I just bought a brand new GP100 4" SS, I have read some about the wolff spring kit and trigger pull, My question- The spring kit is only good for DA mode correct? I cant see how it could have any effect on the trigger in Sa, I just took my GP apart and lightly stoned and polished the hammer and sear (I wouldn't suggest this to just anyone as you can easily go to far and there is no return)Before doing this my new GP had a small amount of creep in the trigger pull (I am talking Sa mode only, get on the target cock the hammer and slowly squeeze the trigger) I shoot Sa exclusively but like the option of DA, I can definately see the spring kit making a big difference in the DA mode but can't see how it could have any affect at all in SA, Am I wrong? I would be worried about the light springs from Wolff not having enough power to pop harder primers (CCI)
