Regarding the stronger recoil springs, I have found that a stronger recoil spring results in less felt recoil. On my LCP, I changed out the recoil spring to the strongest one that Wolff offered, and it lowered the felt recoil in my hand. I actually tried this because other LCP owners had done the same thing in order to reduce felt recoil. Not trying to confuse things, but just trying to share some experience and information.
