Claim 19:
20. A method of reducing recoil in a handgun, 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, and a piston cap opposite the piston head, and a compressible accumulator;
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.
