This is inspired a little bit by Kalashnikov yes?, oh and the bullet counter, this just came to my mind, isn't it not strategically irrational to show the opponent how much bullets you have left? By this I mean that if the counter was located in a different location where only the user could see, this would be an improvement. Since you've mentioned it, I come to wonder, exactly which part of this gun was inspired by Fallout? Oh and what part do the electrons play in the gun? that cylinder in the upper right part of the gun, is it related to the electrons somehow?
Actually I was not inspired by Kalashnikov with this one. As all my weapons, the ammo counter has a flip switch (like on modern DV cameras) so it can face the user. I just prefer to depict it in an inactive state. If you wanna know about how the electron weaponry work just scroll down and see the other comments. I've explained it once before. As to the Fallout inspiration, I guess just the feel of it all. The stock witch seems to be to small for the gun, the overall simplicity while still being a advanced weapon.
