You can order with your safety cut-out.
It will work with the 320 or 250, and if you have any urge at all to acquire another 320, I would suggest spending the $25 for the charging fork for the full-size slide.
You can get ETS 30 round mags, or you can get Beretta Storm mags, and do a bit of Dremelling. Amend2 Mags are supposed to be making 30 rounders in the near future, as is a company in Florida called Plate.
