He does recommend switching to a heavier spring as the gun wears in, however.
Keep in mind that a 1911 slide is pretty damned heavy.

Most guys that are loading their own ammo or are shooting factory 115 grain offerings are running EXTREMELY light recoil springs in their guns. We are talking 9 or 10 pounds. I personally run an 11 with 135k power factor ammo and have run up to 147k power factor 147 grain loads with no issue whatsoever. A 14 will work but might end up dipping your muzzle upon lockup. My gun is also a 5 inch so im not sure how much that will change the recoil characteristics.

What type of ammo are you planning on running out of this?
