Firearm quick release pin with arm extension
First Claim
1. A firearm for shooting ammunition, comprising:
- a frame comprising a pair of sides, an interior space within the frame between the sides, a pair of apertures extending from an exterior of the frame through the respective pair of sides to the interior space, and a recess in the exterior of the frame, a slot proximate to one of the pair of apertures in the recess at the exterior of the frame;
a barrel assembly,a mount connecting the barrel assembly to the frame, wherein the mount is positioned within the interior space of the frame and comprises a bore, and wherein the bore is aligned with the apertures in the sides of the frame; and
a first pin fixedly locking the mount to the frame, wherein the first pin is comprised of a cylindrical body and a lever arm with a locked orientation and an unlocked orientation, wherein a proximal end of the lever arm is fixedly attached to a first end of the cylindrical body, wherein the cylindrical body has a first longitudinal axis and the lever arm has a second longitudinal axis that is askew from the first longitudinal axis, wherein the cylindrical body extends through the apertures and the bore to a second end, wherein a distal end of the lever arm is in flush contact with the exterior of the frame when the lever arm is in the locked orientation, wherein the lever arm is comprised of a locking lip at its proximal end, wherein the locking lip extends away from the cylindrical body in a plane perpendicular to the first longitudinal axis of the cylindrical body, wherein the locking lip fits within the slot in the recess at the exterior of the frame in the locked orientation, and wherein the locking lip is rotated out of the slot in the unlocked orientation.

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.
