I know people have different views, just will say have been shooting for many years, loading over 25, and do minor gun work. I carry the Kimber CDP 4”, it has the Officer Size grips makes a good carry gun.
I tend to load even practice stuff on the warm side and run a spring with more then stock weight. I use shock buffs for practice not carry with +p that is if the gun functions properly. I have a 1911 9mm Springfield with a 9lb spring, put in 12, and it runs fine.
I have not owned a gun with the dual springs but my answer would be, if you shoot stiff ammo, add some weight. That is that as long as it feeds fine.
My 2 cents
