I have tailored my Corsair, FNA Despot, for armed mission/trade running. My T-8 is going all mining now, mostly because I don't really like to fly it, and trading is going to the Despot. The T-8 lumbers around and just can't defend itself, that sounds like a miner to me. Plus, I hate c1 weapons...
The corsair has 224 units of cargo space, a multi-limpet controller, a space buggy, and is armed to the teeth with 4 Pulse and 2 Cannon, all engineered just nice. As is I've taken it into CZs and Haz Res' with good (but not excellent) results. The Despot won't replace my P2 for dedicated combat, nor replace my Mandy for getting around and scooping, but it easily replaces the K2 that up until recently held that hauling position.
