HS-18 Hammer Spring
CGW music wire 18# hammer spring for P-07/09. This is our heaviest defensive weight spring and should only be used with our matching 97041 firing pin spring. It is not recommended to use this with the stock firing pin spring.
The best upgrade is to combine the HS-18 with our 61050 firing pin (includes the 97041 spring), and our super tough 61100 spring steel retaining pin.
TECH TIP: If you want the utmost in reliable ignition, we suggest matching the HS-18 with our 97041 firing pin spring if you are retaining the stock firing pin.
The best upgrade is the HS-18 combined with our 61050 firing pin (that includes the 97041 spring), and our super strong spring steel 61100 retaining pin.
