My concept is with a holstered weapon, but that could be amended. I'm not familiar with the resources available in this scale, so more specific information about the product lines and kit numbers that you wrote about would be appreciated.
Regarding your right arm right arm comment, I don't know which kit you are referring too. The Verlinden figure that is my starting-point has the sleeves rolled-up. Perhaps the hand on the one your suggesting could be moved the Verlinden kit.
