smith and wesson transfer bar
When did smith and wesson start using the transfer bar system on their revolvers? What models and series numbers do not have this feature? Thanks.

Unless I am wrong, and I could be, Smith does not use a transfer bar. They have a bar that stops the hammer from resting on the frame, but it does not come up and deliver the blow from the hammer to the firing pin. 0 -
Maybe I should ask when they did away with the firing pin on the hammer? Thanks. 0 -
72chevelle: I can't answer your question but my S&W 686 that was made in 1983 has a frame mounted firing pin, hope that helps a little 0 -
Depends upon the model.Some started in the sixties others never did as late as the ninties. Some models were discontinued and never went to a prame mounted firing pin. I nelieve there are a few still left with a hammer firing pin.
The second admendment GUARANTEES the other nine and the Constitution!0 -
Frame mounted firing pins (on center-fire S&W's) started in about 1998..... Same time they began using the MIM (Metal Injection Molding) for small parts such as - triggers, hammers, thumb-pieces, etc.
The piece that's often mis-identified as a transfer bar is actually a hammer block safety, that prevents the hammer/firing pin from making contact with the cartridge primer unless the trigger is pulled. S&W began using this feature during or just after WWII on all revolver models with a letter as a prefix to the serial number, i.e., 'K' (K frames), and 'S' on N frames, etc.
