a old copy and paste from be's board:
there is a simple method to tell if you're running the appropriate recoil spring in your gun.
Set up a target a coupla feet in front of you, then shoot 2 shots the fastest you can pull the trigger (and never mind the aiming of them).
Try and notice where the second hit goes compared to the first one: if the second hit is lower than the first one, you definitely have a too strong recoil spring, which is pushing so hard the slide in battery that the muzzle dips at the end of each cycle; if your second hit is still above the first one, then you have a too light recoil spring, thus the gun is already in battery but is still recoiling.
In the second case, rather than switching to a stronger recoil spring, you might want to experiment with different combinations of main and recoil springs, since part of the muzzle rise can be traced to a strong mainspring that is hard to overcome by the slide: the slide actually pushing back against the mainspring might be causing too much momentum on your wrists and too high muzzle rise.
FYI, in my .40 SVI 5" competition (where I shoot 185grs bullets @ 175 PF) I use a combination of 14# recoil spring and 17# main spring: with the above test both 1st and 2nd shots are at the same height level
thats all.:thumb:
