Default Question on a K-22 hammer pivot pin

Can anyone confirm the pin type I have on my 1947 K-22? I took some pictures. It would appear to be a screw in type. It may not be screwed in enough. It may be slightly bent. Just checking for now. The previous hammer which was not original had wear at the right top and so did the frame. If I look at the outside it looks like it's not as flush as it should be. On the off chance it is slightly bent are there replacement studs available? What tool is used to tighten it or remove the pin?

The first thing I would advise is to confirm the hammer pin is straight. You need a small square to check the pin at four locations 90 degrees apart.

The hammer side that rubbed the frame may not be square to the pin hole.

That is a pressed stud, not a threaded stud. The pressed studs are not all polished flush like they should be. Some look like yours and others are darn near invisible.

The change order to replace the threaded stud with the pressed type was issued on January, 18, 1946, and the change was implemented shortly thereafter. By 1947, it appears that all K frame revolvers were fitted with the pressed studs.

I would have no idea where you could get a replacement stud, nor how to R/R the one you have. Others here may be able to address that part of your question.

I thought it was pressed, but I'm confused by the serrated edge on the stud just like in picture in the book.

I'll have to see if I can rig up a tool.

I see what you mean and I have no explanation. Sorry.

Yes. Confusing.

I've checked it by gauge and while one side has a wider gap I'm inclined to leave it alone for now. The hammer I replaced the other with seems to fit better and even though it looks close I don't see contact. Perhaps wiser to leave well enough alone.

It's possible that the pivot hole in the original hammer wasn't perfectly perpendicular to the sides of the hammer surface. They actually use a gauge to check for that sort of thing, but it probably wouldn't have been a 100% check.

Yes. Since the hammer that was on it when I bought it was not original it's possible it was not checked properly. The original probably fit perfectly.
