John, the ruger reply is pretty straightforward. That's a polite business way to reply and give them the opportunity to examine the firearm to determine what happened. Even if you have to pay for the shipping one way, it'll be a lot cheaper than having to buy a barrel & get it properly installed.
Plus,, give Ruger the opportunity to study it. If they had a problem, they can not fix it without knowing about the problem or why it happened.
I know. I was the first person to send them a Redhawk many years ago where the barrel seperated from the frame. It was a painless experience for me to send them the gun, with a detailed letter of explaniation of everything. (Bought new, only shot reloads etc.) Well after they had me sign a liability release, (to prove I wasn't injured or planning on sueing,) I had a new gun. It took them a few years to discover it was an issue with the thread lube on the barrels. They even went as far as developing the Super Redhawk due to their uncertanity about why they were having a FEW issues.
Give Ruger the chance to make it right, AND study the gun.
