Been trying to learn a little about 9mm & 45acp recoil spring weight effect for follow up shots. Maybe I'm missing something here but there seems to be different opinions on heavier vs lighter springs. Some opinions I've read say a lighter spring will lessen felt recoil and some say a heavier spring reduces felt recoil. Which is correct and is there enough felt difference with either to justify changing the factory recoil spring for shooting factory 124 gr ammo in the Glock 19 or 230 gr in the 1911.
As a side question does 9mm 147 gr ammo have less noticeably felt recoil than 124 gr?
