setting up replacement hammer

[bronco45]

I have a Model 19-4, and the hammer was bobbed by me several years ago.

I have purchased a NOS hammer with hammer nose but no other parts added.

I will swap sear and spring from bobbed hammer.

How do I get the "spring stirrup" out of the rear of the bobbed hammer and into the new stock hammer? Is it pressed in or pinned?

Thanks for your help.

Drive the pin out. Use a punch with a short tip, sometimes those pins are in tight.
