Here at Comic Con San Diego and I met no other than Steve Epting himself. I paid him to draw me a awesome cover of Bucky and I will share it later. But browsing through his awesome art I asked him a question that had been itching on the back of my mind. I knew for the longest time that Bucky's HG was not a luger but rather look exactly like Nick Fury's electric needle gun. I asked Steve what he had in mind all those times when he drew Bucky's handgun and why it's so powerful. He answered somewhere along the lines of
"Everyone always asks me 'why would Bucky be using a German handgun?' It's not, it's a specially modified SHIELD handgun."
So there you have it. The handgun is now confirmed to be a SHIELD handgun and not a luger like other artist and guest writers think it is. Ed, Alex and Steve meant for it to be a suped up modified version of Nick Fury's electric handgun. Check out my respect thread for it's capabilities.
