V.V. website does list loads for N320 with a 124 gr FMJ RN from 3.4 to 4.0 gr. I know everyone says start low and work up. I have found when loading for semi-auto pistols that starting at the lowest load gives you bullets with not enough oomph to cycle the slide reliably. For this particular one, I'd probably start at 3.6 and work up.

I love W231 for 9mm. I shoot a powder coated 120gr cast TC. The most accurate load I've found for that is 4.0 gr of W231.

As always, check the loads for yourself.
