), a trigger (), and an advancing mechanism supported in the housing () and being actuatable by the trigger (). An elongated tube assembly () extends from the housing (). A first shaft () is slidably disposed within the elongated tube assembly () and defines a surface portion (). A second shaft () is disposed through an outer surface of the elongated tube assembly () and is in operative engagement with the surface portion () of the first shaft (). Upon actuating the advancing mechanism, the first shaft () moves distally within the elongated tube assembly () relative to the second shaft () such that the surface portion () of the first shaft () traverses the second shaft () to produce at least one of an audible or tactile feedback.
