[QUOTE=e-luder;1770350]That's normal. When you upgrade the strength of the recoil spring, you also create more resistance for the rear slide stroke. That's why the felt recoil of your gun seems to be "less powerful".
it is not the recoil to be less powerful but the shot, also if I don't have a chrono the fps of the bb are much less for sure....at soon as possible I upgrade to the stronger Guarder Hammer pring to see improvements..
