Let me start out by saying I do not want a child's shotgun. I'm wanting a semi-automatic shotgun to bird hunt/duck hunt with. I'm willing to spend up to about $600 or $700, but it doesn't have to cost that much. I'm 5' 2" and 110 pounds. My rifle is a Ruger compact .308 and it fits like a glove. The specs on my Ruger are Weight: 6lbs, Overall Length: 36.75", Length of Pull: 12.50". I'm definitely not getting any bigger; so I want something that will last me forever. So what do you all think?
