Help me decide on a vector

I want to be able to run it as a SBR. So which model would make the easiest/cheapest conversion?

Also, I was thinking about 10mm, will it run any off the shelf rounds?

Pistol version is easiest to convert to sbr. Just need to buy the stock, and brace can suffice in meantime. If you get rifle version, you'll have to send back to factory or get barrel cut.
