The first issue sold about 21K copies.
Keep in mind, comic book series typically experience a drop of at least 50% in sales between issue 1 and 2, as 1 is the collector's item and 2 isn't.
Issue #2 of SWORD last month sold about 18.5K copies.
#3 hasn't appeared in the shops yet.
Marvel just canceled the series. #5 is the last issue.
If you ever get a gig working comics, here's a little free advice: don't quit your day job.
