Anyone uses Variable weight recoil springs (Wolff)

Anyone uses Wolff Variable weight Recoil springs? I ordered a few and got the package today...

anyone uses them?

wuote from Wolff website

Variable recoil springs reduce the battery load values with increasingly greater recoil load values. This results in easier unlocking, improved recoil energy storage, dampening, feeding, breaching and lockup. Variable recoil springs are particularly beneficial with compensated pistols and when using light target loads where less recoil energy is available

These were originally designed for compensated game guns that might have trouble unlocking.

For a 5" 1911, the Wolff 17# std rate spring is the closest I have found to the original spec of #turns and wire size. I like the ISMI CS 16# spring for normal 45 acp loads in a 5" 1911.

I think for non compensated guns the std rate spring are probably closer the the original design specs.
