OEM Sear Spring

This sear spring is manufactured as a direct replacement to the SIG factory part 1300799-R. and works in all P320 FCUs including: 9mm | .45ACP | .40SW | and .357SIG, for both Manual and non-Manual safety P320 models. 

** Springs purchased as individual parts (one piece per package) **

--

This SIGMECH | R Part (Replacement Part) from ISMI, is an original equipment manufactured sear spring that is engineered and tested to match factory tolerances, and specifications. However, these particular OEM springs exceed factory quality and performance standards by using a special chrome silicon metallurgical composition that makes the sear springs extremely corrosion resistant while also improving wear resistance so that you know your P320 will perform longer and better over time.

NOTE: Sig Sauer classifies sear springs as consumable components where optimal performance will degrade at approximately 3000 cycles. The P320 requires 2 (two) sear springs to function per factory specifications, and both springs should be replaced simultaneously during this scheduled maintenance. It is not recommended to use only one sear spring.
