1911 recoil springs

looking for  assortment for a SIX inch springfield 1911. wanted a 10lb  equivelent. Any help would be great.

Wollf has 6" springs of various weights for 1911 longslides as well as the calibration pack. See here: https://www.gunsprings.com/COLT/1911%20GOV'T%20PISTOL/cID1/mID1/dID1#800

They make a spring plug for a 6” that uses 5 “ springs
 STI makes them and I found this from Fusion.

I have a 6" gun, and I ended up going with the spring plug like David mentioned.  Mine was from Caspian . https://www.caspianarms.com/productdisplay/guide-plug-6-standard-hole
My gun never worked right with those long springs from Wolff
