The 1911 was designed with a 16# spring with 230 hardball in mind. That being said, I run either a 17.5# or 18# in my guns. I think 20# is overkill, especially for defense loads.

Never had experience on a 20# on any of my FS which I think will be too heavy. I have been given advice not to go more than 18.5# and of course you have to make sure your pistol will function well with it giving consideration of course, the type of ammo and mags you are using.
