The Makarov pistol is the second in the serious of high detail - high accuaracy weapons.
Just like the AK-103, this weapon was entirely made inside 3ds Max and rendered in Keyshot.
The goal was the same, to create a three dimensional dublicate of the real version. Therefore, the entire inerior had to be created as well.
No floating geometry was used, except for the diamond pattern on the grip.
