Figured I'd write a little bit more about my experience with Ruger's customer service. Years back, I bought an old model Bearcat (aluminum frame) that had a defect in the frame. It was sent to Ruger for inspection, deemed unrepairable and they sent me a new one. A little later on, the Blackhawk I had had some issue that I can't recall- it went off to Ruger and they fixed several issues with it.
Within the past several months, I've had three Ruger revolvers go back to Ruger. All three were purchased used. The first was a Redhawk that had one chamber bc gap that exceeded their tolerances. Unfortunately, they weren't making that Redhawk with the single piece barrel anymore, so they offered my the msrp value of that one towards another revolver with some exceptions. Since the Redhawk was a 45 colt/45 acp, I chose a flattop convertible 45 colt/45 acp which hopefully I'll be getting soon. The next two were both Blackhawks- the first a 357/9mm convertible and the other the 50th anniversary 357. The 357 cylinder for the convertible had endshake that exceeded their tolerances- that was sent in and returned with a new cylinder within two weeks (maybe a little less). The 50th anniversary had a front sight that was slanted a bit too much to the right (overclocked barrel is my guess), and even with the rear sight all the way to the right, it was still left of the target a good 2-3" at 10 yards. That was sent to them on the 2nd of this month and comes back today.
The first four were sent back through the shop I purchased from. The last one I called Ruger and paid $30 for a shipping label. UPS arrived at my house and picked it up the next day.
Again, these were purchased used. Ruger has taken care of me. They are a good company to deal with.
