Softest 9mm 1911 Load N320 - no PF?

I might try the N310 load

Tried two extremes today: 160gr coated with 3.1gr WSF and 115gr coated from 3.9 down to 3.4 gr N320. The 160gr was softer than our 147gr usual load (3.3gr WSF). Frankly, I was surprised I got down to 3.4gr N320 behind the 115gr bullet since the VV load tables start at 3.9gr. At 3.4gr it's almost a 22lr and I'm sure could have gone a bit lower. I'll probably chrono later this week, but the N320, as many folks have said, is a winner. I've wanted to try it for a long time, but now that it's available anyone want to buy 16 unopened pounds of WSF (Just kidding, my wife won't let me sell anything in case we have a Zombie invasion). BTW, our 9mm 1911s are almost stock sprung: 10 lb Wolff recoil spring and 19lb Wolff mainspring.

Thanks, all, for the suggestions.
