And why is one handle angled differently than the other and why does only one of them have a front sight and neither a rear sight and why does the one in his left hand have an oversized hammer and so on and so forth.I'm more confused by those handguns. Why do they have those handle looking things screwed into the slide?
The artist probably has no familiarity with firearm mechanics and he probably wanted to have something cool on them. He might have seen a Beretta 93R and thought those angled foregrips looked good but again, no familiarity with firearm mechanics.
