Civilian weapons are common. You can find 2-3 rifles / shotguns in every town with a few pistols strewn about. This is on an average day.
Your issue is that too many people carry automatic weaponry. DayZ is a game where people naturally gravitate towards automatic weaponry because A) they're better B) they're more fun to most. There's plenty for you to use, we definitely shoul;dn't force half of the playerbase to use under powered or weak weaponry just because some would prefer a more survivor approach.
