This precision-manufactured spring applies constant upward pressure to the sear, keeping it engaged with the hammer notch until the trigger is pulled. When the trigger is pulled, the sear rotates downward against spring pressure, releasing the hammer to strike the firing pin.\u003c\/p\u003e\u003cp\u003eThe sear spring must provide precise tension - enough to keep the sear securely engaged with the hammer, but not so much that it creates excessive trigger pull weight. This delicate balance is critical for safe and reliable trigger operation. The spring also helps the sear return to its engaged position after each shot, resetting the trigger for the next pull.\u003c\/p\u003e\u003cp\u003eA worn, weakened, or damaged sear spring can cause dangerous malfunctions including light trigger pull, sear slippage, hammer follow (hammer following the slide forward without trigger pull), or failure to reset. These issues can compromise both safety and reliability. Replacing it with a genuine Smith \u0026amp; Wesson factory part ensures proper sear tension and safe trigger operation.\u003c\/p\u003e\u003ch3\u003eWhy Choose Factory OEM Parts?\u003c\/h3\u003e\u003cp\u003eWhen it comes to critical fire control components like the sear spring, using genuine Smith \u0026amp; Wesson factory parts ensures:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecise spring rate:\u003c\/strong\u003e Manufactured to exact Smith \u0026amp; Wesson specifications for proper sear tension\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable operation:\u003c\/strong\u003e Correct spring force ensures safe sear engagement and trigger function\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuality materials:\u003c\/strong\u003e Proper spring steel composition ensures durability and resistance to fatigue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerfect compatibility:\u003c\/strong\u003e Designed specifically for TSW and CS series pistols with guaranteed fitment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLong-lasting performance:\u003c\/strong\u003e Factory springs are built to withstand thousands of trigger pulls\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety assurance:\u003c\/strong\u003e OEM parts meet Smith \u0026amp; Wesson's strict quality and safety standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\u003cp\u003eInstallation of the sear spring requires disassembly of the pistol frame and removal of the fire control components.

Ensure your pistol is unloaded and pointed in a safe direction before performing any maintenance or parts replacement. After installation, verify proper sear engagement, trigger pull weight, and hammer function with snap caps before live fire.\u003c\/p\u003e\u003ch3\u003eAbout Smith \u0026amp; Wesson TSW and CS Series Pistols\u003c\/h3\u003e\u003cp\u003eThe TSW (Tactical Smith \u0026amp; Wesson) series represents Smith \u0026amp; Wesson's enhanced 3rd Generation pistols designed for law enforcement and tactical applications, featuring improved sights, ergonomics, and reliability.
