Since the Flansmod Download just Stops to work while setting up Forge with Flansmod, I tried to do it "from File". This also did not work, but when I debugged the Program, it told me: Unhandled Exception: file "Toolbox 2.0\TempMCSMP\some Number\FlansMod-dev\" not found. At this Location, I found a File "FlansMod-1.7.10", which is the extracted Folder from the FlansMod.zip File. The Solution is just to rename the Folder inside the Downloaded .zip to "FlansMod-dev".
the Problem with this Pistol is, that it has 2 magazines, one loaded in the Pistol`s Grip and one stored as a Foregrip. The Gun should now first have only the Loaded one, after reloading, it needs both, and when reloading the second time, it should unload the clip, then take the grip one away and then put it/ a new clip into the Grip. To do this, i would have to Overwrite some Methods in the com/flansmod/client/model/RenderGun , but the ModelGun class can`t access it. Another way could be to wait for the Boxes of the Model to be accessed and then replace them, but i am not sure if, and how this could work.
Is your gun loaded by a magazine or by cartridge? If your gun uses magazines set the reload animation to bottom clip. If your gun uses cartridges then add one cartridge, set it to "Ammo" and then put it into the gun.
