Somebody told you wrong. I'd at least double that number on the OEM spring, but get some Wolff springs and don't look back. The poundage of the springs will vary by opinion. A really good source for information like that would be the Kimber forum over on the 1911 forum website (you probably already go there): http://forums.1911forum.com/
I got a used UCII that is now my daily carry, and it likes the Winchester "white box" ammo fine, also eats my reloads without complaint. I find that the gun is more narrow than revolvers and most Glocks, and that it's caliber (.45 ACP, God's caliber) is sufficient to ease my mind. Good carry gun.
