US12339086 - Hydraulic dampened high mass rotary barrel recoil system for handgun

The patent describes a hydraulic dampened rotary barrel locking system for handguns that enhances accuracy and reduces felt recoil by optimizing the slide-to-barrel mass ratio and incorporating hydraulic dampening. This system features a moveable slide, a barrel with locking lugs, and a keyway slot that facilitates the barrel’s movement during operation, improving overall firearm performance.

Claim 1

1. A rotary-locking firearm comprising: a frame; a slide removably mounted to the frame and configured to move from a forward position to a rearward position along the axial length of a barrel, comprising a rear end and a discharge end, a barrel bore operable to receive a barrel, and an extended lug boss with a front face and a rear face disposed outside said barrel bore and at said discharge end; wherein expanding propellant gases from a fired cartridge force said slide rearward, and wherein said extended lug boss comprises a keyway slot configured to guide the barrel after the firearm unlocks; a rotary locking barrel comprising an external surface, an inner bore, a discharge end, a rear end, a control rail lug of defined length which rests against the rear face of said extended lug boss when the firearm is in the full battery position; and a cam assembly operable to facilitate the axial rotation and disengagement of said rotary locking barrel from said slide as the rotary locking barrel and slide move rearward under recoil from a fired cartridge. a frame; a slide removably mounted to the frame and configured to move from a forward position to a rearward position along the axial length of a barrel, comprising a rear end and a discharge end, a barrel bore operable to receive a barrel, and an extended lug boss with a front face and a rear face disposed outside said barrel bore and at said discharge end; wherein expanding propellant gases from a fired cartridge force said slide rearward, and wherein said extended lug boss comprises a keyway slot configured to guide the barrel after the firearm unlocks; a rotary locking barrel comprising an external surface, an inner bore, a discharge end, a rear end, a control rail lug of defined length which rests against the rear face of said extended lug boss when the firearm is in the full battery position; and a cam assembly operable to facilitate the axial rotation and disengagement of said rotary locking barrel from said slide as the rotary locking barrel and slide move rearward under recoil from a fired cartridge.
