Claim 0:
1. A hydraulic recoil device for a handgun, comprising:
a cylinder defining an interior hollow compartment, the interior hollow compartment having a first end and a second end;
a first resilient member arranged 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;
a compressible accumulator arranged within the cylinder; and
a second resilient member arranged coaxially with the first resilient member and outside of the cylinder, wherein when the hydraulic recoil device is in a battery position in the handgun a length of the second resilient member is equal to or less than a length of the cylinder;
wherein when the piston rod is displaced in a first direction in operation, a hydraulic resistance is generated by the piston assembly, and when the second resilient member is compressed in operation, additional resistance is generated by the second resilient member.
