Your hold on the pistol also effects cycling. I typically use 18 lb. springs in my 1911 because I almost never shoot reduced loads and I hold very tight. If you have a looser hold heavier springs could lead to a problem. With a tight hold there is very little of the recoil energy impulse moving the gun or your arm it all goes to cycling, so the springs can be a little heavier.

The hammer spring also plays a part. Lots of guys reduce the power of the hammer spring to lighten the trigger pull. But this gives the slide less to work against and increases the slide velocity.

As you can see you can play around with these things 'till the cows come home but you're increasing the variables and likelihood of malfunction.

So for me, I use a slightly heavier spring because I shoot full house loads and hold the gun tight, this gives me a little less battering of the gun and keeps my brass from landing in the next county while not compromising function.
