I know that, technically, John Marston is married and wouldn't be considered a bachelor, but that's not going to stop me from adding him to this list of "Gruff, bearded men with dark hair and guns who are considered sexy by at least one writer."
There are only a few times I've seen a character supposedly considered an "expert" at guns actually live up to their reputation. And darned if Marston doesn't live up to his. I actually believe that he could hit a target with both eyes closed, and that belief has got me all twitterpated.
Who cares if he's not technically a bachelor? If you want to get really technical, then nobody gets to love John Marston because he's dead.
