Hydraulic recoil device for handgun applications

A method of reducing recoil in a handgun having a slide and a frame, comprising:

• providing a hydraulic recoil device comprising a cylinder defining an interior hollow compartment, the interior hollow compartment having a first end and a second end, the hydraulic recoil device further comprising a first resilient member completely within the cylinder, a piston assembly arranged adjacent to the first resilient member and at least partially within the cylinder, the piston assembly comprising a piston head, a piston rod extending from the piston head through the second end of the cylinder, a piston cap opposite the piston head, and a compressible accumulator;
• providing a bushing and a second resilient member arranged coaxially with the first resilient member and outside of the cylinder, wherein the bushing and the second resilient member are slidable relative to an exterior surface of the cylinder and slidable relative to the slide and the frame of the handgun;
• generating a hydraulic resistance when the piston rod is displaced in a first direction in operation;
• and
• generating additional resistance by the second resilient member when the second resilient member is compressed in operation.

• providing a second resilient member arranged coaxially with the first resilient member and outside of the cylinder;
• to remove an initial jolt in a firing cycle, generating a hydraulic resistance when the piston rod is displaced in a first direction;
• and
• after the initial jolt in the firing cycle, generating additional resistance by the second resilient member when the second resilient member is compressed.
