The odds are the Model 65 will be around for a long time, but I have to ask why is this a concern? If the issue is replacement parts, you need to keep in mind that the Model 65 has changed over the years and the parts of the different iterations are not interchangeable. So if you want what the model 65 has to offer, buy it and with a life time warranty, Taurus will repair it if it develops a problem.
