Proper spring tension is critical for reliable primer ignition — a worn or weakened spring causes light primer strikes and misfires. Spring tension is regulated by the strain screw at the base of the grip frame.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eInstallation Note\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInstallation requires removal of grip panels and sideplate. Spring tension is adjusted via the strain screw.
