Then I'd go with a pretty short barrel depending on what suppressor plans are for the future. They may recommend a minimum length for the gases to be able to do their thing properly or to prolong the life of the can.
Plus a reasonable angled grip so you can manage the recoil on that although it should be less than 7.62, you're still taming a rifle size recoil into a pistol.
Honestly, since you're already going the tax stamp route on the shush unit, you might also consider registering a lower receiver as an SBR and just loading a stock on there when it's approved. Just my two cents!
