I have a Taurus model 650, the CIA model with the enclosed hammer, similar in appearance to the S&W centennial model. My question is will the spring kits (that are sold by Brownells and other places) for the Taurus model 85, the small frame .38 also fit the 650? Does the model 85 and 650 have the same hammer and trigger return springs? I can find spring kits for the 85 but none listed for the 650.
