I tried searching the net but couldn't find out what the factory spring weights are so that I can order new ones accordingly.
Would like to know what is the average weights are from similar full sized 1911 in 45 and in 9mm.
 
10# is typical for the recoil spring. Could be upgraded to 11 or 9 depending on the ammo you are shooting. According to Wilson Combat, they run a 11# spring in their full sized 1911 9mm.

Mainspring/hammer spring standard is 23 lbs. I use 19 lbs and have had zero FFF malfunctions.

Springs are inexpensive - grab a few different weights and experiment.
 
I use a 9lb recoil and 19lb mainspring in my 1911 9mm and these work pretty well for me.I dont shoot particularly heavy reloads however(124gr bullet at 1050fps)

In 45 usual recoil spring is 16lb with mainspring 23lb.
