After a few thousand cycles the recoil spring no longer returns the slide with the authority it had, and the hammer spring no longer strikes the valve as hard, and the gun gets vague in a way that is hard to put your finger on.\u003c\/p\u003e\u003cp\u003eThis set is the unglamorous fix: a standard-weight recoil spring and a standard-weight hammer spring, both at the original specification.
