Can anyone tell me at what point S&W changed the trigger stud from a screw-in to press-in design? I have a cal.22 Combat masterpiece of early 50's vintage that I suspect the stud is broken. So far, I found a new Victory model stud with threaded shank & am wondering if it will fit. I don't really want to disassemble the trigger assy. without having replacement parts ready at hand. Thanks in advance, John.

You really need to take yours apart and make sure there is a problem with the trigger stud before you proceed further. Replacing it is a gunsmith or factory job.

+1 to what DWalt said. A broken trigger stud is not a common malady nor is it a fix for the average home smith. What symptoms is the gun displaying to suggest the trigger stud is broken? While I have not dealt with them personally, members of this forum have mentioned several talented gunsmiths in your part of the country. It will be necessary for you to go to one of them as the factory is not likely to work on anything as old as yours... they generally won't go before the first of the Model-Numbered guns.

Yup, obviously I am going to take it apart to determine the fix. I would like to know beforehand if the stud is threaded or pressed in. I have facilities to press out and even mfg. a new stud if necessary, and have enough working knowledge to be comfortable with complex mechanical assemblies. I see some good info on the 'smithing page related to this problem, but no reference as to when the change was made.

I don't know, but the K-frame hammer stud went from threaded to pressed in ca. 1946, so logically so would the trigger stud. You might get more informed opinions from those in the gunsmithing area of the forum.

The management order was issued on January 18, 1946. Production of the change happened fairly quickly.
This was a few months before the first postwar K-22 was produced.
