Just an update on my previous post,since this post has resurfaced.After 3 mos. I finally did get my lock back from TC.It took 3 phone calls,but it was returned with 3 new parts including the tumbler.Guess what? It works just the same as when it was sent to them.I gave up!
The only company that gave better service than the old TC might have been Ruger. Since S&W forget it!
