I changed it and the trigger, way better.
The problem with lighter springs is that they don't operate as positively as a stronger one. Lighter Hammer/Striker springs mean your primers won't be hit as hard as they would otherwise. Lighter recoil springs mean the slide will slam back harder and might not completely chamber a round when your life counts on it and cracking the frame. That's why you see so many failures at matches. "Tuned" guns at the hairy edge of reliability.
Conversely some will go with a heavier recoil spring to minimize recoil because the slide is barely cycling enough to eject and load the next round. Standard ammo could short stroke again leaving you doing a jam clearance drill when your life is in the balance. If you are going to start "Tuning" your gun you actually have to be in "Tune" with the gun. I work up loads for each of my guns for this reason. My Max9 for instance averages around 6-8" at 25yds. 124gr Sig V Crowns going 1,150 go into 2" at 25yds and don't abuse the gun.
Tuning guns are like tuning cars. One numbnuts that I know added a bigger turbo and waste gate to his factory turbo car and was upset when it would shut down every time he tried to get on it because the factory computer was detecting conditions that according to factory settings could damage the motor. It's a Deep Dark Rabbit Hole when you start screwing with things that actually work.
