Abstract: A quick release pin is used in a firearm to secure a barrel assembly to a frame and a recoil assembly within a slide. The cylindrical body of the pin functions similarly to traditional takedown pins and pivot pins used with firearms while the lever arm has unique features that are an improvement over traditional takedown pins. The arm has a locking lip at its proximate end, a detent at its distal end, and a cut-out center section which is thinner than the distal end and proximal end. The cut-out center section creates a space between the arm and the firearm's side when the arm is in its locked configuration which provides side edges for a user to grasp the edges of the arm between a finger and thumb while the thicker distal end of the arm is in flush contact with the side of the firearm.

Abstract: A slide assembly quick release pin and arm that secure a recoil assembly within a slide. The pin is inserted through a pair of apertures in a front portion of the slide and through a bore in the nose portion of the recoil assembly aligned between the apertures. As the pin secures the recoil assembly within the slide an arm attached to the end of the pin rests in a recess, flush to the body of the slide in a locked orientation. The pin arm is rotated from a locked orientation within the recess in the assembled configuration to an unlocked orientation out of the recess before the firearm is disassembled. Additionally, the arm acts as a handle for grasping and rotating to provide a mechanical advantage when a user is removing or inserting the pin into the apertures and bore.
