Doubt about anottate classes

I’m trying to build a model to detect knifes and handguns (pistols and revolvers), the training batch is like 1000 images (i know it’s little), and a question that i have is: get a picture of a handgun in a desk, showing her entirely, and get another pic of a man holding a handgun, showing only the upper part of the pistol, and some times the trigger. I make another class for this situation (only the upper part), or I leave this way (all angles is the same object)?

This pic is a example. The IA will really learn with this example?
