I have recently, by way of trade, become the proud owner of a Dan Wesson 357. I have zero previous knowledge or experience with these. I believe it to be a 15-2 model. It has an 8" barrel. I am asking first for overall opinions. I would also like for someone to explain to me why the replacement barrels are so expensive online. If these were all sold with multiple barrels, why so costly? Finally anyone with any general tips, I would appreciate anything u feel I should know. Thanks in advance.
