v21 Super Shotgun with properly holding hands (Updated) addon

This is the standard v21 SSG with hands holding it the same way as Mike12's Black (Silver) SSG Moddb.com

You may say that the right hand should not be visible, as it isn't visible when holding the regular shotgun, but if you look at their world sprites, you will notice that the thumb groove for pump-action shotgun is deeper than the SSG's and lets the right hand to stay low enough to be out of the view.
