Considering that they cost nearly $1000 new now and you can no longer get one in .454 Casull, yeah I'd say you did pretty good. I've never shot one myself but they have a good reputation. As for Legacy sports, I've only dealt with them once when I ordered a Howa barreled action. Delivery was fast and I didnt have any problems so I didnt really get a chance to test their customer service. But anything you buy from them will have to be sent back to the foreign manufacturer's U.S. facility or a gunsmith that they have a contract with if there is a mechanical problem anyway so I really wouldnt worry about Legacy. They are just an importer of foreign arms.
