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.
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.

A safety pin locks a barrel latch while the firearm discharges a round of ammunition. The barrel latch safety locking mechanism is incorporated into the frame and is actuated by the trigger assembly. The barrel latch safety locking mechanism engages the barrel latch to prevent movement during firing keeping the barrel latch engaged with the barrel. The firearm is further comprised of a slide switch that is connected to the barrel latch that allows a user to disengage the barrel latch for loading.

A barrel has a barrel body that extends a barrel length and a bore extending through the barrel body. The bore has a cartridge chamber section and a rifled section with a bore diameter. A cartridge shell fits within the cartridge chamber section and the projectile extends from the cartridge chamber section into the rifled section. The cartridge shell with the projectile has a shell length within the bore, the barrel length is less than twice the shell length. The rifled section has rifling grooves between rifling lands, and each of the rifling lands has a land width. The groove diameter is greater than the land diameter by an amount that is more than one half of the land width. The barrel body has an extractor assembly with an arm retractably extending from a cavity. The arm can rotate in the cavity when extended and does not rotate when retracted.
A firearm has a frame, a barrel assembly and a slide assembly which holds a recoil assembly. The slide and recoil assemblies are located above the barrel so that the barrel is situated between the topmost part of the frame and the bottom of the slide assembly. The barrel assembly includes a housing which is covered by the slide assembly and secures one side of the recoil assembly. The barrel assembly can be removably connected to the frame through front and rear mounts that may be secured using removable pins. The barrel assembly can modularly connect with the frame and slide assembly so that different caliber barrels can be interchanged with each other using the same frame and slide assembly. The firearm is operated by the firing system which includes the trigger assembly and linear striker assembly.
In a breech loading firearm, an extractor arm is slidingly arranged within a cavity beneath the barrel. The extractor arm has a retracted position and an extended position. In the retracted position, the extractor arm is constrained from rotating, and in the extended position, the extractor arm has at least one degree of rotational freedom in the cavity without bending. The intermediate portion of the extractor arm is thicker than the distal end such that the second thickness fits within the cavity when the extractor arm is in its retracted position. The reduced thickness at the distal end provides a space between the extractor arm and a wall of the cavity when the extractor arm is in its extended position to provide for the rotation of the extractor arm within the cavity in its extended position. The proximal end of the extractor arm has an angled face.

Roller bearings are incorporated into the upper portion and lower portion of an elongated trigger assembly of a firearm to provide a trigger pull with smooth operation and balance while reducing wear. The roller bearings roll along trigger tracks that are adjacent to the top and bottom of the trigger pull or are formed as slots in the trigger pull. A safety pin locks a barrel latch while the firearm discharges a round of ammunition. The barrel latch safety locking mechanism is incorporated into the frame and is actuated by the trigger assembly. An extractor assembly for rimless shells is incorporated into a barrel assembly of a breech loading firearm.
A modular linear striker has a firing pin assembly, an axial spring and a housing. The firing pin assembly includes a firing pin and a reset spring and may also include a separate slider. The firing pin has a resting position, a cocked position and a firing position. The reset spring biases the firing pin back in its resting position. When the slider is incorporated into the firing pin assembly, the axial spring biases the slider forward with a preloaded force. The housing surrounds the firing pin assembly and the axial spring. The housing has a notched section between its front face and its body section which fits within a setting in the firearm frame. The notched section engages the fitting in the firearm frame so that the modular linear striker is arranged in the proper position and orientation within the frame.

The present invention is an improved barrel for a gun, wherein the gun barrel has an axis and a front face defined by a plane extending perpendicular to the axis. A plurality of ports is formed in the gun barrel. A first set of ports has a first spacing and a second set of ports is spaced apart from the first set of ports by a spacing distance greater than the first spacing.
A trigger mechanism has a hammer, a hammer spring, a disconnect rest and a sear. The sear translates along a longitudinal axis between a rest position and a break point and also moves in an arc around a rotational axis from the break point to a disconnect position. The sear has a hammer side that presses against and rotates the hammer's cam end of as the sear moves between the rest position and the break point and thereby rotates the hammer's striking end around the hammer's pivot point between its seated and cocked positions. The support side contacts the disconnect rest's face as the sear moves between the rest position and the break point. The support side has an edge that is located at the ledge at the break point position. The hammer spring forces the sear to the disconnect position as the edge moves past the ledge.
