Small pistols like Shield's and 3 inch 1911's have stiffer springs for a reason. If weaker springs in a small pistol were a good idea, all of them would come with weaker springs.

People choose the EZ because of hand strength issues, so it's no small stretch to think that many issues are limp wrist related.
Couple that with weaker recoil and mag springs and it's no wonder that there are so many threads about issues with the EZ.
