If they do .Then you have a problem that needs corrected.
I run wolff 13lb recoil springs in my 380 KT and 32 . But I do because I shoot a lot of hotter ammo in them . Not because of a feeding problem. Never had one problem with mag springs in my 32/380 or PF-9
What kind of feeding problems are you having . Maybe a rough feed ramp and needs polished . easy to do. Doesn't need to be a mirror polish Gunsmiths do that to show they did something not because the mirror finish needed.
P-11 feeding problem can also be owner operator also. These little 9mm do have a bit of recoil
