A recoil spring system for a self-loading pistol type fire arm having a reciprocating breech block slide comprises a pair of compression springs (P) located in respective tunnels (B1, B2) in the side walls of the slide (B), each said spring abutting at its front end against the front inner wall (B9) of the slide and at its rear end against a stop (A1, A2) on the frame (A), which stop on recoil of the slide passes through a slot (B7, B8) at the rear of the slide connecting the tunnel to an external surface of the slide. The springs can be kept safely in the slide even after disassembly thereof from the fire arm.
