What spring are you talking about?
Have put in the Apex Spring kit, polymer trigger and the lighter sear spring. World of difference with no problems at all. Even put the 20lb stainless guide rod. Mine is the SW40VE, actually selling it today for the SD40VE to go with my SD9VE. The SW40VE is from 2008.
So I contacted jeff about the spring come to find out I have the sear block with the "pressed pins" in it... go figure 22.5 million sigmas and im one of the ones with the pressed pins.... anyway he said send him the spring and the sear block assembly and he would fix it for me so not a total loss but was excited to do my first mod by myself
