Step 7: Move AegisChung_Arms down and out a bit ( Figure 15.14 ). The
exact Position settings for me were X = 0, Y = -.35 and Z = 0.4 (all visible
in the Inspector for AegisChung_Arms). However, move them to get your
best guess. Play the game and adjust again.

cheated out so they will be seen.
Why?
When testing and moving be sure to stop playing the game to make
adjustments. Moving the arms while the game is playing will work well
right then, but the position of the arms will revert when the game is
stopped. Also, undoubtedly, you'll notice that the arms strangely disappear
altogether on occasion, leaving just the pistol. We need to fix that.
Step 8: Fix the disappearing arm. In the Hierarchy, expand AegisChung_
Arms and look for the ArmsCenter object. This (in Maya) was the actual first
joint of the rig. Here in Unity, it has a Skinned Mesh Render component.
