About 10 years ago, I ordered a Tyler T for my mod. 66 RB snubby, waited months, and when it arrived, it didn't mate properly, leaving a large, noticable gap between the trigger guard and frame. I returned it certified mail, with a note explaining the defect, asking them to replace it. Never heard back from them, though I sent followup e-mails. Never received a replacement or refund.
After giving up ever getting the replacement from them, I found one online that fit.
More recently, I bought a boxed Tyler T for my J frame that was advertised in the Classified section on this site. I'm no longer in the market for Tyler T products, but in case I need another adapter, I'll find one online from a private seller who won't rip me off, as Tyler T did.
