Hi All. I've gone target shooting and pheasant hunting, but the 590 will be my first-ever gun purchase. I've watched some videos and I've been reading some of the posts on this site and other websites. I'd like to hear 590 owners' opinions on 12 vs 20 gauge. Has anyone ever gone bird hunting with a 590? If yes, how did you like it? Has anyone gotten their gun engraved, or is that a bad idea? Thanks, in advance.
