I've had pretty good experience, even through this virus mess.
I sent a 351C back to them in mid July because two of the chambers wouldn't eject empty casings. I figured that they'd just ream them out or maybe replace the cylinder.
Nope, they determined that it was "unrepairable" and will send me a replacement. That was July 30 and I heard no further until today.
I had a short hold because everyone was busy. When I was connect to the nice young lady in CS, she looked into their computer and told me that the 351C is on back order and they will ship as soon as a batch is produced. She suggested that I call back in two weeks if I don't hear from them.
Dang virus is really slowing everything down. Plus, they are selling a lot of guns and the usual percentage have to go back.
