Anvil Industries do plenty of PMCs in body armour and shirt sleeves, not sure about suits.
They are on the true 28mm side of things (fit Stargrave parts perfectly), but may be worth a look
Thanks, I have a number of them, for Stargrave etc.
Hasslefree MP5 and Anvil Phase Carbines.
The problem is the weapons are 40K scaled (also a material limit - I have written off all the Spectre V1 starter set law figures due to barrel loss and they are metal).
