I am considering one of these in a trade and have some questions about this model of the single six. First whats the best carry option? Holster? Sling? Horse and cart? Second is there any real accuracy advantage over the 6.5 inch? I have never had one and have only seen two others that I got to coon finger. I have never shot one of these but have one of ever other barrel length. This was put on the blanket to augment the difference in a trade.
