One online article says a lot of jurisdictions are no longer accepting "clipped" nails - nailheads with partial heads like you have - for framing. So before buying a gun, if you ever do any work under a permit, find out what's locally true.
Even if you don't, consider that there may be a reason for the code requirement.
But I don't use a powered nail driving device for a living (unless you consider cholesterol-and-grunt power), so take that for what it's worth, which is about two electrons.
