"From the factory"- I assume you mean the Wolff factory? The standard Wolff spring is fine. The new Beretta replacement springs (from Beretta) are horrendously weak- weaker than the worn one's we were replacing.
Backstory: We had the Beretta 92D as duty weapons at my dept, and several months prior to Switching over To Sigs, we ordered a large quantity of magazine springs, mainsprings, recoil springs, firing pin springs, etc. All but the magazine springs were of good quality, but I would not recommend Beretta mag springs to anyone.
