Anyone who's built the Sinanju knows that it has trouble holding the rifle and it also has the same problems holding the bazooka. Not to mention the shoulder armour and the wings getting in the way. In order to give it a bit more stability, I glued the hand to the rifle.
Now I'm using some extra 2-piece hands (from MG Impulse, coincidentally almost the same size) to hold the bazooka for those poses without the rifle.
After trying it out I realized that they didn't fit together so... time to remove some plastic. Check the green circles to see where. Basically the pegs on both had to be removed along with a bit of the palm.
These two piece hands are way better for holding weapons then the ones that come with the kit, especially after the finger mod I did.
At least now I don't have to worry about the weapon falling out! Poses like this become a bit easier to do but it's still somewhat awkward, especially when trying to pose it with both hands on the bazooka. The Sinanju wasn't made with this weapon in mind but even still... I'd have to say that it certainly doesn't look BAD.
