Hammer Spring

[the hudge]

I would like to lighten the hammer spring on my 9mm Trojan. Has any one had any experience with this?
What is the Lbs on the factory spring and how light can I go?
Also, are there any timing issues that may occur?
The gun has well over 10,000 rnds through it.
And, would a lighter sear spring be an issue.

Not sure what the factory used but 17# and 19# springs are popular for the mainspring.
Lighter than 17# isn't recomended. Try both, easy to do...

STI told me they use 11 pound hammer springs in there 9mm Trojans. I guess I dont need to go lighter.

11 pounds would be the recoil spring not the mainspring which hes referring to as the hammer spring.

For the main spring(hammer spring) most will go 17/19 pounds. For the recoil spring, the common spring weight is 9-11 pounds. It really just depends on you and how the gun tracks for you and what you prefer
